Description

[Technical field]

[0001] The embodiments described below relate to sensors, and more particularly, to flow sensors. [Background technology]

[0002] Existing fin sensors have problems with generated mode separation. Typically, there is minimal frequency difference between in-phase and out-of-phase modes, which confounds calculations of fluid flow characteristics. Also, when existing fin sensors are allowed to curl, there is little amplitude contrast to derive phase difference measurements that yield flow characteristics.

[0003] In existing fin sensors, measurements are confounded by significant net movement from the center of the conduit in which they reside toward the sensor assembly. The reason for this is that the axis of rotation of the fins is controlled by the fin position on the plate and the position of the driver. The axis of rotation of the fins is typically about the edge of the base on which the fin resides. This creates imbalances and, as a result, errors and problems in calibration. Forces from the common mode cause net motions in the process connections. Also, the tubes and balance bars can be difficult or impossible to drive to an equal common mode shape. The resulting imbalances can lead to calibration and measurement errors. These issues limit the effectiveness of fin sensors and make them impractical for many industrial applications. Therefore, there is a need for an improved fin sensor. Summary of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0137] 1-12 and the following description are illustrative of a fin coupler assembly and a fin sensor. Specific examples are provided to teach those skilled in the art how to make and use the best aspects of the embodiments of the balanced base assembly. Some conventional aspects have been simplified or omitted for the purpose of teaching inventive principles. Those skilled in the art will appreciate variations from these examples that are within the scope of the present disclosure. Those skilled in the art will appreciate that the features described below can be combined in various ways to form multiple variations of balanced base assemblies for fin coupler assemblies and fin sensors. As a result, the embodiments described below are not limited to the specific examples described below, but only by the claims and their equivalents.

[0138] 1 shows a perspective view of an embodiment of a flow sensor system 100 having a fin-type sensor. The system 100 includes an upstream transducer 104a, a driven transducer 104b, a downstream Transducer 104c, base 106, first fin 108a, second fin 108b, conduit 110 (not shown), meter electronics 112 (not shown), first fin protrusion 114a, second fin protrusion 114b. , a base coupler 116, a balance rib 118, a first fin coupler 120a, a second fin coupler 120b, intersecting axes 131 having a first direction 133 and a second direction 135, an upstream direction 143 and a downstream direction 145. 1 through 4 and 10 through 12 may not be to scale for various embodiments of system 100.

[0139] The flow system 100 can determine flow characteristics using a fin sensor 102. For example, the fin sensor 102 can drive an element of the fin sensor 102 using a transducer to drive vibration of the element of the fin sensor 102. The transducer can , may be any type of driving or pick-off element, e.g., a piezoelectric element or a magnet and coil configuration. Any, some, or all of the transducers may measure the phase or time difference of the signal measured by the transducer to determine flow characteristics, such as to determine mass flow rate. In an embodiment, the fin sensor 102 is a Coriolis flow sensor that uses a transducer configuration that may rely on Coriolis forces across elements in the fin sensor 102 to generate these flow rates. The phase difference or time delay may be generated by the driving and measuring elements, e.g., by vibrating the base and measuring the response at the transducer, by vibrating the fins and measuring the response at the fins, or by comparing the signal used to generate the vibrations (the driving signal) to the response at the fins. The flow rate measurements are calculated based on the phase difference and / or frequency response obtained by the transducers 104a-c. The fin sensor 102 determines the frequency of the vibration and The frequencies can be used to generate density measurements by determining density from those frequencies using methods known in the art For example, density measurements can be generated from frequency response signals acquired by transducers 104a-c. The viscosity measurement may be based, for example, on the two resonant frequency drive phase difference, which may be derived. and derived in the fin sensor 102 from the transducer measured phase difference or time delay. Vibratory meter flow, density, and viscosity measurement methods are all well established in the art. The fins are bonded at specific locations using fin couplers. In various embodiments, the fin sensor 102 may be a Coriolis flowmeter, a fin The meter may be one or more of a standard meter, a standard meter, or a fork meter (possibly having either fins or tines).

[0140] The fin couplers 120a and 120b can be used to enhance mode separation between in-phase (hereinafter referred to as "IP") and out-of-phase (hereinafter referred to as "OOP") modes. In an embodiment, the OOP mode may be a mode in which the first fin 108a and the second fin 108b vibrate at or about a 180 degree phase difference with respect to each other. To increase the sensitivity of the measurement of the sensor 102, more curling motion can be introduced. In an embodiment, the base 106 may be a plate having a thin central portion and a thick outer portion along the intersecting axis 131. The base 106 may also include a balance ring to control deflection. The base may have a vertical projection 118 that may limit the net movement of the fin sensor 102 in a vertical axis 151 relative to the conduit to which the base is coupled.

[0141] In an embodiment, the fin sensor 102 may have two fins, a first fin 108a and a second fin 108b. The first fin 108a and the second fin 108b are fins that are at least partially immersed in the flowing fluid during operation of the fin sensor 102. More fins may be used. Embodiments are contemplated in which 3, 4, 5, 6, 7, 8, 9, 10 , 11, 12, 13, 14, 15, 16, or more fins are contemplated. In other embodiments, tines can be used instead of fins, with the tines having some or all of the same characteristics and arrangement of the fins 108a and 108b disclosed herein. Where this specification refers to fins, this specification also contemplates embodiments in which tines are used.

[0142] The fins 108a and 108b may be arranged parallel to one another and with lengths parallel or substantially parallel to the expected path of fluid flow within the conduit. The fins 108a and 108b may be arranged to have portions that extend through the base 106, and the fins 108a and The fins 108a and 108b may have fin protrusions 114a and 114b on the side of the base 106 (outside 344 in FIG. 3) that does not have a portion of the fins 108a and 108b that is immersed in the flow fluid (see FIG. 3). 3. The side having the immersion fluid is the immersed side 342 shown in FIG.

[0143] The fins 108a and 108b may have a free edge 199, possibly defined as the extreme end of the lower 155 of the fin. and 120b) are used to optionally connect a portion of the free edge 199 of the first fin 108a to the second fin 108b. By bonding a portion of the free edge 199 of the fin 108b, or possibly by bonding other portions of the fins 108a and 108b, movement of the free edge 199 of the first fin 108a relative to the bonded second fin 108b can be limited.

