Description

Technical Field

[0001] This utility model belongs to the field of fluid detection technology, specifically relating to a fluid measurement pipeline structure, a fluid measurement device, and a fluid measurement system. Background Technology

[0002] With the development of technology, the application of ultrasonic time-of-flight measurement technology for fluid velocity and flow rate measurement is becoming increasingly widespread.

[0003] Taking a small-diameter ultrasonic water meter as an example, to measure water flow velocity and flow rate, a pair of ultrasonic transducers are typically placed at opposite ends of the measuring pipe near the meter. One transducer acts as the ultrasonic excitation transmitter, while the other acts as the receiving transducer, and vice versa. When the ultrasonic signal propagates in the direction of water flow, its speed increases and its propagation time shortens; when it propagates against the direction of water flow, its speed decreases and its propagation time increases. By accurately measuring the time difference (i.e., time difference) between the propagation of the ultrasonic signal in the forward and reverse directions, the water flow velocity can be calculated. Furthermore, by considering the geometry of the measuring pipe and parameters such as water temperature and pressure, the flow rate of the water currently flowing through the measuring pipe can be calculated.

[0004] Due to space limitations, transducers in small-diameter ultrasonic water meters are typically placed in parallel. The transmission and reception of ultrasonic waves are achieved by setting up two reflective panels. These reflective panels usually utilize a reduced-diameter pipe section and are installed inside the main measuring pipeline. The complex structure of the reduced-diameter pipe section increases the complexity and assembly difficulty of the entire measuring device, as well as the manufacturing difficulty and cost. The complex structure of the reduced-diameter pipe section also obstructs water flow, resulting in water pressure loss and increasing the complexity of the water flow field, thereby reducing the stability of measurement accuracy. Furthermore, since the reflective panels are placed in the middle of the measuring pipeline through the reduced-diameter pipe section, the measuring pipeline is easily blocked by foreign objects, which is not conducive to the widespread application of ultrasonic water meters.

[0036] Secondly, this utility model embodiment also provides a fluid measuring device, which includes a first transducer, a second transducer, a control board, and the fluid measuring pipeline structure described in any embodiment of the first aspect;

[0037] The first transducer is installed in the first mounting slot, and the second transducer is installed in the second mounting slot. The first transducer and the second transducer are electrically connected to the control board respectively.

[0038] Thirdly, embodiments of this application also provide a fluid measurement system, the fluid measurement system comprising a main pipeline and the fluid measurement device described in the second aspect;

[0039] The main pipeline and the first section of the fluid measuring device are connected.

[0040] As can be seen from the above embodiments, in this application embodiment, since the third pipe segment is located between the first pipe segment and the second pipe segment, and the third pipe segment connects the first pipe segment and the second pipe segment, the first pipe segment and the second pipe segment extend along the first direction, the third pipe segment extends along the second direction, the first direction and the second direction intersect, the end of the first pipe segment away from the first reflective panel has a first mounting groove, and the end of the second pipe segment away from the second reflective panel has a second mounting groove. Both the first mounting groove and the second mounting groove are used to install transducers. Therefore, a fluid flow channel can be formed through the first pipe segment, the second pipe segment and the third pipe segment, and an ultrasonic wave propagation channel can be formed simultaneously through the first pipe segment, the second pipe segment and the third pipe segment, thereby reducing the manufacturing difficulty and manufacturing cost of the volume measurement pipe structure.

[0041] Furthermore, since the first reflective panel is located between the first and third pipe sections, and the second reflective panel is located between the second and third pipe sections, the first, second, and third pipe sections, the first reflective panel, and the second reflective panel constitute an integral structure. The angle between the axis of the first pipe section and the normal of the first reflective panel is equal to the angle between the axis of the third pipe section and the normal of the first reflective panel, and the angle between the axis of the second pipe section and the normal of the second reflective panel is equal to the angle between the axis of the third pipe section and the normal of the second reflective panel. Therefore, the first and second reflective panels required for ultrasonic wave propagation are directly formed from a portion of the fluid flow channel, thereby reducing the structural complexity of the entire fluid measurement pipeline structure. Simultaneously, by making the first and second reflective surfaces part of the inner wall of the fluid flow channel, on the one hand, it reduces obstruction to the fluid, reduces fluid pressure loss, and reduces the complexity of the fluid flow field, thus improving measurement stability; on the other hand, it also prevents foreign objects from blocking the fluid flow channel, facilitating the widespread application of the fluid measurement pipeline structure.

