Description

Technical Field

[0001] This utility model relates to the field of ultrasonic flow meter technology, specifically to an ultrasonic flow meter with a detachable transducer module. Background Technology

[0002] As an important flow measurement instrument, ultrasonic flow meters have been widely used in industrial production, water conservancy measurement and other fields due to their advantages such as non-contact measurement, high accuracy and low pressure loss.

[0003] As a crucial detection element in ultrasonic flow meters, the performance and installation stability of the ultrasonic transducer directly determine the accuracy and reliability of flow measurement. Current ultrasonic flow meters often employ a fixed connection or integrated design between the ultrasonic transducer and the measuring pipe section. This means that when the ultrasonic transducer malfunctions or requires periodic calibration, operators often need to disassemble the entire pipe section or perform tedious cutting and re-welding operations. This installation and disassembly process is not only complex and labor-intensive but also leads to extended maintenance and downtime, further increasing maintenance costs. In some cases, it may even necessitate interrupting fluid transport or monitoring to replace the pipe section, directly impacting production efficiency and the continuity of data monitoring. Utility Model Content

[0012] Furthermore, a flow meter head for reading measurement data is installed on the measuring pipe section, and the data transmission line of the ultrasonic transducer passes through the wire hole and is connected to the flow meter head.

[0013] Furthermore, a removable outer cover is provided on the outside of the transducer mounting base.

[0014] Furthermore, one end of the measuring pipe section is installed to a fluid pipeline on one side via a fixed flange, and the other end is installed to a fluid pipeline on the other side via a split flange. The split flange includes a first half flange and a second half flange that are interlocked and installed together. The first half flange and the second half flange are detachably and separately installed at the end of the measuring pipe section.

[0028] Please refer to Figures 1-5 This utility model provides an ultrasonic flow meter with a detachable transducer module, comprising a measuring pipe section 1, a mounting base 6 symmetrically mounted on the measuring pipe section 1, and a detachable transducer module 2 mounted on the mounting base 6 via a mounting component 7.

[0029] The transducer module 2 includes: a transducer mounting base 21 installed on the side of the measuring tube section 1, two transducer mounting holes 22 opened on the transducer mounting base 21, an ultrasonic transducer 23 disposed in the transducer mounting holes 22, and a transducer fixing member 24 installed on the outside of the ultrasonic transducer 23, wherein the ultrasonic transducer 23 abuts against the transducer fixing member 24.

[0030] To further explain, the transducer fixing part 24 is installed with the transducer mounting hole 22 through a threaded engagement.

[0031] Furthermore, a removable housing cover 25 is provided on the outer side of the transducer mounting base 21.

[0032] This embodiment achieves detachable installation of the transducer module 2 relative to the measuring pipe section 1 by detachably mounting the transducer module 2 onto the mounting base 6. This improves the overall maintainability and application flexibility of the ultrasonic flowmeter, allowing for rapid inspection and regular maintenance of the transducer module 2 without disassembling the pipe section or affecting the overall system structure. Furthermore, the separate design of the ultrasonic transducer 23 and the transducer mounting base 21 allows for timely replacement of faulty components within the transducer module 2, enhancing the flexibility and convenience of maintenance operations. This improves the accuracy of the detection results, effectively shortens the maintenance cycle and reduces manpower input, providing a solid guarantee for the continuity and reliability of flow monitoring data. Specifically, the ultrasonic transducer 23 is installed within the transducer mounting hole 22, and the transducer fixing component 24 ensures its stable installation, further guaranteeing stable operation under vibration or complex conditions. This ensures the consistency and accuracy of ultrasonic signal transmission and reception, improving the accuracy and reliability of flow detection data.

[0033] In this embodiment, the ultrasonic transducer 23 is inserted into the transducer mounting hole 22. A first threaded ring 221 is provided on the inner wall of the transducer mounting hole 22, and a second threaded ring 241 that mates with the first threaded ring 221 is provided on the outer side of the transducer fixing member 24. Through the tight engagement of the first threaded ring 221 and the second threaded ring 241, the transducer fixing member 24 is tightly abutted against the outer side of the ultrasonic transducer 23, thereby achieving a stable lock of the ultrasonic transducer 23, effectively suppressing external vibration and positional displacement, ensuring the stability of the ultrasonic transducer 23, further ensuring the stability of the ultrasonic transducer 23 during operation, and thus ensuring the consistency and accuracy of the ultrasonic transducer 23 in receiving or transmitting ultrasonic signals, enhancing ultrasonic response performance, and improving the accuracy and reliability of detection data.

[0034] Furthermore, the transducer module 2 and the mounting base 6 are detachable. The two transducer modules 2 are symmetrically installed on the mounting base 6 through the cooperation of several mounting parts 7. Since the measuring pipe section 1 is installed in the middle of the pipe to be measured by bolts, when the ultrasonic transducer 23 has problems such as inaccurate data, wear of the acoustic end face, or excessive service life, directly replacing the measuring pipe section 1 is not only cumbersome and uneconomical, but also requires a lot of time for adjustment and installation, which is time-consuming and labor-intensive. By setting the transducer module 2 as a detachable component, it can be directly disassembled for replacement with the same model. The operator does not need to disassemble the entire measuring pipe section 1, which greatly simplifies the maintenance process, significantly shortens the repair and replacement time, and effectively ensures the continuity of measurement and the reliable operation of the system.

[0035] As a preferred embodiment, the mounting component 7 can be a screw, which enables the transducer module 2 and the mounting base 6 to be detachably installed. Furthermore, other components that can achieve the above effects can also be used here, and this patent does not limit the selection of the mounting component 7.

[0036] like Figures 2-5 As shown, the transducer mounting hole 22 is set at a relative angle, and the ultrasonic transducer 23 is inserted and installed in the transducer mounting hole 22.