[0144] The fins 108a and 108b may be coupled to one another using one or more fin couplers. Fin couplers 120a and 120b are elements that couple the movement of fins 108a and 108b at specific locations on fins 108a and 108b. For purposes of this specification, the first fin The first fin coupler 120a is shown as the upstream fin coupler 143 relative to the second fin coupler 120b. In various embodiments, any number of fin couplers can be used to couple adjacent and / or non-adjacent fins. For example, the couplers coupling each set of coupled fins may be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, The number of combiners 120a and 120b may be 1, 12, 13, 14, 15, 16, and any other number. In various embodiments, a certain number of fins may be combined or a certain number of fins may not be combined, such as all of the fins, three-quarters of the fins, two-thirds of the fins, half of the fins, one-quarter of the fins, one-third of the fins, one-eighth of the fins, one-tenth of the fins, etc. Fins of this ratio may be combined.

[0145] In an embodiment, one, a combination, or all of the fins 108a and 108b are integral with the base 106. For example, substantially in this context can mean that the fin does not extend to a portion of the base 106 that is used to couple the base to a conduit or a portion of the base that is directly adjacent to a portion of the base 106 that is coupled to the conduit 110 and / or the base coupler 116.

[0146] Conduit 110 is a conduit through which a fluid can flow. The following types of conduits can be used. Although the conduit 110 is not shown in FIG. 1, the manner in which the flow conduit and the flow sensor, e.g., fin sensor 102, are coupled to the conduit may be different from that of the flow sensor. It is well known in the art.

[0147] The fin couplers 120a and 120b can couple the fins 108a and 108b at any number of positions between the fins. For example, the fin couplers 120a and 120b can couple the fins 108a and 108b at substantially the same positions on corresponding faces of the fins 108a and 108b, and in some cases the fins are arranged such that the fin couplers 120a and 120b are parallel or substantially parallel to the cross axis 131 when the fins 108a and 108b are positioned at the same positions in a plane defined by the flow axis 141 and the vertical axis 151 (e.g., if the fins have the same shape and size).

[0148] Embodiments are contemplated in which the fin faces do not have a plane. In this case, the areas mentioned in the previous paragraph may represent projections from their relative areas of the largest fin cross sections in any plane defined by the flow axis 141 and the normal axis 151, with the relevant areas projected onto the area of ​​the fin face (e.g., the inner surface of 108a) facing the inner surface of another fin (e.g., the inner surface of 108b) projected along the line of the intersecting axes. For the purposes of the claims, these are referred to as "projected areas."

[0149] Fin couplers 120a and 120b may be of different shapes and configurations, for example, one or more of fin couplers 120a and 120b may be rod-shaped or cylindrical, for example. Shapes, brace bars, beams (in some cases, when there is no flow, square, circular, triangular , other polygons, ellipses, etc., having a cross section relative to the plane defined by the flow axis 141 and the normal axis 151), a strip having flat areas (when no flow is present, the cross section is substantially parallel to the flow axis 141 and normal axis 151), and a vertical axis 151; or 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 120, 130, 131, 140, 14

[0150] The fin couplers 120a and 120b may be constructed from any number of materials and may be formed from the conduit 110, the vehicular one of the base 106, the transducers 104a-c, the fins 108a and 108b, and / or the portions of the fins 108a and 108b to which the fin couplers 120a and / or 120b are coupled; The fin couplers 120a, 120b may be constructed from the same material throughout the fin sensor 102, or they may be constructed from different materials in any combination or all. may have different compositions between

[0151] One or more of the fin couplers 120a and 120b may be A flexible material is used to allow some degree of flexure and modal flexibility in one or more of the following: The fins 108a and 108b may be made of a material that, in some cases, allows greater flexibility of movement of one or more of the fins 108a and 108b, or one or more of the fin couplers 120a and 120b, in some modes than in other modes. Flexural and modal flexibility in one or more of the gyro couplers 120a and 120b is limited. The fins 108a and 108b may be made of a rigid material to provide increased flexibility of movement of one or more of the fins 108a and 108b, or one or more of the fin couplers 120a and 120b, in some modes, compared to other modes. The fin couplers 120a and 120b may be assembled with the fins 108a and 108b, and this assembly is referred to herein as a fin coupler assembly.

[0152] The fin couplers 120a and 120b can increase the curl of the fins 108a and 108b when the fins 120a and 120b are driven in an out-of-phase mode. The fin couplers 120a and 120b can increase the axial stiffness, which can result in increased curl. The increased curl can indicate that the fin sensor 102 is better able to couple the fins to the flowing medium and reduce the Coriolis mass flow rate, similar to a typical Coriolis mass flow meter, fork meter, or fin meter, as the case may be. Additionally, the curl created in the fins 108a and 108b by including the fin couplers 120a and 120b in out-of-phase mode can provide a different, potentially higher frequency, response to the fin sensor 102 that is similarly driven in the in-phase mode. The axial stiffness provided by fin couplers 120a and 120b also keeps the tips of free edges 199 of fins 108a and 108b stationary, essentially creating a mode separation. It can make stationary or at least limit the mobility of the free edges of the fins 108a and 108b relative to the mobility that the fins 108a and 108b would have if the fins 108a and 108b were not coupled by the fin couplers 120a and 120b, similarly reducing their drag in the flowing medium and potentially making them less impactful on fluid-structure interaction.

[0153] The fin couplers 120a and 120b should be understood as functional elements that function separately from the base 106 and the transducers 104a-c. The fin couplers 120a and 120b may be separate from the base 106 and the transducers 104a-c, and the fin couplers 120a and 120b may not be coupled to one or more of the transducers 104a-c and the base 106 (e.g., In this configuration, the fin couplers 120a and 120b couple the base 106 and the transducers 104a-c to the fins 108a and The movement of the fins 108a and 108b can be influenced differently than the manner in which the movement of the fins 108a and 108b is influenced.

[0154] For purposes of this specification, a fin coupler assembly includes at least one fin (108a and / or 108b) are connected to at least one fin coupler (120a and / or 120b). Embodiments are contemplated in which more fin couplers and fins are coupled together. For example, in an embodiment, the fin coupler assembly may be, for example, two (120a and 120b, as shown), having two fins (108a and 108b) joined by three, four, five, six or more fin couplers. The fin coupler assembly can have coupling elements used to couple the fins to the fin coupler. These coupling elements may be formed as components of either or both the fin and / or the fin coupler, or the entire fin coupler assembly may be molded. Examples of coupling elements include recesses, tabs, pins, threaded joints, segments for use by brazing, soldering, or welding, fasteners, adhesives, etc.

[0155] The base 106 is the base of the fin sensor 102 to which the fins are coupled. In an embodiment, the base 106 can limit the movement of the fingers 108a and 108b. The base 106 has openings in which the fins 108a and 108b are positioned, and the fins 108a and 108b have upper 153 and lower 155 elements.

