Description

Technical Field

[0001] This invention relates to a modular measuring device for determining the density of a measuring medium. Background Technology

[0002] This measuring device is also known as a Coriolis measuring device. To measure the density of a measuring medium, the medium passes through a vibrating tube of the device, which is simultaneously vibrated by an exciter. The resulting vibration is measured. The resulting vibration depends on the density of the measuring medium flowing through the vibrating tube. By comparing the exciter's vibration with the resulting vibration, the density of the measuring medium can ultimately be derived. This comparison uses, for example, the change in phase shift or amplitude between the exciter's vibration and the vibration produced by the vibrating tube.

[0003] However, the resulting vibrations also depend on the temperature of the vibrating tube, which affects the surface moment of inertia of the tube, thus influencing the vibrations produced. Therefore, accurate temperature measurement of the vibrating tube is essential for determining the density of the measured medium with maximum precision.

[0004] In some industrial applications, the measuring medium used requires time-consuming and costly cleaning of the vibratory tube. For such applications, disposable vibratory tubes that can be replaced within the Coriolis measuring device are desirable. However, if the temperature sensor is not removably attached to the vibratory tube, replacing the vibratory tube also means replacing the temperature sensor.

[0005] Furthermore, depending on the industrial application, a predetermined diameter of the vibrating tube is necessary to achieve different flow rates. Therefore, depending on the required flow rate, it is necessary to use different vibrating tubes with different diameters. Summary of the Invention

[0006] Therefore, the object of the present invention is to provide a modular measuring device that can use vibrating tubes of different thicknesses, while being both cost-effective and accurate.

[0007] According to the present invention, this objective is achieved by the modular measuring device according to claim 1.

[0008] A modular measuring device for determining the density of a measuring medium according to the present invention comprises: a support module, a first measuring tube module, and at least one additional measuring tube module. The support module has a housing for detachably securing the measuring tube modules, a non-contact temperature sensor, a main actuator component, and a main sensor component. Each measuring tube module has a limiter complementary to the housing of the support module, a vibrating tube, an auxiliary actuator component complementary to the main actuator component, and an auxiliary sensing component complementary to the main sensor component. Each vibrating tube of the measuring tube module has a different tube diameter, a straight first tube leg, a straight second tube leg, a bent first tube elbow, and a bent second tube elbow. Each first tube leg is connected to a first tube elbow at a main connection point. The first tube elbow is connected to a second tube elbow, and each second tube elbow is connected to a first tube leg at an auxiliary connection point. The main connection point and the auxiliary connection point are located in a corresponding plane of each measuring tube module. These planes are at a corresponding distance from each other, which corresponds to the difference between the corresponding tube diameters. The first and second pipe bends have the same inner or outer radius, such that the centerlines associated with the corresponding vibrating pipes intersect at the first and second intersection points. A non-contact temperature sensor is arranged such that when the measuring tube module is received in the support module, the non-contact temperature sensor points to either the first or second intersection point.

[0009] Based on the modular measuring device according to the invention, different vibrating tubes with different diameters can be used. This allows the use of a corresponding vibrating tube according to the required measurement accuracy. Furthermore, the non-contact temperature sensor enables the determination of the vibrating tube temperature of each vibrating tube in a cost-effective, reliable, and accurate manner. Due to the non-contact temperature measurement, fewer parts of the modular measuring device are used only once, which reduces costs and is environmentally friendly. The specific shape of the different measuring tubes ensures that the temperature sensor is always orthogonal to the surface to be measured on each measuring tube, enabling accurate temperature measurements.

[0010] According to one embodiment of the present invention, a pipe segment is arranged between a first pipe bend and a second pipe bend, the pipe segment connecting the first pipe bend and the second pipe bend.

[0011] According to one embodiment of the present invention, the pipe section is straight.

[0012] According to one embodiment of the invention, the first leg and the second leg extend parallel to each other.

[0013] According to one embodiment of the present invention, the auxiliary exciter component of the measuring tube module is arranged on the measuring tube module along the longitudinal axis. The vibrating tube is symmetrical about the longitudinal axis.