[0063] Please refer to Figures 1 to 6 This application provides a fluid measurement pipeline structure, which includes:

[0064] First pipe section 11, second pipe section 12, third pipe section 13, first reflective panel 14 and second reflective panel 15.

[0065] The third pipe segment 13 is located between the first pipe segment 11 and the second pipe segment 12, and the third pipe segment 13 connects the first pipe segment 11 and the second pipe segment 12. The first pipe segment 11 and the second pipe segment 12 extend along the first direction, and the third pipe segment 13 extends along the second direction. The first direction and the second direction intersect.

[0066] The first reflective panel 14 is located between the first pipe section 11 and the third pipe section 13, and the second reflective panel 15 is located between the second pipe section 12 and the third pipe section 13. The first pipe section 11, the second pipe section 12, the third pipe section 13, the first reflective panel 14, and the second reflective panel 15 constitute an integral structure.

[0067] The angle between the axis of the first pipe segment 11 and the normal of the first reflective panel 14 is equal to the angle between the axis of the third pipe segment 13 and the normal of the first reflective panel 14, and the angle between the axis of the second pipe segment 12 and the normal of the second reflective panel 15 is equal to the angle between the axis of the third pipe segment 13 and the normal of the second reflective panel 15.

[0068] The first pipe segment 11 has a first mounting groove 111 at the end away from the first reflective panel 14, and the second pipe segment 12 has a second mounting groove 121 at the end away from the second reflective panel 15. Both the first mounting groove 111 and the second mounting groove 121 are used to install transducers.

[0069] As can be seen from the above embodiments, in this application embodiment, since the third pipe segment 13 is located between the first pipe segment 11 and the second pipe segment 12, and the third pipe segment 13 connects the first pipe segment 11 and the second pipe segment 12, the first pipe segment 11 and the second pipe segment 12 extend along the first direction, and the third pipe segment 13 extends along the second direction, the first direction and the second direction intersect, the end of the first pipe segment 11 away from the first reflective panel 14 has a first mounting groove 111, and the end of the second pipe segment 12 away from the second reflective panel 15 has a second mounting groove 121. The first mounting groove 111 and the second mounting groove 121 are both used to install transducers. Therefore, a fluid flow channel can be formed through the first pipe segment 11, the second pipe segment 12 and the third pipe segment 13, and an ultrasonic wave propagation channel can be formed simultaneously through the first pipe segment 11, the second pipe segment 12 and the third pipe segment 13. Compared with the measuring pipe of the traditional measuring device, the structure of the measuring pipe of the measuring device of this utility model is greatly simplified, thereby reducing the manufacturing difficulty and manufacturing cost of the volume measuring pipe structure.

[0070] Furthermore, since the first reflective panel 14 is located between the first pipe segment 11 and the third pipe segment 13, and the second reflective panel 15 is located between the second pipe segment 12 and the third pipe segment 13, the first pipe segment 11, the second pipe segment 12, the third pipe segment 13, the first reflective panel 14, and the second reflective panel 15 constitute an integral structure. The angle between the axis of the first pipe segment 11 and the normal of the first reflective panel 14 is equal to the angle between the axis of the third pipe segment 13 and the normal of the first reflective panel 14. The angle between the axis of the second pipe segment 12 and the normal of the second reflective panel 15 is equal to the angle between the axis of the third pipe segment 13 and the normal of the second reflective panel 15. Therefore, the first reflective panel 14 and the second reflective panel 15 required for ultrasonic wave propagation are directly formed from a part of the fluid flow channel, thereby reducing the complexity of the entire fluid measurement pipeline structure. Meanwhile, the first reflective panel 14 and the second reflective panel 15 are directly formed from a part of the fluid flow channel. On the one hand, this can reduce the obstruction to the fluid, reduce the pressure loss of the fluid, reduce the complexity of the fluid flow field, and thus improve the stability of the measurement. On the other hand, it can also prevent foreign objects from blocking the fluid flow channel, which facilitates the promotion and application of fluid measurement pipeline structures.

[0071] In the above embodiments, the first pipe segment 11, the second pipe segment 12, the third pipe segment 13, the first reflective panel 14, and the second reflective panel 15 can be integrally formed or integrally formed by welding multiple tubular structures. This application does not limit this aspect. The first pipe segment 11, the first reflective panel 14, the second pipe segment 12, the second reflective panel 15, and the third pipe segment 13 form a U-shaped structure. The first pipe segment 11 can serve as a fluid inlet channel and also as a channel for the transducer to receive and transmit ultrasonic waves. The second pipe segment 12 can serve as a fluid outlet channel and also as a channel for another transducer to receive and transmit ultrasonic waves. The third pipe segment 13 can form a closed fluid passage and fluid measurement pipe segment, mainly used for fluid flow and ultrasonic wave propagation.