[0156] In an embodiment, the base 106 is configured such that the base 106 acts as a conduit element and the side of the base 106 (In some cases, the lower 155 side in the illustrated embodiment) conforms to the conduit 110 so as to be exposed to fluid flowing through the conduit during operation.

[0157] In an embodiment, the base 106 may be or may include a plate. In an embodiment, the plate is less than or equal to the thickness of the material defining the wall of the conduit 110. It may be a plate having a greater thickness (or hardness). In embodiments, the plate may be thicker in certain parts of the plate and thinner in other parts. For example, the center of the plate may be thinner than the area where the plate is coupled to the conduit, and ... The center of the plate may be thinner than the edge of the plate adjacent the conduit 110 at the cross axis 131, and the center of the plate relative to the cross axis 131 may be thinner than the edge of the plate adjacent the conduit 110 at the cross axis 131. The thickness of the plate may be greater than the edge of the port, and the thickness of the plate may be greater than the edge of the port adjacent the conduit at the intersecting axis 131. An increase or decrease from at least the edge of the plate to the center of the plate at the cross axis 131 151, 152, 153, 154, 155, 156, 157, 158, 159, 160, 161, 162, 163, 164, 165, 166, 167, 168, 169, 170, 171, 172, 173, 174, 175, 176, 177, 178, 179, 180, 181, 182, 183, 184, 185, 186, 187, 188, 189, 190, 191, 192, 193, 194, 195, 196, 197, 198, 199, 200, 2000 It can be.

[0158] The base coupler 116 is required to couple the base 106 to the environment in which the fin sensor 102 is used. For example, a base coupler 116 may be used to couple the base 106 of the fin sensor 102 to a The base 106 may be coupled to a location where the flow is to be measured, such as the conduit 110. A base coupler 116 may couple the base 106 to the conduit along the periphery of the base 106. The base 106 may be, for example, a fused By one or more of the following means: welding, brazing, adhesive bonding, or mechanical interlocking. The base coupler 116 may be coupled to the base coupler 116 in any manner known in the art. The base 106 may be formed as a unitary component with the base coupler 116 .

[0159] The balance rib 118 partially limits the deflection of the base 106 at a specific location of the base 106. The balance rib 118 may be an elongated member. The balance rib 118 may be constructed from a material having sufficient rigidity to limit movement, such as vibration and / or oscillatory motion. The balance rib 118 may be a fin at a perpendicular axis 151 relative to the conduit 110. This can help eliminate net movement of the sensor 102. The balance rib 118 may be coupled to one or more of the base 106, the conduit 110, and the base coupler 116. In an embodiment, the balance rib 118 is directly coupled to at least one of the fins 108a and 108b. However, in other embodiments, the balance rib 118 is not coupled to the fins 108a and 108b. In various embodiments, the balance ribs 118 may be offset from the base 106 at several locations along the base 106, such as a location along the base that includes at least a center of the base 106, a location along the base 106 that represents a portion of the center of the base 106 on the cross-axis 131 along a portion of the flow axis 141, etc. In an embodiment, the balance rib 118 may be coupled to the base 106. The length of the base 106 may extend or substantially extend along the length of the base 106. The total length of the base 106 or the length of the base 106 not limited by the base coupler 116. The couplers 116 are equidistant from the portions of the fins that protrude through the base 106 along the intersecting axis 131. In some cases, the intersecting axis 131 may be connected to the base plate at a position By disposing balance ribs 118 between the fin projections at equal distances from the projections, , the balance rib 118 can force the fin to rotate along a rotation point at or substantially near the edge of the base 106 or a point at which the base 106 is unconstrained. This is because the fin has no net vertical axis 151 motion and therefore no circumferential movement. It is possible to have no reactive movement of the structure.

[0160] In an embodiment, where the balance rib 118 is symmetrical about its length around the centerline 198, the balance rib 118 has a centerline 198 that represents the center of the longest length of the balance rib 118. Although shown in Figure 1 as a dashed line visible on the surface, the center line may be That is, the center of mass of each cross section defined by the plane of the transverse axis 131 and the perpendicular axis 151 is inside the balance rib 118. In an embodiment, the balance rib 118 has a centerline 198 The balance ribs 118 may be coupled to the fin sensor 102 so as to be parallel or substantially parallel to the flow axis 141. In an embodiment, the balance ribs 118 may be uniformly spaced about the centerline 198 along the flow axis 141. In another embodiment, the balance rib 118 may have a thickness that varies around the centerline 198 along the flow axis 141 and / or varies along the flow axis 141 itself within the cross-axis 131. For example, in an embodiment, the thickness of the slit 194 may vary from 0.1 mm to 0.5 mm. The thickness of at least one end of the balance rib 196 within the cross axis 131 is about a centerline 198. In another embodiment, the thickness of at least one end of the balance rib 196 within the cross axis 131 about the center line 198 may be greater than the thickness of the central portion of the balance rib 197 within the cross axis 131 about the center line 198. The thickness is less than the thickness of the central portion of the balance rib 197 within the intersecting axis 131 about the centerline 198. It can be small.

[0161] Embodiments are contemplated in which a balanced base assembly is formed. The balanced base assembly can include at least the base 106 and balance ribs 118. In various embodiments, the balanced base assembly can further include fins 108a and 108b. Additionally, the base 106 can be configured to be a variable base 306, as shown in FIG. 3 and generally described herein. In embodiments, this balanced base can include a balanced base 306 that is rotatable relative to the base 106. The sensor assembly may be a component of the fin sensor 102.

[0162] The transducers 104a-c drive and / or measure the movement of the fins 108a and 108b. Although three transducers are shown in the figure, any number of transducers can be used. In the embodiment shown in FIG. 1, an upstream transducer 104a is used to measure the upstream vibration of the relative motion between the first fin 108a and the second fin 108b. In the embodiment shown in FIG. 1, the driving transducer 104b is a A centrally located protrusion of the protrusion 114a of the first fin 108a and / or A segment of the protrusion 114a and a centrally located protrusion 114b of the second fin 108b or protrusion 114b The transducer vibrates the segments of the flow axis 141 along the flow axis. In other embodiments, the driving transducer 104b acting as a driver can drive the base 106 or the more prominent of the fins 108a and 108b. In another embodiment, the driving transducer 104b is disposed inside the base 106 and is connected to one or more of the base 106 and / or the fins. At least one of the actuators 108a and 108b may be vibrated. In one embodiment, the downstream transducer 104c is a sensing transducer that measures the downstream vibration of the relative motion between the first fin 108a and the second fin 108b. The phase difference or time delay between the upstream and downstream vibrations can be measured to yield the mass flow rate of the fluid flowing through and / or around the fins. In another embodiment, a command signal from the drive transducer 104b can be used instead of or in addition to the vibration response measured upstream or downstream to determine the phase difference. The transducers 104a-c are It can also be used to drive and obtain measurements that can be used with known techniques to determine density and / or viscosity. Combining these measurements can result in volumetric flow rate. Methods for these determinations are well known in the art.