[0014] According to one embodiment of the present invention, the main actuator component includes a coil and the auxiliary actuator component includes a permanent magnet, or the auxiliary actuator component includes a coil and the main actuator component includes a permanent magnet.

[0015] According to one embodiment of the present invention, the auxiliary sensor component is arranged on the first leg or the second leg of the measuring tube module.

[0016] According to one embodiment of the present invention, each measuring tube module has at least two identical vibrating tubes.

[0017] According to one embodiment of the invention, the measuring tube module extends along a longitudinal axis, and the vibrating tube is symmetrical about this longitudinal axis. All measuring tube modules have the same extension length along the longitudinal axis.

[0018] According to one embodiment of the invention, the measuring tube module extends along a longitudinal axis, and the vibrating tubes are symmetrical about this longitudinal axis. All the vibrating tubes intersect at a third intersection point on the longitudinal axis. Attached Figure Description

[0025] Figure 6 It shows Figure 5 An enlarged view of the stacked measuring tube modules shown. Detailed Implementation

[0026] Figure 1A modular measuring device 1 for determining the density of a measuring medium according to the present invention is shown. The modular measuring device 1 includes a support module 10, a first measuring tube module 20, and at least one additional measuring tube module 40, 60. For example, the modular measuring device 1 includes three different measuring tube modules, specifically a first measuring tube module 20, a second measuring tube module 40, and a third measuring tube module 60 (see [link to documentation]). Figures 3 to 6 Of course, the modular measuring device 1 may also have more than three different measuring tube modules. Preferably, the modular measuring device 1 has a control unit 15, which is adapted to process and evaluate the measured values ​​determined by the modular measuring device 1.

[0027] The support module 10 of the modular measuring device 1 has a housing 11 for removably securing the measuring tube modules 20, 40, and 60, a non-contact temperature sensor 12, a main actuator component 13, and a main sensor component 14. The non-contact temperature sensor 12, the main actuator component 13, and the main sensor component 14 are connected to a control unit 15 for control by the control unit 15. The support module 10 is preferably made of corrosion-resistant metal or plastic. The housing 11 is, for example, as shown in the image. Figure 1 The recess shown may be a different design of the receiver 11. The non-contact temperature sensor 12 is, for example, an infrared sensor, a laser system for temperature measurement, or another temperature sensor based on a non-contact measurement method. The temperature sensor 12 is only... Figure 1 The diagram is schematically shown. The main actuator component 13 is, for example, a coil suitable for generating a magnetic field. Actuator component 13 will be discussed in more detail later. Actuator component 11 is schematically shown. Figure 1 The main sensor component 14 is, for example, a coil suitable for detecting magnetic fields. The main sensor component 14 will be discussed in more detail later. Figure 1 The main sensor component 14 is also schematically shown in the diagram.

[0028] like Figures 2 to 4 As shown, each measuring tube module 20, 40, 60 of the modular measuring device 1 has a limiter 21, 41, 61 complementary to the housing 11 of the support module 10, a vibrating tube 22, 42, 62, an auxiliary exciter component 23, 43, 63 complementary to the main exciter component 13, and an auxiliary sensor component 24, 44, 64 complementary to the main sensor component 14.

[0029] The limiters 21, 41, and 61 are, for example, plate-like elements whose thickness corresponds to the width of the groove, allowing the limiters 21, 41, and 61 to be inserted into the groove. Preferably, the limiters 21, 41, and 61 and / or the receiver 11 have stops to arrange the measuring tube modules 20, 40, and 60 in a predetermined and reproducible position within the support module 10. Of course, other embodiments of the limiters are also possible, as long as these embodiments can hold the measuring tube modules 20, 40, and 60 in a form-locking manner and precisely within the support module 10 of the modular measuring device 1.