[0072] It should be noted that the placement positions of the first reflective panel 14 and the second reflective panel 15 need to be determined based on the path of ultrasonic wave transmission, reflection, and reception. Specifically, the angle between the axis of the first pipe segment 11 and the normal of the first reflective panel 14 is equal to the angle between the axis of the third pipe segment 13 and the normal of the first reflective panel 14, and the angle between the axis of the second pipe segment 12 and the normal of the second reflective panel 15 is equal to the angle between the axis of the third pipe segment 13 and the normal of the second reflective panel 15. Therefore, it can be ensured that the signal emitted by the transducer installed in the first mounting groove 111 at the end of the first pipe segment 11 away from the first reflective panel 14 can be reflected by the first reflective panel 14, enter the third pipe segment, and be reflected by the second reflective panel 15 to the transducer in the second mounting groove 121 at the end of the second pipe segment 12 away from the second reflective panel 15 for reception. Meanwhile, the signal emitted by the transducer in the second mounting groove 121 at the end of the second pipe section 12 away from the second reflective panel 15 can be reflected by the second reflective surface, enter the third pipe section, and be reflected by the first reflective panel 14 to the transducer installed in the first mounting groove 111 at the end of the first pipe section 11 away from the first reflective panel 14 for reception.

[0073] Specifically, such as Figure 12As shown, when the fluid measurement pipe structure in the above embodiment is applied to a fluid measurement device for measuring water flow rate, the transducer installed in the first mounting groove 111 at the end of the first pipe section 11 away from the first reflective panel 14 can serve as an excitation transmitting transducer, and the transducer in the second mounting groove 121 at the end of the second pipe section 12 away from the second reflective panel 15 can serve as a receiving responding transducer. Conversely, the transducer installed in the second mounting groove 121 at the end of the second pipe section 12 away from the second reflective panel 15 can serve as an excitation transmitting transducer, and the transducer in the first mounting groove 111 at the end of the first pipe section 11 away from the first reflective panel 14 can serve as a receiving responding transducer. When the ultrasonic signal propagates in the direction of water flow, the speed increases and the propagation time shortens; when it propagates against the direction of water flow, the speed decreases and the propagation time lengthens. By accurately measuring the time difference (i.e., time difference) of ultrasonic signal propagation in the upstream and downstream directions, the water flow velocity can be calculated. Then, by considering the geometry of the fluid measurement pipe and parameters such as water temperature and pressure, the current water flow rate through the pipe can be calculated. The flow direction of the fluid within the fluid measurement pipe structure is as follows: Figure 12 As shown by arrow W in the diagram, the direction in which the ultrasonic wave propagates along the water flow direction in the fluid measurement pipe structure is as follows: Figure 12 As shown by arrow M, the direction of ultrasonic wave propagation against the water flow direction in the fluid measurement pipe structure is as follows: Figure 12 As indicated by arrow N in the diagram.

[0074] It should be noted that, to reduce the complexity of the entire fluid measurement pipeline structure, the embodiments of this application make the first and second reflective surfaces directly formed from a portion of the fluid flow channel. Specifically, the example is an integral structure formed by welding multiple tubular sections 11, 12, 13, 14, and 15. First, the pipe section profiles are cut and prepared. Then, the positions of the pre-set first reflective panel 14 and second reflective panel 15 on the pipe section are polished to form a mirror surface, reducing diffuse reflection and ensuring that ultrasonic waves can be effectively reflected during use. Next, the pipe section profiles are bent and assembled to form a closed hollow pipe section. Then, the pipe section profiles are welded and fixed, and the joints of the bent and assembled pipe section profiles are welded to form the first pipe section 11, the second pipe section 12, and the third pipe section 13. The welded pipe sections are then subjected to non-destructive testing, such as ultrasonic testing, to check for weld defects and prevent fluid leakage during future use.

[0075] Furthermore, in this embodiment, the first pipe segment 11 and the second pipe segment 12 extend along a first direction, and the third pipe segment 13 extends along a second direction. The first and second directions intersect, allowing the first direction to be longitudinal or tending towards longitudinal, and the second direction to be transverse or tending towards transverse. Thus, when fluid passes through the first pipe segment 11 and enters the third pipe segment 13, a co-current flow can be formed if the fluid flows along the first pipe segment 11 to the third pipe segment 13 and then to the second pipe segment 12; conversely, a counter-current flow can be formed if the fluid flows in the opposite direction, thereby satisfying the requirements for fluid measurement.

