Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic flowmeters, in particular to a fast disassembly and assembly-capable fixing fixture for ultrasonic flowmeters. Background Art

[0002] An ultrasonic flow meter is an instrument that uses ultrasonic technology to measure the flow rate of a fluid. It is based on the principle that the propagation speed of ultrasound in a fluid is affected by the flow rate. It calculates the average flow rate of the fluid by measuring the difference in the propagation time of ultrasound in the downstream and upstream directions, and then obtains the flow rate. Existing ultrasonic flow meters usually need to be inserted into a pipe to detect the water flow rate during use. Since there is a certain impact force in the water flow inside the pipe and the flow meter lacks a certain supporting structure, the ultrasonic flow meter shakes during the detection process, affecting the accurate measurement of the ultrasonic signal and reducing the detection accuracy. Therefore, we propose a fast disassembly and assembly ultrasonic flow meter fixing fixture to solve the above problems. Utility Model Content

[0003] In order to overcome the existing ultrasonic flowmeter, it is usually necessary to insert it into the pipe to detect the water flow rate. Since there is a certain impact force in the water flow inside the pipe and the flowmeter lacks a certain supporting structure, the ultrasonic flowmeter shakes during the detection process, affecting the accurate measurement of the ultrasonic signal and reducing the detection accuracy.