[0030] Preferably, the auxiliary exciter components 23, 43, and 63 of the measuring tube modules 20, 40, and 60 are arranged on the measuring tube modules 20, 40, and 60 along the longitudinal axis Y, wherein the vibrating tubes 22, 42, and 62 are symmetrical about the longitudinal axis Y. The main exciter component 13 includes a coil, and the auxiliary exciter components 23, 43, and 63 include permanent magnets, or the auxiliary exciter components 23, 43, and 63 include coils, and the main exciter component 13 includes permanent magnets. The auxiliary exciter components 23, 43, and 63 are preferably arranged inside the tube legs 25, 26, 45, 46, 65, and 66, i.e., on the side facing the longitudinal axis Y. The auxiliary exciter components 23, 43, and 63 are thus particularly well protected from damage.

[0031] Preferably, the auxiliary sensor components 24, 44, 64 are arranged on the first legs 25, 45, 65 of the measuring tube modules 20, 40, 60, or on the second legs 26, 46, 66 of the measuring tube modules 20, 40, 60. The main sensor component 14 includes a coil, and the auxiliary sensor components 24, 44, 64 include permanent magnets, or the auxiliary sensor components 24, 44, 64 include coils, and the main sensor component 14 includes permanent magnets. Preferably, the auxiliary sensor components 24, 44, 64 are arranged inside the legs 25, 26, 45, 46, 65, 66, i.e., on the side facing the longitudinal axis Y. The auxiliary sensor components 24, 44, 64 are thus particularly well protected from damage.

[0032] like Figures 2 to 4As shown, each vibrating tube 22, 42, 62 of the measuring tube modules 20, 40, 60 has different tube diameters RD1, RD2, RD3, straight first tube legs 25, 45, 65, straight second tube legs 26, 46, 66, bent first tube elbows 27, 47, 67, and bent second tube elbows 28, 48, 68. Preferably, the vibrating tubes 22, 42, 62 have a circular cross-sectional shape. Of course, the vibrating tubes can have any other cross-sectional shape, as long as it is compatible with the technical teachings of the present invention. The vibrating tubes 22, 42, 62 are preferably made of corrosion-resistant metal (e.g., stainless steel) or plastic. The tube diameters RD1, RD2, RD3 of the vibrating tubes 22, 42, 62 of the measuring tube modules 20, 40, 60 are preferably between 3 mm and 15 mm. The tube diameter is measured at the outer surface of the vibrating tube.

[0033] Figure 5 A side view of the stacked measuring tube modules 20, 40, and 60 is shown. In this illustration, the difference D1 between the diameter RD1 of the vibrating tube 22 of the first measuring tube module 20 and the diameter RD2 of the vibrating tube 42 of the second measuring tube module 40 is clearly visible. The difference D2 between the diameter RD1 of the vibrating tube 22 of the first measuring tube module 20 and the diameter RD3 of the vibrating tube 62 of the third measuring tube module 60, and the difference D3 between the diameter RD2 of the vibrating tube 42 of the second measuring tube module 40 and the diameter RD3 of the vibrating tube 62 of the third measuring tube module 60 are also shown.

[0034] To better understand, Figure 5 The cross-sectional projections of the vibrating tubes 22, 42, and 62 at different locations are also shown (as indicated by dashed lines). These stacked views are obtained when the measuring tube modules 20, 40, and 60 are each arranged within the support module 10. The precise positioning of the measuring tube modules 20, 40, and 60 within the support module 10 is reproducible due to the housing 11 of the support module 10 and the limiters 21, 41, and 61 of the measuring tube modules 20, 40, and 60. Figure 5 Plane E1 assigned to the first measuring tube module 20, plane E2 assigned to the second measuring tube module 40, and plane E3 assigned to the third measuring tube module 60 are also shown. Planes E1, E2, and E3 define the connection points, or connection planes, between the straight tube legs 25, 26, 45, 46, 65, 66 and the curved tube elbows 27, 28, 47, 48, 67, 68. These connection points will be discussed in detail later. In this document, the connection point is understood as the joint between the straight tube leg and the curved tube elbow. Therefore, in the case of a cylindrical vibrating tube, the joint has a circular shape.