[0076] In some embodiments, the fluid measurement pipeline structure further includes at least one of a fourth pipe segment 16 and a fifth pipe segment 17, wherein the fourth pipe segment 16 is connected to the first pipe segment 11 and is disposed on the side of the first pipe segment 11 away from the second pipe segment 12, and the axis of the first pipe segment 11 intersects the axis of the fourth pipe segment 16; and the fifth pipe segment 17 is connected to the second pipe segment 12 and is disposed on the side of the second pipe segment 12 away from the first pipe segment 11, and the axis of the second pipe segment 12 intersects the axis of the fifth pipe segment 17.

[0077] In this embodiment, the fluid measurement pipeline structure may include a fourth pipe segment 16, a fifth pipe segment 17, or both. This application does not limit the specific inclusion of either. Since the fourth pipe segment 16 connects to the first pipe segment 11 and is located on the side of the first pipe segment 11 away from the second pipe segment 12, and the axis of the first pipe segment 11 intersects with the axis of the fourth pipe segment 16, and the fifth pipe segment 17 connects to the second pipe segment 12 and is located on the side of the second pipe segment 12 away from the first pipe segment 11, and the axis of the second pipe segment 12 intersects with the axis of the fifth pipe segment 17, the overall length of the fluid measurement pipeline structure can be extended using the fourth pipe segment 16 and the fifth pipe segment 17. This extends the flow path of the fluid within the fluid measurement pipeline structure, increasing the stability of the overall fluid flow. Specifically, the fourth pipe segment 16 increases the length of the upstream straight pipe section of the fluid measurement pipeline structure, thereby enabling the fluid to form a stable velocity profile and reducing eddy currents or turbulence interference caused by bends in the fluid measurement pipeline structure, thus improving measurement accuracy. If the straight pipe section is insufficient, fluid disturbance will cause unstable ultrasonic signal propagation, increasing measurement error. A stable flow field can avoid asymmetric velocity distribution along the ultrasonic propagation path, ensuring the accuracy of flow rate calculation using the time difference method. Furthermore, the inclusion of the fifth pipe section 17 can reduce the impact of input errors in the flow area of ​​the fluid measurement pipe structure on the measurement results, thereby reducing the uncertainty caused by local deformation or installation deviations in the fluid measurement pipe structure, and also minimizing the impact of accumulated errors at the connection points.

[0078] In some embodiments, the flow area of ​​the third pipe segment 13 is less than or equal to any one of the flow areas of the first pipe segment 11, the second pipe segment 12, the fourth pipe segment 16, and the fifth pipe segment 17.

[0079] In this embodiment, since the flow area of ​​the third pipe section 13 is less than or equal to any one of the flow areas of the first pipe section 11, the second pipe section 12, the fourth pipe section 16, and the fifth pipe section 17, it can be ensured that the flow area of ​​the third pipe section 13 is the smallest among all pipe sections in the entire fluid measurement pipeline structure. This increases the flow velocity of the fluid passing through the third pipe section 13, thereby increasing the time difference between the downstream and upstream propagation of ultrasonic waves, and thus improving the measurement accuracy of fluid velocity and flow rate. Simultaneously, with the flow area of ​​the third pipe section 13 being the smallest among all pipe sections in the entire fluid measurement pipeline structure, the volume of the fluid measurement pipeline structure can be reduced while maintaining measurement accuracy. This facilitates the application of the fluid measurement pipeline structure in confined space installation environments, improving the adaptability of the fluid measurement pipeline structure.

[0080] In some embodiments, the flow area of ​​the first pipe section 11, the flow area of ​​the second pipe section 12, and the flow area of ​​the third pipe section 13 are all equal.

[0081] In this embodiment, since the flow areas of the first pipe section 11, the second pipe section 12, and the third pipe section 13 are all equal, and given that the flow area of ​​the third pipe section 13 is the smallest in the entire fluid measurement pipeline structure, the flow areas of the first pipe section 11, the second pipe section 12, and the third pipe section 13 can all be minimized. This reduces eddy current or turbulence interference at points where the flow area changes, and also increases the overall flow velocity of the fluid in the first pipe section 11, the third pipe section 13, and the second pipe section 12, thereby increasing the time difference between ultrasonic wave propagation in the forward and reverse directions, and thus improving the measurement accuracy of fluid velocity and flow rate. Similarly, with the flow areas of the first pipe section 11, the second pipe section 12, and the third pipe section 13 all minimized, the volume of the fluid measurement pipeline structure can be further reduced, lowering costs while improving the adaptability of the fluid measurement pipeline structure.