[0163] In an embodiment, the transducers 104a-c are coupled to the fin protrusions 114a and 114b. The fin projections 114a and 114b may have different segments for coupling the transducers. For example, in an embodiment, each of 114a and 114b may have three segments. Each of the transducers 104a-c may have segments, with the segments optionally having complementary faces facing each other between the fin projections 114a and 114b. Each of the transducers 104a-c may be coupled to one of the corresponding segments of the fin projections 114a and 114b (the corresponding segments optionally facing each other within the intersecting axis 131). In this embodiment, three transducers The transducers 104a-c may be aligned with one another in the flow axis 141 (at least when the fin sensor 102 is not operating). In this embodiment, the transducers 104a-c may be coupled to the fins 108a and 108b at locations located on a side of the base 106 that faces the side of the base 106 that has the submerged portions of the fins 108a and 108b.

[0164] In various embodiments, the fin couplers 120a and / or 120b can couple the fins 108a and / or 108b on the submerged side 342 or on the outer side 344. For example, in embodiments, the fin couplers couple the fins 108a and 108b on the outer side by coupling the fin projections 114a and 114b, e.g., by coupling segments representing the fin projections 114a and 114b. The fin couplers 120a and / or 120b may couple the fins 108a and / or 108b below 155 and below the area on the fins 108a and / or 108b to which one or more of the transducers 104a-c are coupled. and / or may be coupled to the fin at a location above 153. The couplers 120a and / or 120b may be arranged such that the fins 108a and 108b are coupled to the transducers 104a-c. and / or at a location closer to the base 106 than the location on the outside 344 of the base 106. In an embodiment, the fin couplers 120a and / or 120b are coupled to the fins on the outside 344 of the base 106 at a location closer to the location on the fins 108a and / or 108b to which the transducers 104a-c are coupled than to the base 106. In an embodiment in which the fin couplers 120a and / or 120b are coupled to the fins 108a and / or 108b on the outside 344 of the base 106, it can be appreciated that in an embodiment in which the fin couplers 120a and / or 120b are coupled to the fins 108a and / or 108b on the outside 344 of the base 106, the fin couplers 120a and / or 120b may be outside of the fluid flow, which may reduce the possibility of the fin couplers 120a and / or 120b affecting the flow profile and / or being susceptible to erosion and / or corrosion. In embodiments in which the fin couplers 120a and / or 120b are coupled to the fins 108a and / or 108b on the outside 344 of the base 106, the fin couplers 120a and / or 120b may still induce mode splitting and / or may still induce more curl in the OOP mode.

[0165] The meter electronics 112 is a set of electronic logic circuits that determines the flow characteristics from the flow measurements. Meter electronics 112 is not shown in FIG. 1, but the configuration and coupling of meter electronics is well known in the art. Meter electronics 112 may be implemented as logic circuits representing processing elements. logic circuits representing paths, memory, logic circuits for sending and receiving data, and communication circuits for coupling to sensors, drivers, computing devices, other meter electronics 112, etc. The meter electronics 112 may include a processor that may store the The meter electronics 112 may execute received commands to send drive signals, receive sensor data (e.g., from sensing transducers such as the upstream transducer 104a and the downstream transducer 104c), determine flow characteristics, and / or transmit raw or determined data to an external computing device, sensor, or the like. The transducer 104b may be used to determine and / or transmit data representative of, for example, mass flow rate, density, volumetric flow rate, etc. The meter electronics 112 uses the driven transducer 104b to 4. The meter electronics 112 may be configured to drive or transmit instructions to drive the fins 108a and 108b at different frequencies, phases, and / or in different modes using a computer system 400 of FIG. 4. In an embodiment, the meter electronics 112 may be coupled to the base 106 or the fins 108a and 108b, or in some cases, coupled to the exterior 344 of the base 106. In another embodiment, the meter electronics 112 may be a device external to the fin sensor 102. The meter electronics 112 may be an embodiment of the computer system 400 of FIG.

[0166] In an embodiment, one, any combination, or all of the electronic components are external to the fluid flow. The electronic elements may include one, any combination, or all of the transducers 104a-104c and / or the meter electronics 112.

In a straight conduit, this axis may be defined by the center of the interior of the conduit along a line representing the fluid flow. Upstream direction 143 is defined as the upstream direction along flow axis 141 in which the flow fluid flows. Downstream direction 145 is defined as the downstream direction along flow axis 141 in which the flow fluid flows.

The vertical axis 151 is perpendicular to the flow axis 141 and the cross-axis 131. The upward direction 153 is a line that bisects the center of the conduit 110 along the vertical axis 151 from the center of the conduit 110 to the base 106. Downward direction 155 is defined as the direction from base 106 to the center of conduit 110 along vertical axis 151.

[0169] The cross axis 131 is an axis that is parallel or substantially parallel to the base 106 (or may be parallel to a line representing the average distance of the base 106 from the center of the conduit 110 if the base is curved) and perpendicular to the fluid flow, the cross axis 131 being perpendicular to the flow axis 141 and the normal axis 151. The first direction 133 and the second direction 135 are in opposite directions along the cross axis 131. In the illustrated embodiment, the first direction 133 is defined by the normal axis 151 and the cross axis 131 from a perspective facing the downstream direction 145. If one were to look at a cross-section of the conduit 110, the direction would be to the left of the conduit 110. The directions and reference axes are seen to be relative to the fin sensor 102 and the flow therethrough, but the direction and reference axes, the disclosed embodiments of the particular elements of the fin sensor meter merely refer to the relative positions, couplings, arrangements, and configurations of those elements as described with respect to the fin sensor 102 and the reference axes. It should be understood that the balance rib 118 may be considered as an independent element having a direction and a reference axis in order to illustrate the flow of the balance rib 118 separately from the overall flow therethrough. If the thickness varies along the flow axis, the variation is relative to the balance rib 118 itself in the figure. and may not be to the flow or the flow sensor 102 in general. The disclosed embodiments of the fin sensor 102 and its elements are primarily designed to be, for example, manufactured or The relative position, coupling, arrangement, and configuration of the fin sensor 102 when installed and not subjected to flow It should be understood that these criteria represent the same.

[0171] 2B shows a perspective view of an embodiment of a fin coupler assembly 200b having a strip-like fin coupler 220b. The strip-like fin coupler 220b can be an embodiment of the fin couplers 120a and / or 120b. In alternative embodiments, the flat portion of the strip may be parallel to the plane defined by the cross axis 131 and the flow axis 141, for example when there is no flow in the conduit, may be parallel to the plane defined by the vertical axis 151 and the cross axis 131, or may have a helically twisted portion.

