Abstract

The invention relates to the technical field of fluid flow measurement, in particular to a heat-insulating sound-conducting sound wave communication rod and a flow measurement device. The sound wave communication rod comprises a protective shell, a mounting clamp, a connecting part and a coupling protective sheet, a heat-insulating sound-conducting material is packaged in an inner cavity of the protective shell, the mounting clamp is arranged at the top end of the protective shell and used for being connected with an ultrasonic transducer, and the connecting part is arranged outside the protective shell and used for being connected with a measuring pipeline; the coupling protection piece is arranged at the bottom end of the protection shell to package the protection shell, and the bottom end of the sound wave communication rod extends into the measurement pipeline to make contact with fluid to be measured so as to conduct sound waves during use. The flow measuring device comprises an ultrasonic transducer, a sound wave communication rod and a locking device. The ultrasonic flowmeter can accurately measure the flow of high-temperature and low-temperature fluid in a pipeline, is good in heat insulation and sound conduction effect and convenient to operate, and can effectively solve the technical problem that an existing ultrasonic flowmeter cannot directly make contact with the high-temperature and low-temperature fluid and cannot measure the flow.

Description

technical field [0001] The invention relates to the technical field of fluid flow measurement, in particular to a heat-insulated and sound-conducting acoustic wave communication rod and a flow measurement device. Background technique [0002] Ultrasonic flowmeter is a device that uses the principle of time difference method to measure the flow of fluid in the pipe. It determines the flow of fluid in the pipe by measuring the time that the ultrasonic pulse travels between two ultrasonic transducers when the fluid is flowing forward and backward. The flow rate is calculated to obtain the flow rate of the fluid. In the process pipeline, the problem of measuring high temperature or low temperature fluid flow is often encountered. When the traditional ultrasonic flowmeter measures the fluid flow, it is easy to be damaged because the fluid temperature is too high (up to 600°C) or too low (as low as -140°C). Ultrasonic probes cause damage, which affects the measurement accuracy an...
