Description

【Technical field】 [0001] The invention relates to the technical field of flow measurement, in particular to an ultrasonic measurement system and a measurement method thereof. 【Background technique】 [0002] The ultrasonic flowmeter is referred to as USF (ultrasonic flowmeter), which is a device that measures the volume of the fluid according to the change in the propagation speed of the ultrasonic beam when the fluid flows. Ultrasonic flowmeters usually include two ultrasonic sensors, which are the receiving and emitting sources of ultrasonic signals and electrical signals. Each ultrasonic sensor includes a shell and a piezoelectric ceramic sheet. The piezoelectric ceramic sheet makes the lower end of the shell The end face vibrates to generate ultrasonic waves. When the ultrasonic sensor is used for flow measurement, the received signal is transmitted to the flow processing device through the connection line between the ultrasonic sensor and the flow processing device. ...