[0174] FIG. 3 illustrates a fin sensor 302 having a variable base 306 in a balanced base assembly. 1 is a cross-sectional view of an embodiment of a flow sensor system 300 having a cross-sectional view of a plane defined by a normal axis 151 and an intersecting axis 131. The flow sensor system 300 has The variable base 306, the first fin 308a, the second fin 308b, the submerged side 342, and the outer side 344. The flow sensor system 300 may include a fin sensor 302 having a fin sensor 302. The variable base 306, the first fin 308a, and the second fin 308b correspond to the fin sensor system 100, the fin sensor 102, the base 106, the first fin 108a, and the second fin 108b of FIG. The variable base 306 may have a first rigid portion 310, a second rigid portion 312, and a flexible portion 314. The reference directions and axes correspond to the diagram of FIG. It should be understood that the images shown may not be to scale and that embodiments having different relative dimensions are contemplated.

[0175] In the illustrated embodiment, the flexible portion 314 is located at the center of the flexible base 306 (the flexible portion at the cross axis 131). The flexible portion 314 is located at the center of the variable base 306, and the first and second rigid portions 310 and 312 of the variable base 306 are located on sides of the variable base 306 proximate where the variable base 306 is coupled to the conduit. In various embodiments, the transition between the flexible portion 314 and the rigid portions 310 and 312 increases in stiffness from the center of the variable base 306 to the respective edges of the first and second sides of the variable base 306. The transition may be smooth at the point where the variable base 306 is inserted, or the transition may be from the center of the variable base 306 to the center of the variable base 306. It will be appreciated that this can occur in a stepwise manner with an increase in hardness within the block up to the respective edges of the respective first and second sides. In an embodiment, this can be achieved by making the flexible portions thinner and the rigid portions thicker, possibly by cutting out portions of the base 106. The difference in flexibility and hardness can be facilitated by forming the base 106 as a variable base 306 of varying thicknesses. In another embodiment, the flexibility and hardness can be varied by using different materials or alloys along the cross axis 131, harder at the hard portions 310 and 312 and softer at the flexible portion 314.

It will be appreciated that the fins 108a and 108b may not necessarily represent separate flexible portions as shown (balance ribs 118 may provide additional stiffness when coupled to sensor 302). In an embodiment, the portion of variable base 306 between the two fins 108a and 108b (along cross axis 131) may be The flexible portion 314 and the rigid portions 310 and 312 may be softer than the portions of the variable base 306 between each of the fins 108a and 108b (at the cross axis 131) and the edges of the variable base 306. In an embodiment, the flexible portion 314 and the rigid portions 310 and 312 may be arranged to support at least one of the fins 108a and 108b near the cross axis 131. In this case, the balance rib 118 may be formed by bonding to the edge of the variable base 306 rather than to the balance rib 118 .

[0177] In an embodiment in which the variable base 306 does not have a balance rib 118 and the fin sensor 102 is variable Embodiments are contemplated having balance ribs 118 that do not have a base 306. For example, embodiments may be provided that are consistent in thickness and material (such as the plate's ability to withstand shocks caused by coupling with the environment, such as the conduit 110). It is possible to have a base 106 that has uniform properties by itself, such as with variation, and still 1 and 2. The base 106 may have a balance rib 118. In this embodiment, the base 106 may be a uniform thin plate.

The immersion side 342 is , portions of the fins 108a and 108b and / or the base 106 are exposed to the flowing fluid being measured. Outer side 344 represents the side of base 106 on which fin protrusions 114a and 114b are disposed and which may potentially be coupled to a transducer.

[0179] In an embodiment, the fin projections 114a and 114b can have segments that, in some cases, each protrude through an opening in the base 106 when the fin sensor 302 is assembled. Fin projections 114a and 114b may have different segments for coupling transducers. For example, in an embodiment, each of 114a and 114b may have three segments, and the segments may be optionally coupled to fins. The transducers 104a to 104c have complementary surfaces facing each other between the projections 114a and 114b. Each may be coupled to one of the corresponding segments of the fin projections 114a and 114b (the corresponding segments may be opposed to each other within the intersecting axis 131). In an embodiment, the three transducers 104a-c may be aligned with each other in the flow axis 141. (At least when the fin sensor 102 is not operational). In this embodiment, The transducers 104a-c are arranged such that the fins 108a and 108b are disposed at positions located on the outer side 344 of the base 106. may be coupled to

In an embodiment, a balanced base assembly may be manufactured using one or more fin couplers 120a and / or 120b to manufacture a combined balanced base and fin coupler assembly. In some embodiments, the balanced base assembly may be a component of the fin sensor 102.

[0211] Step 802 may optionally include removing the transducers 104a-c, the first and second fins 108a and 108b, the meter electronics 112, the balance ribs 118, the base coupler 116, and the first and second The objective of the present invention is to form the fin couplers 120a and 120b of the above-mentioned components. The manufacturing methods used are well established in the art, such as 3D printing, molding, bonding of individually formed components, etc.

[0212] Step 804 is to form at least one base 106. The base 106 may be a flat or substantially flat member having little thickness relative to the area of ​​its larger surface. In an embodiment, the base 106 may be formed thin and / or have various Alternatively, the base 106 may be formed with a uniform hardness. For example, the base 106 may be formed such that the center of the deformable base 306 (which is the center of the cross axis 131) is less hard than the edges (of the deformable base 306 at the cross axis 131). The variability can be achieved by forming the base 106 by molding to produce a variable base 306 that has a center (along the intersecting axis 131) that is thinner (less material) than the edges (of the variable base 306 at the intersecting axis 131). In another embodiment, the variability can be achieved by removing or even replacing portions of the base 106. When cut, the center (along the transverse axis 131) is thinner than the edges (of the variable base 306 within the transverse axis 131). This can be achieved by making the base 106 a variable base that is lighter (less material). In another embodiment, the base 106 is configured such that the center (along the intersecting axis 131) of the variable base 306 is (along the intersecting axis 131). The variable base 306 may be made of a different material along the cross axis 131 so that the material is softer than the edge of the variable base 306 within the cross axis 131. The base may be a variable base 306.

[0213] Step 806 is to form the balance rib 118. The balance rib 118 is formed by an elongated portion.