[0082] In some embodiments, the fluid measurement pipeline structure further includes a first seal 18 and a second seal 19. The first seal 18 is disposed at the bottom of the first mounting groove 111 to seal the gap between the transducer and the first mounting groove 111. The second seal 19 is disposed at the bottom of the second mounting groove 121 to seal the gap between the transducer and the second mounting groove 121.

[0083] In this embodiment, the first sealing element 18 and the second sealing element 19 can be made of interwoven materials such as nitrile rubber, EPDM rubber, silicone rubber, and fluororubber. The first sealing element 18 and the second sealing element 19 can also be made of plastics and polymers such as polytetrafluoroethylene and polyurethane; this embodiment does not limit the specific materials used. Thus, since the first sealing element 18 is located at the bottom of the first mounting groove 111 and the second sealing element 19 is located at the bottom of the second mounting groove 121, the first sealing element 18 can seal the gap between the transducer and the first mounting groove 111, and the second sealing element 19 can seal the gap between the transducer and the second mounting groove 121. This prevents fluid from entering the fluid measurement pipeline structure through the gap between the transducer and the first mounting groove 111 or the gap between the transducer and the second mounting groove 121. Simultaneously, it prevents fluid inside the fluid measurement pipeline structure from flowing out through the gap between the transducer and the first mounting groove 111 or the gap between the transducer and the second mounting groove 121, ensuring the airtightness of the entire fluid measurement pipeline structure and the transducer after installation.

[0084] In some embodiments, the flow area of ​​the fourth pipe section 16 and the flow area of ​​the fifth pipe section 17 are both smaller than the first flow area, which is the flow area of ​​the main pipe assembled with the fluid measurement pipe structure.

[0085] In this embodiment, the flow area of ​​the fourth pipe section 16 and the flow area of ​​the fifth pipe section 17 are both smaller than the first flow area. The first flow area is the flow area of ​​the main pipe assembled with the fluid measurement pipe structure. Therefore, it can ensure that the flow velocity of the main pipe increases when it enters the fourth pipe section, thereby increasing the time difference between the ultrasonic wave propagation in the forward and reverse directions, thus improving the measurement accuracy of fluid velocity and flow rate, while ensuring the stability of the flow velocity and flow rate when the fluid flows out of the fifth pipe section 17.

[0086] In some embodiments, the flow area of ​​the first pipe section 11, the flow area of ​​the second pipe section 12, the flow area of ​​the third pipe section 13, the flow area of ​​the fourth pipe section 16, and the flow area of ​​the fifth pipe section 17 are all smaller than the first flow area, which is the flow area of ​​the main pipe assembled with the fluid measurement pipe structure.

[0087] In this embodiment, since the flow area of ​​the first pipe section 11, the flow area of ​​the second pipe section 12, the flow area of ​​the third pipe section 13, the flow area of ​​the fourth pipe section 16, and the flow area of ​​the fifth pipe section 17 are all smaller than the first flow area, it can ensure that the flow velocity of the entire fluid in the measuring pipe structure is maximized, thereby increasing the time difference between the ultrasonic wave propagation in the forward and reverse directions, and thus improving the measurement accuracy of fluid velocity and flow rate.

[0088] In some embodiments, the fluid measurement pipeline structure further includes a first transfer pipe section 101 and a second transfer pipe section 102, wherein the first transfer pipe section 101 and the end of the fourth pipe section 16 away from the first pipe section 11 are connected, and the second transfer pipe section 102 and the end of the fifth pipe section 17 away from the second pipe section 12 are connected.

[0089] In this embodiment, the ends of the first transfer pipe section 101 and the fourth pipe section 16 furthest from the first pipe section 11 are connected, and the ends of the second transfer pipe section 102 and the fifth pipe section 17 furthest from the second pipe section 12 are connected. Therefore, the first transfer pipe section 101 can be connected to the main pipeline, and the second transfer pipe section 102 can be connected to the fluid outlet, thereby facilitating the installation, deployment, and application of the entire fluid measurement pipeline structure. It should be noted that the first transfer pipe section 101 and the fourth pipe section 16 can be connected by flange connection, welding, threaded connection, etc., and the second transfer pipe section 102 and the fifth pipe section 17 can be connected by flange connection, welding, threaded connection, etc. This embodiment does not limit the connection in this way.