[0035] exist Figure 6To aid understanding, different line types are used for each different measuring tube module. Dashed lines indicate information related to the first measuring tube module 20. Dashed lines indicate information related to the second measuring tube module 40. Dotted lines indicate information related to the third measuring tube module 60.

[0036] Figure 6 It is shown that the first tube legs 25, 45, and 65 are each connected to the first tube elbows 27, 47, and 67 at main connection points VP1, VP2, and VP3, respectively. The first tube elbows 27, 47, and 67 are connected to the second tube elbows 28, 48, and 68. The second tube elbows 28, 48, and 68 are each connected to the first tube legs 25, 45, and 65 at auxiliary connection points VS1, VS2, and VS3, respectively. In other words, each measuring tube module 20, 40, and 60 can be assigned main connection points and auxiliary connection points, as shown below. Figure 6 As shown. For each measuring tube module 20, 40, 60, the main connection points VP1, VP2, VP3 and the auxiliary connection points VS1, VS2, VS3 are located in the corresponding planes E1, E2, E3 assigned to the measuring tube module. Planes E1, E2, E3 are arranged parallel to each other at predetermined distances. The plane E1 of the first measuring tube module 20 is separated from the plane E2 of the second measuring tube module 40 by a distance A1. The plane E1 of the first measuring tube module 20 is separated from the plane E3 of the third measuring tube module 60 by a distance A2. The plane E2 of the second measuring tube module 40 is separated from the plane E3 of the third measuring tube module 60 by a distance A3.

[0037] Distance A1 corresponds to the difference D1 between the diameter RD1 of the vibrating tube 22 of the first measuring tube module 20 and the diameter RD2 of the vibrating tube 42 of the second measuring tube module 40. Distance A2 corresponds to the difference D2 between the diameter RD1 of the vibrating tube 22 of the first measuring tube module 20 and the diameter RD3 of the vibrating tube 62 of the third measuring tube module 60. Distance A3 corresponds to the difference D3 between the diameter RD2 of the vibrating tube 42 of the second measuring tube module 40 and the diameter RD3 of the vibrating tube 62 of the third measuring tube module 60.

[0038] like Figure 6 As shown by the various offset circular lines, preferably, the first pipe elbows 27, 47, 67 and the second pipe elbows 28, 48, 68 have the same inner radii IR1, IR2, IR3. Alternatively, the different pipe elbows may also have the same outer radii AR1, AR2, AR3 (in... Figure 6(This refers only to the first measuring tube module). Due to the spacing of planes E1, E2, E3 and the same inner radii IR1, IR2, IR3 and correspondingly the same outer radii AR1, AR2, AR3, the center lines ML1, ML2, ML3 associated with vibrating tubes 22, 42, 62 intersect at the first intersection point S1 and the second intersection point S2. The corresponding center lines of the vibrating tubes pass through the center of the vibrating tube.

[0039] Therefore, the first vibrating tube has a centerline ML1. Therefore, the second vibrating tube has a centerline ML2. Therefore, the third vibrating tube has a centerline ML3. Therefore, in the straight legs of the vibrating tube, the centerline corresponds to the cylindrical axis of the leg. The first intersection point S1 or the second intersection point S2 can also be understood as an intersecting region or intersecting volume. This means that all the centerlines of the different measuring tube modules intersect in the intersecting region or intersecting volume. This intersecting region is preferably a few square millimeters, for example, 1 mm. 2 Up to 25mm 2 The intersection volume is preferably a few cubic millimeters, for example, 1 mm. 3 Up to 125mm 3 .

