[0002] In the field of industrial metrology, the technology of measuring fluid flow using ultrasonic principles has been widely applied. The core measuring element, the ultrasonic transducer, is a precision device that typically needs to be fixedly installed on the measuring pipe section and in direct contact with the fluid being measured for extended periods. In practical applications, impurities or corrosive components in the fluid can easily cause wear or corrosion on the acoustic face of the transducer, leading to a decrease in acoustic performance and measurement accuracy, ultimately affecting the accuracy and reliability of the flow data. Furthermore, traditional transducer installation methods often employ a fixed structure. When a single transducer fails, the entire measuring pipe section often needs to be disassembled and replaced, a cumbersome process with high maintenance costs. Therefore, existing technologies suffer from the problem of the ultrasonic transducer being non-removable or inconvenient to replace, affecting the long-term operational stability and economy of the entire flow measurement device. Utility Model Content

[0003] Given that existing technologies suffer from the problem that the ultrasonic transducer cannot be replaced individually, leading to increased maintenance costs and affecting the long-term operational stability and economy of the flow measurement device, this utility model aims to provide a transducer-removable clamp-on ultrasonic flow meter that allows for convenient, quick, and timely replacement of damaged ultrasonic transducers, ensuring continuous accuracy and reliability of measurement data, and improving the practicality, maintenance convenience, and economy of the equipment.

[0004] This utility model provides a transducer detachable clamp-on ultrasonic flow meter, including a measuring pipe section, two transducer mounting assemblies symmetrically installed on the measuring pipe section, and a detachable ultrasonic transducer inserted into the transducer mounting assembly. The transducer mounting assembly includes: a transducer mounting base integrally formed with the measuring tube section, two transducer mounting holes opened in the transducer mounting base, slots respectively provided on both sides of the transducer mounting base, and a limiting baffle inserted and installed in the slot, wherein the limiting baffle is provided on the outside of the ultrasonic transducer.

[0010] Furthermore, gaskets for sealing are provided at both ends of the measuring tube section.

[0011] Furthermore, several screw mounting seats are installed on the outer side of the measuring pipe section. Long screws pass through the screw mounting seats and are fixedly connected to the flanges of the two pipe sections on both sides of the measuring pipe section. The gasket is clamped between the measuring pipe section and the flanges of the two pipe sections on both sides. Several protrusions are distributed on the gasket, and the two ends of the measuring pipe section are provided with mating grooves corresponding to the protrusions.

[0026] Please refer to Figures 1-6 This utility model provides a transducer detachable clamp-on ultrasonic flow meter, including a measuring pipe section 1, two transducer mounting assemblies 2 symmetrically installed on the measuring pipe section 1, and a detachable ultrasonic transducer 3 inserted into the transducer mounting assembly 2.

[0027] The transducer mounting assembly 2 includes: a transducer mounting base 21 integrally formed with the measuring tube section 1, two transducer mounting holes 22 opened in the transducer mounting base 21, slots 23 respectively set on both sides of the transducer mounting base 21, and a limiting baffle 24 inserted and installed in the slots 23. The limiting baffle 24 is set on the outside of the ultrasonic transducer 3.

[0028] Furthermore, the transducer mounting base 21 is equipped with a removable housing cover 26.

[0029] Furthermore, the limiting baffle 24 is provided with a disassembly groove 241, which is used to slide the limiting baffle 24 out of the slot 23.

[0030] In this embodiment, transducer mounting components 2 are symmetrically arranged in the measuring pipe section 1, and ultrasonic transducers 3 are adapted and installed in the transducer mounting holes 22. The ultrasonic transducers 3 are reliably fixed by the limiting baffles 24 in the sliding grooves 23, thereby ensuring the stability of ultrasonic signal transmission. As a precision component, the ultrasonic transducer 3 is in long-term contact with flowing fluid, which can easily lead to wear of the acoustic end or corrosion by the fluid, thus affecting the measurement accuracy and causing data deviation. This patent designs the ultrasonic transducer 3 as a detachable structure, which facilitates quick and timely replacement in case of damage, effectively extending the service life of the device, ensuring continuous accuracy and reliability of measurement data, and improving the practicality, maintenance convenience, and economy of the equipment.

[0031] In this embodiment, two ultrasonic transducers 3 are respectively inserted into two transducer mounting holes 22, and then two limiting baffles 24 are respectively inserted into the slots 23 to limit and fix the ultrasonic transducers 3, ensuring the stability of the installation of the ultrasonic transducers 3, further ensuring the transmission and reception of signals by the ultrasonic transducers 3, and ensuring the accuracy and stability of the flow signal.