[0090] In some embodiments, the fluid measurement pipeline structure further includes a first adapter panel 103 and a second adapter panel 104. The first adapter pipe section 101 is connected to the end of the fourth pipe section 16 away from the first pipe section 11 through the first adapter panel 103, and the second adapter pipe section 102 is connected to the end of the fifth pipe section 17 away from the second pipe section 12 through the second adapter panel 104.

[0091] In this embodiment, since the first transfer pipe section 101 is connected to the end of the fourth pipe section 16 away from the first pipe section 11 through the first transfer panel 103, and the second transfer pipe section 102 is connected to the end of the fifth pipe section 17 away from the second pipe section 12 through the second transfer panel 104, the connection between the first transfer pipe section 101 and the fourth pipe section 16 with different flow areas can be realized through the first transfer panel 103, and the connection between the second transfer pipe section 102 and the fifth pipe section 17 with different flow areas can be realized through the second transfer panel 104, thereby ensuring the stability of the fluid flow in the fluid measurement pipe structure.

[0092] In some embodiments, the cross-sections of the first pipe segment 11, the second pipe segment 12, the third pipe segment 13, the fourth pipe segment 16, and the fifth pipe segment 17 are all rectangular.

[0093] In this embodiment, since the cross-sections of the first pipe section 11, the second pipe section 12, the third pipe section 13, the fourth pipe section 16, and the fifth pipe section 17 are all rectangular, it can ensure that the flow shape of each pipe section in the fluid measurement pipeline structure is the same, thereby avoiding eddy currents or turbulence interference generated when the fluid flows in pipe sections with different flow shapes. On the other hand, it makes the shape of each pipe section in the fluid measurement pipeline structure the same, which facilitates parameter control. While reducing manufacturing errors, it can also reduce the processing and manufacturing cost of the fluid measurement pipeline structure.

[0094] In some embodiments, the cross-sections of the first pipe segment 11, the second pipe segment 12, the third pipe segment 13, the fourth pipe segment 16, and the fifth pipe segment 17 are all circular.

[0095] In this embodiment, since the cross-sections of the first pipe segment 11, the second pipe segment 12, the third pipe segment 13, the fourth pipe segment 16, and the fifth pipe segment 17 are all circular, it can ensure that the flow shape of each pipe segment in the fluid measurement pipeline structure is the same, thereby avoiding eddy currents or turbulence interference generated when the fluid flows through pipe segments with different flow shapes. On the other hand, it makes the shape of each pipe segment in the fluid measurement pipeline structure the same, which facilitates parameter control. While reducing manufacturing errors, it can also reduce the processing and manufacturing cost of the fluid measurement pipeline structure.

[0096] In some embodiments, such as Figure 13 As shown, the axis of the first pipe segment 11 intersects the axis of the second pipe segment 12.

[0097] In this embodiment, since the axis of the first pipe segment 11 intersects the axis of the second pipe segment 12, the fluid in the first pipe segment 11 and the second pipe segment 12 flows obliquely. Similarly, a fluid flow channel can be formed through the first pipe segment 11, the second pipe segment 12 and the third pipe segment 13, and an ultrasonic wave propagation channel can also be formed through the first pipe segment 11, the second pipe segment 12 and the third pipe segment 13.

[0098] In some embodiments, the angle between the axis of the first pipe segment 11 and the axis of the third pipe segment 13, and the angle between the axis of the second pipe segment 12 and the axis of the third pipe segment 13 are both obtuse angles.

[0099] In this embodiment, since the angles between the axes of the first pipe segment 11 and the third pipe segment 13, and the angles between the axes of the second pipe segment 12 and the third pipe segment 13 are both obtuse angles, even when the axes of the first pipe segment 11 and the second pipe segment 12 intersect, it can be ensured that the angle between the axis of the first pipe segment 11 and the normal of the first reflective panel 14 is equal to the angle between the axis of the third pipe segment 13 and the normal of the first reflective panel 14, and the angle between the axis of the second pipe segment 12 and the normal of the second reflective panel 15 is equal to the angle between the axis of the third pipe segment 13 and the normal of the second reflective panel 15, thus ensuring that ultrasonic waves can propagate between the two transducers.

[0100] In some embodiments, such as Figure 3 As shown, the axis of the first pipe section 11 is parallel to the axis of the second pipe section 12.

