Abstract

The invention discloses an ultrasonic measuring device. The ultrasonic measuring device comprises a master measuring sensor and a slave measuring sensor, wherein the master measuring sensor comprises a first shell, and a first transduction element, a measuring and processing element and a signal control element arranged inside the first shell; the signal control element is connected with the first transduction element and the measuring and processing element respectively; the first transduction element is arranged on the bottom end face of the first shell; the slave measuring sensor comprises a second shell and a second transduction element arranged on the bottom end face of the second shell; the second transduction element is connected with the signal control element. By adopting the ultrasonic measuring device, signals acquired by the master measuring sensor and the slave measuring sensor do not need to be transmitted by a long distance, so that errors caused by transmission delay of signals can be reduced while a transmission line is saved and the spatial structure of the measuring device is reduced, the influences of the unstable factors of the external environment on signal transmission can be effectively avoided, and the reliability and measuring accuracy of the ultrasonic measuring device are improved.

Description

Technical field

[0001] The invention relates to the technical field of measurement, in particular to an ultrasonic measuring device.

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 piezoelectric ceramic sheets. conversion between each other.

[0003] The ultrasonic sensor needs to transmit the collected pulse signal to the hardware circuit system (flow processing equipment) for calculation and processing, in order to obtain the flow signal. The ultrasonic sensor is separated from the hardware circuit system and connected by signal line transmission. Not only the assembly space...