[0032] To further clarify, the ultrasonic transducer 3 is a precision measuring component and needs to be replaced promptly after a period of use to ensure the accuracy of flow detection. When the ultrasonic transducer 3 needs to be replaced, the operator removes the outer cover 26, then manually moves the limiting baffle 24 through the disassembly slot 241 to slide it out of the slot 23. Then, the ultrasonic transducers 3 in the two transducer mounting holes 22 are removed respectively, and the new ultrasonic transducers 3 are reinstalled in the two transducer mounting holes 22 respectively. The two limiting baffles 24 are reinstalled in the slots 23 respectively. Finally, the outer cover 26 is reinstalled on the transducer mounting base 21, and the replacement of the ultrasonic transducer 3 is completed.

[0033] Furthermore, the limiting baffle 24 can unlock or lock the ultrasonic transducer 3 by sliding it into or out of the slot 23, which is useful for the installation and removal of the ultrasonic transducer 3.

[0034] Furthermore, a sealing gasket is provided inside the transducer mounting hole 22. The sealing gasket not only ensures the stability of the ultrasonic transducer 3 installation, but also ensures that the fluid flowing in the measuring tube section 1 will not leak from the transducer mounting hole 22, ensuring the safety of the components inside the transducer mounting base 21, and further ensuring the smooth flow of fluid in the measuring tube section 1.

[0035] like Figure 3 and Figure 5 As shown, the ultrasonic transducer 3 is provided with a positioning protrusion 31, and the transducer mounting hole 22 is provided with a positioning groove 25 that cooperates with the positioning protrusion 31 for installation.

[0036] In this embodiment, the rotation of the ultrasonic transducer 3 is restricted by the cooperation of the positioning protrusion 31 and the positioning groove 25, so that the acoustic end of the ultrasonic transducer 3 is set at a fixed angle, further ensuring that the ultrasonic transducer 3 can stably and timely receive or transmit signals.

[0037] like Figure 5 As shown, the acoustic end of the ultrasonic transducer 3 is an inclined surface 32, and the inclined surfaces 32 of the ultrasonic transducers 3 in the two transducer mounting assemblies 2 are arranged obliquely opposite each other.

[0038] In this embodiment, the ultrasonic transducer 3 can be used as either a signal transmitter or a signal receiver. The two ultrasonic transducers 3 installed in the transducer mounting assembly 2 have their inclined surfaces 32 arranged in a V-shape facing each other. The ultrasonic transducer 3 that serves as the signal transmitter and the ultrasonic transducer 3 that serves as the receiver have their inclined surfaces 32 facing each other and are respectively installed in different transducer mounting assemblies 2. The receiving end and the transmitting end of the two sets of ultrasonic transducers 3 are arranged obliquely and alternately, which can obliquely measure data such as the flow velocity of the fluid flowing through the pipe, and the two sets of data are compared to further verify the accuracy of the data.

[0039] like Figure 1 and Figure 6 As shown, gaskets 4 for sealing are provided at both ends of the measuring tube section 1.

[0040] Furthermore, several screw mounting seats 5 are installed on the outer side of the measuring pipe section 1. Long screws pass through the screw mounting seats 5 and are fixedly connected to the flanges of the two pipe sections on both sides of the measuring pipe section 1. Gaskets 4 are clamped between the measuring pipe section 1 and the flanges of the two pipe sections on both sides. Several protrusions 41 are distributed on the gaskets 4. Both ends of the measuring pipe section 1 are provided with mating grooves 11 corresponding to the protrusions 41.

[0041] In this embodiment, the measuring tube segment 1 is placed between the two tube segments, and a long screw is used to clamp and fix the measuring tube segment 1 through the mounting flange and screw mounting seat 5 of the two tube segments. This structure achieves a sealed clamping by using gaskets 4 on both sides of the measuring tube segment 1, which not only eliminates the need for screw connections between the measuring tube segment 1 and the two tube segments, simplifying the installation process and improving assembly efficiency, but also enhances the overall sealing performance. The design of the gaskets 4 increases the friction between the contact surfaces of the measuring tube segment 1 and the two tube segments, further strengthening the sealing effect. In addition, several protrusions 41 are distributed on the gaskets 4, which are embedded into the mating grooves 11 at the ends of the measuring tube segment 1, making the two fit more tightly and effectively improving the sealing reliability of the connection.

[0042] like Figure 3 As shown, the upper side wall of the transducer mounting base 21 has a through hole 27 for the data transmission line to pass through.

[0043] To further explain, a flow meter head 6 for reading measurement data is installed on the measuring pipe section 1, and the data transmission line of the ultrasonic transducer 3 passes through the wire hole 27 and is connected to the flow meter head 6.

[0044] In this embodiment, the data from the ultrasonic transducer 3 can be transmitted to the flow meter head 6 via the data transmission line through the wire hole 27, and the data is processed and displayed through the flow meter head 6. At this time, the testing personnel can accurately and clearly read the flow rate and other values ​​displayed on the flow meter head 6.

[0045] 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.