In an embodiment, if the balance rib 118 is symmetrical about at least one axis along its length, for example about the intersecting axis 131 about the centerline 198, the balance rib 118 may be symmetrical about the centerline 198 that represents the center of the longest length of the balance rib 118. The balance rib 118 may have a length and a circumference of the centerline 198. For example, in an embodiment, the thickness of the slit 194 may vary from 0.1 mm to 0.2 mm. The thickness of at least one end of the balance rib 118 in the differential shaft 131 is about the centerline 198. The thickness of the balance rib 118 at least at one end within the cross axis 131 about the centerline 198 may be greater than the thickness of the central portion of the balance rib 197 within the cross axis 131. In another embodiment, the thickness of the balance rib 118 at least at one end within the cross axis 131 about the centerline 198 may be greater than the thickness of the central portion of the balance rib 197 within the cross axis 131. The thickness is less than the thickness of the central portion of the balance rib 197 within the intersecting axis 131 about the centerline 198. It's okay if it's small.

[0214] Step 808 is to couple the balance rib 118 to the base 106. The balance rib 118 may be coupled to the base at a central location of the base at the intersecting axis 131, and may optionally In embodiments where the base 106 has fins 108a and 108b coupled to the base 106 or will have fins 108a and 108b coupled to the base 106, the balance rib 118 may be coupled 131 and 132. The first fin 108a may be coupled to the base 106 between the fins 108a and 108b arranged along the intersecting axis 131, and in some cases, the second fin 108b may be coupled to the base 106 between the fins 108a and 108b arranged along the intersecting axis 131, and in some cases, the first fin 108a may be coupled to the base 106 between the fins 108a and 108b arranged along the intersecting axis 131. The assembly formed when the balance rib 118 is coupled to the base 106 (or the variable base 306) is , can be considered as a balanced base assembly for the fin sensor 102. , the balance rib 118 is oriented such that the centerline 198 is parallel or substantially parallel to the flow axis 141. The balance rib 118 may be coupled to the fin sensor 102. In an embodiment, the balance rib 118 may have a uniform thickness about the centerline 198 along the flow axis 141. In another embodiment, the balance rib 118 may have a thickness that varies along the flow axis 141 about the centerline 198 of the cross axis 131. For example, in an embodiment, the thickness of at least one end of the balance rib 118 within the cross axis 131 about the centerline 198 may vary along the flow axis 141 about the centerline 198. For example, in an embodiment, the thickness of the central portion of the support rib 198 may be greater than the thickness of the central portion of the support rib 197. The thickness of at least one end of the balance rib 118 within the intersecting axis 131 may be less than the thickness of a central portion of the balance rib 197 within the intersecting axis 131 within the centerline 198 .

[0215] Step 810 optionally aligns the balanced base assembly with the fins 108a and 108b (if In some cases, the fin sensor 102 is formed by coupling a fin projection 114a and 114b (and optionally a balance rib 118 between fins 108a and 108b on the base 106) to the transducers 104a-c, the meter electronics 112, the base coupler 116, and / or the first and second fin couplers 120a and 120b. In embodiments, the fin projections 114a and 114b can have segments, and the segments, in some cases, extend beyond the base projection 114a and 114b when the fin sensor 302 is assembled. Each of the transducers 104a-c protrudes through an opening in the fin projections 114a and 114b. In an embodiment, the transducers 104a-c may be coupled to the fin projections 114a and 114b. The fin projections 114a and 114b may have different segments for coupling the transducers. For example, in an embodiment, each of the fin projections 114a and 114b may have three segments, and the segments may be Each of the transducers 104a-c may have complementary faces that face each other between the fin projections 114a and 114b. (corresponding segments may be opposed to each other within the cross axis 131) In this embodiment, the three transducers 104a-c are aligned along the flow axis 141. may be aligned with each other (at least when the fin sensor 102 is not in operation). In this embodiment, the transducers 104a-c are disposed on the submerged portions of the fins 108a and 108b. The fins 108a and 108b may be coupled to the fins 108a and 108b at a location located on a side of the base 106 opposite the side of the base 106 having the fins 108a and 108b. The meter electronics 112 may be coupled to the base 106 or the fins 108a and 108b, or in some cases, may be coupled to the outside 344 of the base 106.

[0216] In an embodiment, each step of the method shown in Figure 8 is a separate step. Although shown as separate steps in FIG. 8, steps 802-810 are separate processes.

This may be repeated any number of times in any combination and order, such as looping continuously to maintain monitoring.

[0217] 9 illustrates a flow chart of an embodiment of a method 900 for fabricating a balanced base and fin coupler assembly of the fin sensor 102. The method steps of the method 900 are presented by way of an embodiment with reference to elements presented in other figures and the description of other figures. All capabilities, structures, relative connections, and arrangements of these elements disclosed in the other figures and the description of other figures are contemplated for purposes of performing these steps. In an embodiment, the balanced base assembly may be a component of the fin sensor 102.

The manufacturing methods used to form these components are established in the art, such as 3D printing, molding, bonding of individually formed components, etc.

[0219] Step 904 is to form at least one base 106. The base 106 may be a flat or substantially flat member having little thickness relative to the area of ​​its larger surface. In an embodiment, the base 106 may be formed thin and / or have various Alternatively, the base 106 may be formed with a uniform hardness. The center of the cross axis 131 is less stiff than the edge of the variable base 306 at the cross axis 131. The variability can be achieved by forming the base 106 by molding to produce a variable base 306 that has a center (along the intersecting axis 131) that is thinner (less material) than the edges (of the variable base 306 at the intersecting axis 131). In another embodiment, the variability can be achieved by removing or even replacing portions of the base 106. When cut, the center (along the transverse axis 131) is thinner than the edges (of the variable base 306 within the transverse axis 131). This can be achieved by making the base 106 a variable base that is lighter (less material). In another embodiment, the base 106 is configured such that the center (along the intersecting axis 131) of the variable base 306 is (along the intersecting axis 131). The variable base 306 may be made of a different material along the cross axis 131 so that the material is softer than the edge of the variable base 306 within the cross axis 131. The base may be a variable base 306.

[0220] Step 906 is to form the balance rib 118. The balance rib 118 is an elongated portion. The base 106 may be made of any material known in the art sufficient to at least partially limit movement of the base 106 using any standard manufacturing method. In an embodiment, if the balance rib 118 is symmetrical about at least one axis along its length, for example about the intersecting axis 131 about the centerline 198, the balance rib 118 may be symmetrical about the centerline 198 that represents the center of the longest length of the balance rib 118. The balance rib 118 may have a length and a circumference of the centerline 198. For example, in an embodiment, the thickness of the slit 194 may vary from 0.1 mm to 0.2 mm. The thickness of at least one end of the balance rib 118 in the differential shaft 131 is about the centerline 198. The thickness of the balance rib 118 at least at one end within the cross axis 131 about the centerline 198 may be greater than the thickness of the central portion of the balance rib 197 within the cross axis 131. In another embodiment, the thickness of the balance rib 118 at least at one end within the cross axis 131 about the centerline 198 may be greater than the thickness of the central portion of the balance rib 197 within the cross axis 131. The thickness is less than the thickness of the central portion of the balance rib 197 within the intersecting axis 131 about the centerline 198. It's okay if it's small.