[0037] To further clarify, the acoustic end faces of the two obliquely arranged ultrasonic transducers 23 are arranged opposite each other.

[0038] In this embodiment, the ultrasonic transducers 23 can all be used as either the transmitting or receiving ends of ultrasonic waves. The acoustic end faces of the ultrasonic transducers 23 are all horizontal straight surfaces. Since the transducer mounting holes 22 are angled, the ultrasonic transducers 23 inserted therein are angled and oppositely positioned. Therefore, the acoustic end faces of the two ultrasonic transducers 23 are precisely opposite each other, with one serving as the transmitting end of the ultrasonic wave and the other as the receiving end. This is used to detect the fluid flowing through the measuring pipe section 1, which not only effectively enhances the propagation efficiency of ultrasonic waves in the fluid but also significantly improves the signal strength. Furthermore, by obliquely penetrating the fluid, the propagation path in the medium is significantly extended, making it more sensitive to changes in flow velocity. This is especially suitable for the accurate measurement of low-velocity or impurity-containing fluids.

[0039] Furthermore, by the coordinated operation of four ultrasonic transducers 23 respectively set in the two transducer modules 2, alternatingly emitting and receiving ultrasonic waves, bidirectional flow detection of the fluid flowing through the measuring pipe section 1 is achieved. This effectively suppresses interference caused by uneven flow field distribution and can compensate for changes in sound velocity caused by temperature and pressure fluctuations, further improving the accuracy of the detection data, reducing measurement errors, and making the output data more stable and reliable.

[0040] like Figure 4 As shown, the mounting base 6 is integrally formed with the measuring tube section 1. The mounting base 6 has an elongated hole 61 for mounting the transducer module 2. The elongated hole 61 is connected to the inner cavity of the measuring tube section 1. The transducer mounting base 21 is provided with a mounting protrusion 211 that is inserted into the elongated hole 61.

[0041] In this embodiment, by engaging the mounting protrusion 211 into the elongated hole 61, a tight fit is achieved between the transducer mounting base 21 and the measuring tube segment 1, effectively suppressing possible displacement and vibration during operation and improving the overall integrity and structural rigidity of the installation. Furthermore, the multi-point locking of the mounting component 7 assists in the installation, enhancing the connection strength between the transducer module 2 and the measuring tube segment 1. This not only effectively avoids measurement deviations caused by loosening but also ensures the stability of signal transmission under complex working conditions, thus providing a solid structural foundation for the accuracy and reliability of the detection data.

[0042] To further explain, when it is necessary to replace the transducer module 2, the transducer module 2 can be removed from the mounting base 6 by loosening the mounting piece 7. At this time, the mounting protrusion 211 is separated from the elongated hole 61. Then, the transducer module 2 can be replaced as a whole, or the transducer module 2 can be disassembled to replace or repair its internal parts. Specifically, open the outer cover 25, then unscrew the transducer fixing piece 24 from the transducer mounting hole 22, and take out the ultrasonic transducer 23 from the transducer mounting hole 22. At this time, the disassembly of the transducer module 2 is completed, and the damaged components can be replaced as appropriate. After replacement, reassemble into a new transducer module 2 in sequence. Then, align the mounting protrusion 211 with the elongated hole 61 and install the new transducer module 2 on the measuring tube section 1 through the mounting piece 7.

[0043] like Figure 2 As shown, the upper side wall of the transducer mounting base 21 has a through hole 212 for the data transmission line to pass through.

[0044] To further explain, a flow meter head 3 for reading measurement data is installed on the measuring pipe section 1, and the data transmission line of the ultrasonic transducer 23 passes through the wire hole 212 and is connected to the flow meter head 3.

[0045] In this embodiment, the data collected by the ultrasonic transducer can be stably transmitted to the flow meter head 3 through the data transmission line via the wire hole 212. The flow meter head 3 performs rapid processing and analysis of the signal and finally presents key information such as flow rate clearly and accurately on the display screen. At this time, the testing personnel can accurately and clearly read the values ​​such as flow rate displayed on the flow meter head 3, further improving the convenience and reliability of on-site testing.

[0046] like Figure 1 As shown, one end of the measuring pipe section 1 is installed with a fluid pipeline on one side via a fixed flange 4, and the other end is installed with a fluid pipeline on the other side via a split flange 5. The split flange 5 includes a first half flange 51 and a second half flange 52 that are interlocked. The first half flange 51 and the second half flange 52 are detachably installed at the end of the measuring pipe section 1.

[0047] In this embodiment, the fixed flange 4 is fixedly installed at one end of the measuring pipe section 1, and the split flange 5 is installed at the other end of the measuring pipe section 1 through the mounting groove. When installing the measuring pipe section 1, after fixing the fixed flange 4 to the fluid pipeline on one side with screws, the first half flange 51 and the second half flange 52 of the split flange 5 are separated. First, the first half flange 51 is installed in the mounting groove, rotated to align the first half flange 51 with the fluid pipeline, and then fixed with screws. Then, the second half flange 52 is installed into the mounting groove, adjusted slightly to align it with the fluid pipeline, and then fixed with screws. Finally, the first half flange 51 and the second half flange 52 are fixedly installed, completing the fixed installation of the measuring pipe section 1 with the fluid pipelines on both sides.

[0048] Furthermore, the split flange 5 can be adapted to the angle rotation and alignment of the fluid pipeline, providing strong flexibility. In addition, the split flange 5 can be disassembled for easy cleaning. The method of separation and rotation alignment can conveniently and efficiently achieve the fixed installation of the measuring pipe section 1 and the fluid pipelines on both sides.

[0049] It should be understood that the specific embodiments described above are only for explaining the present invention and are not intended to limit the present invention. Obvious variations or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