[0101] In this embodiment, since the axis of the first pipe segment 11 and the axis of the second pipe segment 12 are parallel, the flow direction of the fluid in the first pipe segment 11 and the flow direction of the fluid in the second pipe segment 12 can be completely opposite. This facilitates the formation of fluid flow channels and ultrasonic wave propagation channels through the first pipe segment 11, the second pipe segment 12 and the third pipe segment 13, while also making the formation between the first pipe segment 11, the second pipe segment 12 and the third pipe segment 13 easier.

[0102] In some embodiments, the angle between the axis of the first pipe segment 11 and the axis of the third pipe segment 13, and the angle between the axis of the second pipe segment 12 and the axis of the third pipe segment 13 are both right angles.

[0103] In this embodiment, since the angles between the axis of the first pipe section 11 and the axis of the third pipe section 13, and the angles between the axis of the second pipe section 12 and the axis of the third pipe section 13 are both right angles, the fluid can have a sufficient drop when entering the third pipe section 13 from the first pipe section 11, ensuring the flow velocity of the fluid in the third pipe section 13 and improving the accuracy of fluid measurement pipeline structure detection. At the same time, after flowing out through the third pipe section 13, the flow velocity of the fluid can be slowed down, which facilitates the control of the fluid outflow.

[0104] Furthermore, it should be noted that, provided that the angle between the axis of the first pipe segment 11 and the normal of the first reflective panel 14 is equal to the angle between the axis of the third pipe segment 13 and the normal of the first reflective panel 14, and the angle between the axis of the second pipe segment 12 and the normal of the second reflective panel 15 is equal to the angle between the axis of the third pipe segment 13 and the normal of the second reflective panel 15, one of the angles between the axes of the first pipe segment 11 and the third pipe segment 13, and the angle between the axes of the second pipe segment 12 and the third pipe segment 13, can be a right angle and the other can be an obtuse angle. This application does not limit this aspect.

[0105] In some embodiments, such as Figures 7 to 11 As shown, the fluid measurement pipeline structure also includes a control valve 105, which is installed in the fifth pipe section and is used to control the flow state of the fifth pipe section 17.

[0106] In this embodiment, the control valve 105 can be any type of valve structure, such as a ball valve, needle valve, or butterfly valve. Thus, when the control valve 105 is installed in the fifth pipe section, the flow state of the fluid in the fifth pipe section 17 can be controlled by the control valve 105, thereby controlling the flow state of the fluid from the fluid measurement pipeline structure and further improving the adaptability of the fluid measurement pipeline structure in application.

[0107] In some embodiments, the first pipe segment 11, the second pipe segment 12, the third pipe segment 13, the fourth pipe segment 16, the fifth pipe segment 17, the first reflective panel 14, and the second reflective panel 15 are integrally formed structures.

[0108] In this embodiment, since the first pipe section 11, the second pipe section 12, the third pipe section 13, the fourth pipe section 16, the fifth pipe section 17, the first reflective panel 14, and the second reflective panel 15 are integrally formed, the single-piece molding process reduces assembly errors, thereby improving the accuracy and sealing of the entire fluid measurement pipeline structure.

[0109] As can be seen from the above embodiments, in this embodiment, since the third pipe segment 13 is located between the first pipe segment 11 and the second pipe segment 12, and the third pipe segment 13 connects the first pipe segment 11 and the second pipe segment 12, the first pipe segment 11 and the second pipe segment 12 extend along the first direction, and the third pipe segment 13 extends along the second direction, the first direction and the second direction intersect, the end of the first pipe segment 11 away from the first reflective panel 14 has a first mounting groove 111, and the end of the second pipe segment 12 away from the second reflective panel 15 has a second mounting groove 121. The first mounting groove 111 and the second mounting groove 121 are both used to install transducers. Therefore, a fluid flow channel can be formed through the first pipe segment 11, the second pipe segment 12 and the third pipe segment 13, and an ultrasonic wave propagation channel can be formed simultaneously through the first pipe segment 11, the second pipe segment 12 and the third pipe segment 13, thereby reducing the manufacturing difficulty and manufacturing cost of the fluid measurement pipe structure.