[0221] Step 908 is to couple the balance rib 118 to the base 106. The balance rib 118 may be coupled to the base at a central location of the base at the intersecting axis 131, and may optionally In embodiments where the base 106 has fins 108a and 108b coupled to the base 106 or will have fins 108a and 108b coupled to the base 106, the balance rib 118 may be coupled 131 and 132. The first fin 108a may be coupled to the base 106 between the fins 108a and 108b arranged along the intersecting axis 131, and in some cases, the second fin 108b may be coupled to the base 106 between the fins 108a and 108b arranged along the intersecting axis 131, and in some cases, the first fin 108a may be coupled to the base 106 between the fins 108a and 108b arranged along the intersecting axis 131. The assembly formed when the balance rib 118 is coupled to the base 106 (or the variable base 306) is , can be considered as a balanced base assembly for the fin sensor 102. , the balance rib 118 is oriented such that the centerline 198 is parallel or substantially parallel to the flow axis 141. The balance rib 118 may be coupled to the fin sensor 102. In an embodiment, the balance rib 118 may have a uniform thickness about a centerline 198 along the flow axis 141. In another embodiment, the balance rib 118 may have a thickness that varies along the flow axis 141 about a centerline 198 of the cross axis 131. For example, in an embodiment, the thickness of at least one end of the balance rib 118 about the cross axis 131 may vary from the thickness of the balance rib 118 about the centerline 198 to the thickness of the balance rib 197 about the centerline 198. The thickness of the balance rib 118 at least at one end within the cross axis 131 about the centerline 198 may be greater than the thickness of the central portion of the cross axis 131. For example, in an embodiment, the thickness of at least one end of the balance rib 118 within the cross axis 131 about the centerline 198 may be greater than the thickness of the central portion of the cross axis 131. It may be less than the thickness of the central portion of the balance rib 197 within the central intersecting axis 131.

[0222] Step 910 is to form at least one fin coupler (e.g., first and second fin couplers 120a and / or 120b). Manufacturing methods for producing elements such as fin couplers are well known in the art, such as molding, extrusion, and other methods. Fin couplers can be formed, for example, from metal or other composite materials. At least one fin connector may be, for example, a rod, strip, or brace bar. In an embodiment, the at least one fin coupler may be formed in a variety of shapes. The fins 108a and 108b may be formed as a single piece (step 702). a separate step of forming fins 108a and 108b, and / or at least one In an embodiment, the at least one fin coupler may be connected to the fins 108a and 108b, e.g., by one or both ends of the at least one fin coupler, eliminating the need for a separate step of coupling the at least one fin coupler to the fins 108a and 108b. By one or more coupling elements configured to facilitate and / or more effectively couple In another embodiment, one or more of the fins 108a and 108b may be formed with at least At least one fin coupler may be easily and / or more efficiently attached to fins 108a and 108b. In yet another embodiment, both the at least one fin coupler and the fins 108a and 108b can have corresponding or complementary coupling elements to couple the at least one fin coupler to the fins 108a and 108b, respectively. In an embodiment, the at least one fin coupler may be two, three, four, five, six, or any other number of fin couplers.

[0223] Step 912 is to couple at least one fin coupler to the first and second fins 108a, 108b. In embodiments in which one or more of the fins 108a and 108b and at least one fin coupler have coupling elements, at least one fin coupler and the fin The connectors 108a and 108b may be coupled at and / or by a coupling element. Any coupling method is contemplated, such as welding, brazing, soldering, adhesive bonding, plastic molding or fusing, complementary physical or mechanical connectors, etc.

[0224] Step 914 is to bond the fins 108a and 108b to the base 106. The fins 108a and 108b may be bonded to the base 106 in any manner, for example, by molding them together. The base 106 may be formed with fin projections 114a and 114b and joined by adhesive, welding or brazing, and other methods known in the art. The casing has an opening through which the casing can be exposed and a bond established by standard bonding methods such as adhesive bonding, welding, and brazing.

[0225] Step 916 optionally aligns the balanced base assembly with the fins 108a and 108b (if In some cases, the base 106 may have a balance rib 118 between the fins 108a and 108b on the base 106, which couples the transducers 104a-c, the meter electronics 112, and / or the base coupler 116. In an embodiment, the fin projections 114a and 114b may have segments, which may optionally include fins. Each of the transducers 104a-c may protrude through an opening in the base 106 when the sensor 302 is assembled. In an embodiment, the transducers 104a-c may be coupled to the fin protrusions 114a and 114b. The fin projections 114a and 114b may have different segments for coupling the transducers. For example, in an embodiment, each of the fin projections 114a and 114b has three Each of the transducers 104a-c may have a fin segment, with the segments possibly having complementary faces facing each other between the fin projections 114a and 114b. Each transducer 104a-c may be coupled to one of corresponding segments of the projections 114a and 114b (which corresponding segments may be opposed to one another in the cross axis 131). In this embodiment, the three transducers 104a-c may be aligned with one another in the flow axis 141 (at least when the fin sensor 102 is not operating). In this embodiment, the transducers 104a-c may be coupled to the fins 108a and 108b at locations located on a side of the base 106 that faces the side of the base 106 that has the submerged portions of the fins 108a and 108b.

For example, and bonding the fins 108a and 108b to the base 106. may be performed in any order relative to one another, and the balanced base assembly may be formed before, during, or after the fin coupler assembly is formed.

[0227] In an embodiment, each step of the method shown in Figure 9 is a separate step. Although shown as separate steps in FIG. 9, steps 902-916 are separate steps. In other embodiments, the method shown in FIG. 9 may include all of the above steps. 9 may be performed in a different order, and / or may have other steps in addition to or instead of those listed above. A subset of the steps listed above as part of the method illustrated in FIG. The steps of the method 900 can be used to form a method of its own. This may be repeated any number of times in any combination and order, such as looping continuously to maintain monitoring.

[0228] [Comparison] 10-11 provide a comparison illustrating certain advantages of embodiments of Applicant's features presented herein.