[0040] A non-contact temperature sensor 12 is arranged in the support module 10 such that when the measuring tube modules 20, 40, and 60 are received in the support module 10, the non-contact temperature sensor 12 points towards either the first intersection point S1 or the second intersection point S2. This achieves the alignment axis of the temperature sensor 12 intersecting the first intersection point S1 or the second intersection point S2, and the measurement signal of the temperature sensor 12 extends along this alignment axis. This allows the measurement signal (e.g., the optical infrared signal from the temperature sensor 12 for each measuring tube module 20, 40, and 60) to be incident on the surfaces of the vibrating tubes 22, 42, and 62 that are orthogonal to the alignment axis of the temperature sensor 12. Therefore, due to the orthogonal arrangement of the surfaces of the vibrating tubes 22, 42, and 62, the measurement signal is optimally mirror-reflected back to the temperature sensor 12 along the alignment axis, thereby achieving accurate temperature measurement.

[0041] According to embodiments of measuring tube modules 20, 40, and 60 (not shown), tube segments are arranged between first tube bends 27, 47, and 67 and second tube bends 28, 48, and 68. For example, the tube segments may be straight or curved. Such tube segments, for example, provide sufficient space for auxiliary actuator bodies 23, 43, and 63.

[0042] like Figure 5As shown, preferably, the first legs 25, 45, 65 and the second legs 26, 46, 66 extend parallel to each other. Of course, the first legs 25, 45, 65 and the second legs 26, 46, 66 can also be arranged non-parallel to each other, as long as the two legs are arranged symmetrically about the longitudinal axis Y of the measuring tube modules 20, 40, 60.

[0043] according to Figure 1 In the illustrated embodiment, each measuring tube module 20, 40, 60 has at least two identical vibrating tubes 22, 42, 62. However, each measuring tube module 20, 40, 60 may also have more than two identical vibrating tubes, provided it is technically feasible.

[0044] like Figure 5 As shown, in each case, the measuring tube modules 20, 40, and 60 extend along the longitudinal axis Y, and the corresponding vibrating tubes 22, 42, and 62 are symmetrical about this longitudinal axis Y. All measuring tube modules 20, 40, and 60 preferably have the same extension length along the longitudinal axis Y.

[0045] Figure 6 The diagram shows measuring tube modules 20, 40, and 60 extending along the longitudinal axis Y, with vibrating tubes 22, 42, and 62 symmetrical about this longitudinal axis Y. Preferably, all vibrating tubes 22, 42, and 62 intersect at a third intersection point S3, which is located on the longitudinal axis Y when each of the vibrating tubes 22, 42, and 62 is arranged in the support module 10. In other words, when arranged in the support module 10, each vibrating tube 22, 42, and 62 extends to the intersection point S3. The intersection point S3 thus also forms the apex of the vibrating tubes 22, 42, and 62.

[0046] If the bends 27, 28, 47, 48, 67, and 68 of the vibrating pipes 22, 42, and 62 have the same inner radii IR1, IR2, and IR3, then the intersection point S3 will be located on the outside of the vibrating pipe, as shown below. Figure 6 As shown.

[0047] If the inner radii IR1, IR2, and IR3 of the pipe bends are the same, when the measuring pipe modules 20, 40, and 60 are arranged such that one measuring pipe module is on top of another, the inner sides of all first pipe legs 25, 45, and 65, and the inner sides of all second pipe legs 26, 46, and 66, will be flush with each other (see [reference]). Figure 5 It goes without saying that the term "inner side" here refers to this bend in the measuring tube module, that is, the bend facing the inner radius.

[0048] If the bends 27, 28, 47, 48, 67, and 68 of the vibrating tubes 22, 42, and 62 have the same outer radii AR1, AR2, and AR3, then the intersection point S3 will be located inside the vibrating tube (not shown). It goes without saying that here, the term "inside" refers to this bend of the measuring tube module, i.e., the bend facing the inner radius.

[0049] If the outer radii AR1, AR2, and AR3 of the pipe bends are the same, when the measuring pipe modules 20, 40, and 60 are arranged such that one measuring pipe module is on top of another, the outer sides of all the first pipe legs 25, 45, and 65, and the outer sides of all the second pipe legs 26, 46, and 66, will be flush with each other (not shown). It goes without saying that the term "outer side" here refers to this bend of the measuring pipe module, i.e., the bend facing away from the inner radius.