[0110] Furthermore, since the first reflective panel 14 is located between the first pipe segment 11 and the third pipe segment 13, and the second reflective panel 15 is located between the second pipe segment 12 and the third pipe segment 13, the first pipe segment 11, the second pipe segment 12, the third pipe segment 13, the first reflective panel 14, and the second reflective panel 15 constitute an integral structure. The angle between the axis of the first pipe segment 11 and the normal of the first reflective panel 14 is equal to the angle between the axis of the third pipe segment 13 and the normal of the first reflective panel 14. The angle between the axis of the second pipe segment 12 and the normal of the second reflective panel 15 is equal to the angle between the axis of the third pipe segment 13 and the normal of the second reflective panel 15. Therefore, the first reflective panel 14 and the second reflective panel 15 required for ultrasonic wave propagation are directly formed from a part of the fluid flow channel, thereby reducing the structural complexity of the entire fluid measurement pipeline structure. Meanwhile, the first reflective panel 14 and the second reflective panel 15 are directly formed from a part of the fluid flow channel. On the one hand, this can reduce the obstruction to the fluid, reduce the pressure loss of the fluid, reduce the complexity of the fluid flow field, and thus improve the stability of the measurement. On the other hand, it can also prevent foreign objects from blocking the fluid flow channel, which facilitates the promotion and application of fluid measurement pipeline structures.

[0111] In some embodiments, such as Figure 14 As shown, this application embodiment also provides a fluid measuring device, which includes a first transducer 3, a second transducer 4, a control board 5, and a fluid measuring pipeline structure 1 according to any embodiment of the first aspect. The first transducer 3 is installed in a first mounting slot 111, and the second transducer 4 is installed in a second mounting slot 121. The first transducer 3 and the second transducer 4 are electrically connected to the control board 5 respectively.

[0112] In this embodiment, since the fluid measuring device includes the main pipe 2 and the fluid measuring pipe structure 1 of any of the above embodiments, the structure of the fluid measuring pipe structure 1 is simplified by reducing its structural complexity, thereby reducing the manufacturing cost of the fluid measuring device. Simultaneously, since the fluid measuring device can reduce obstruction to the fluid, reduce pressure loss, and decrease the complexity of the fluid flow field, the stability of the fluid measuring device's measurement can be improved. This also facilitates the widespread application of the fluid measuring device and expands its applicable range.

[0113] It should be noted that the first transducer 3 and the second transducer 4 can be any type of ultrasonic transducer, such as a piezoelectric transducer or an electromagnetic transducer. Thus, in the fluid measuring tube device of the above embodiment, when measuring water flow rate, the first transducer 3 installed in the first mounting slot 111 can act as an excitation transmitting transducer, and the second transducer 4 installed in the second mounting slot 121 can act as a receiving responding transducer. Conversely, the second transducer 4 installed in the second mounting slot 121 can act as an excitation transmitting transducer, and the transducer in the first mounting slot 111 can act as a receiving responding transducer. In this way, by controlling the first transducer 3 and the second transducer 4 to emit ultrasonic signals via the control board 5, the ultrasonic signal propagates faster and shorter in the direction of water flow, and slower and longer in the direction of water flow. By accurately measuring the time difference (i.e., time difference) of ultrasonic signal propagation in the downstream and upstream directions, the water flow velocity can be calculated. Then, by combining the geometry of the fluid measurement pipe with parameters such as water temperature and water pressure, the flow rate of the water currently flowing through the fluid measurement pipe can be calculated.

[0114] In some embodiments, such as Figure 15 As shown, this application embodiment also provides a fluid measurement system, which includes a main pipe 2 and a fluid measurement device 10 in a second aspect, wherein the main pipe 2 and the first pipe section 11 of the fluid measurement device 10 are connected.

[0115] In this embodiment, the main pipe 2 serves as the primary channel for the flow of the fluid to be measured. One end of the main pipe 2 is connected to a fluid supply source, and the other end is connected to the fluid measuring device 10. Thus, the main pipe 2 introduces the fluid into the measuring pipe of the fluid measuring device 10, allowing for fluid measurement. Given that the fluid measuring device 10 possesses advantages such as simplified structure, reduced manufacturing cost, and improved measurement accuracy, it not only facilitates installation of the fluid measuring device 10 within the fluid measuring system, thereby enabling its use in various environments, but also ensures that the fluid measuring system itself possesses the advantages of simplified structure, reduced manufacturing cost, and improved measurement accuracy. In an exemplary embodiment, the fluid measuring device 10 can be installed between the main pipe 2 and the water outlet component. The water outlet component can include any structure such as a faucet, spout, distributor, or nozzle; this embodiment does not limit the specific type of component. This makes it easier to measure the water output of the outlet component through the fluid measuring device 10. Due to the improved structure of the fluid measuring device 10, the cost of the fluid measuring device 10 is reduced, the stability and accuracy of fluid flow measurement are improved, and the application scenarios of the ultrasonic fluid flow measuring device are broadened, thus facilitating the promotion and application of this type of fluid measuring device 10.