[0229] FIG. 10 illustrates fin couplers 120a and 120b driven in in-phase (IP) and out-of-phase (OOP) modes. 10 shows a comparison 1000 of an embodiment of the fin sensor 102 with and without fin 120b. Fin sensors 102a and 102b are embodiments of fin sensor 102 without and with fin couplers 120a and 120b, respectively. Comparison 1000 compares a first row 1042 with a second row 1043. It has a row 1044 , a first image 1052 , a second image 1054 , a third image 1056 , and a fourth image 1058 .

[0230] The first row 1042 is an image representing the fin sensor 102a without the fin couplers 120a and 120b. , where a first row 1042 has a first image 1052 and a second image 1054. The first image 1052 shows an embodiment of the fin sensor 102a without the fin couplers 120a and 120b, where the fin sensor 102a is driven in an in-phase mode. The second image 1054 shows an embodiment of the fin sensor 102a driven in an out-of-phase mode. 10 shows an embodiment of a fin sensor 102a. At point 1055, it can be seen that the out-of-phase mode fin shows little curl and remains essentially flat. It can be seen that there is little frequency separation between the in-phase and out-of-phase modes, both driven with the same force, and their response frequencies approach substantially the same value. This lack of separation between vibrational modes can result in coupling between the driven and natural modes, contaminating the intended excitation geometry such that calibration and measurement errors can occur.

[0231] A second row 1044 of images represents fin sensor 102b having fin couplers 120a and 120b. The second row 1044 has a third image 1056 and a fourth image 1058. The third image 1056 shows an embodiment of a fin sensor 102b having fin couplers 120a and 120b, where the fin sensor 102b is driven in an in-phase mode. The second image 1054 shows an embodiment of a fin sensor 102b having fin couplers 120a and 120b driven in an out-of-phase mode. 10 shows an embodiment of the fin sensor 102b with fin couplers 120a and 120b. At point 1059, it can be seen that the out-of-phase mode exhibits significant curl and produces greater amplitude, frequency, and phase resolution. This produces significant frequency separation between the in-phase and out-of-phase modes, as both are driven with the same force, and the out-of-phase mode fin sensor 102b produces frequencies 20% higher than those produced by the in-phase mode in this embodiment. This frequency separation between the in-phase and out-of-phase modes can at least limit coupling between the in-phase and out-of-phase modes, potentially allowing for better measurement and calibration. The increased curl can allow the fin sensor 102b to better couple the fins to the flowing medium and induce a Coriolis response, possibly similar to a typical Coriolis mass flowmeter.

[0232] FIG. 11 shows the balance rib 118 with and without in undeformed and deformed positions. 11 shows a comparison 1100 of fin sensor 102 embodiments with and without balance ribs 118. Fin sensors 102c and 102d are fin sensor 102 embodiments with and without balance ribs 118, respectively. The comparison 1100 has a first row 1142, a second row 1144, a first image 1152, a second image 1154, a third image 1156, and a fourth image 1158.

[0233] A first row 1142 is a row of images representing a fin sensor 102c without balance ribs 118, and the first row 1142 has a first image 1152 and a second image 1154. The first image 1152 shows an embodiment of the fin sensor 102c without balance ribs 118, where the fin sensor 102c is undeformed. A second image 1154 shows an embodiment of a fin sensor 102c without balance ribs 118 in a deformed position. At points 1155a and 1155b, the axis of rotation of fins 108a and 108b can be seen to be at the edge of base 106. The resulting motion of the sensor assembly When the sensor assembly is in the vertical axis 151, a net motion is generated through the sensor assembly to counter the imbalance. It will be appreciated that this raises the sensor assembly relative to the support structure to which the fin sensor 102c is coupled.

[0234] A second row 1144 is a row of images depicting a fin sensor 102d having balance ribs 118, and second row 1144 has a third image 1156 and a fourth image 1158. The third image 1156 shows an embodiment of a fin sensor 102d having balance ribs 118, where the fin sensor 102d is in a non-deformed position. A fourth image 1154 shows an embodiment of a fin sensor 102d having balance ribs 118, where the fin sensor 102d is in a deformed position. At points 1159a and 1159b, the axis of rotation of the fins 108a and 108b can be seen to be at the attachment of the fins 108a and 108b to the base 106. The resulting movement of fins 108a and 108b produces no net motion about a vertical axis 151 through the center of the sensor assembly, providing balance and allowing fin sensor 102d to be coupled It will be appreciated that this does not move the sensor assembly relative to the supporting structure on which it is mounted. In embodiments, this may not provide a net movement of the fins (or tines) in the vertical direction. It will be appreciated that in some embodiments, the fins 108a and 108b of the fin sensor 102d can rotate about their respective center points (at 1159a and 1159b, respectively).

[0235] FIG. 12 illustrates the outer 344 of the base 106 driven in in-phase (IP) and out-of-phase (OOP) modes. 1. Fin sensor 102 implementation with and without fin couplers 120a and 120b 12 shows a comparison 1200 of embodiments of the fin sensor 102 without and with the fin couplers 120a and 120b, respectively. A first row 1242, a second row 1244, a first image 1252, a second image 1254, and a third image 1256. , and a fourth image 1258.

[0236] The first row 1242 is an image representing a fin sensor 102e without fin couplers 120a and 120b. , where a first row 1242 has a first image 1252 and a second image 1254. The first image 1252 shows an embodiment of the fin sensor 102a without the fin couplers 120a and 120b, where the fin sensor 102a is driven in an in-phase mode. The second image 1254 shows an embodiment of the fin sensor 102a driven in an out-of-phase mode. 12 shows an embodiment of the fin sensor 102a. At point 1255, it can be seen that the out-of-phase mode fin shows little curl and remains essentially flat. It can be seen that there is little frequency separation between the in-phase and out-of-phase modes, both driven with the same force, and their response frequencies approach substantially the same value. This lack of separation between vibrational modes can result in coupling between the driven and natural modes, contaminating the intended excitation geometry such that calibration and measurement errors can occur.

[0237] A second row 1244 of images represents fin sensor 102b having fin couplers 120a and 120b. The second row 1244 has a third image 1256 and a fourth image 1258. The third image 1256 shows an embodiment of a fin sensor 102b having fin couplers 120a and 120b, where the fin sensor 102b is driven in an in-phase mode. The second image 1254 shows an embodiment of a fin sensor 102b having fin couplers 120a and 120b driven in an out-of-phase mode. 1 shows an embodiment of the fin sensor 102b with fin couplers 120a and 120b. This creates significant frequency separation between the in-phase and out-of-phase modes because both are driven with the same force, with the out-of-phase fin sensor 102b generating a frequency 20% higher than that generated by the in-phase mode in this embodiment. This frequency separation between the in-phase and out-of-phase modes can at least limit coupling between the in-phase and out-of-phase modes, potentially allowing for better measurement and calibration.
