Problems solved by technology

[0004] The present invention aims at the fact that the two ultrasonic probes in the existing ultrasonic water meter need to transmit and receive ultrasonic waves at the same time, the structure of the ultrasonic probe is complex and the volume is large, and the edge of the ultrasonic probe will cause a certain blockage and disorder of the water flow, which will cause measurement errors and detect the water flow. The position is the center of the water flow, which causes the detected flow velocity and water flow to be greater than the actual value. An ultrasonic water meter is proposed

Abstract

The invention discloses an ultrasonic water meter. It includes a water inlet section, a water outlet section and a measurement section; it is characterized in that: one end of the measurement section is equipped with an ultrasonic generator, and the other end is equipped with an ultrasonic receiver, the ultrasonic generator generates and emits ultrasonic waves and records the emission time, and the The ultrasonic receiver receives ultrasonic waves and records the receiving time. The invention solves the problem that two ultrasonic probes in the existing ultrasonic water meter need to transmit and receive ultrasonic waves at the same time, the structure of the ultrasonic probe is complex and the volume is large, and the edge of the ultrasonic probe will block and disturb the water flow to a certain extent, causing measurement errors and detecting water flow. The location is the technical problem at the center of the water flow that causes the detected flow rate and water flow to be greater than the actual value.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic water meters, in particular to an ultrasonic water meter. Background technique [0002] The existing ultrasonic water meter is composed of several parts such as an ultrasonic probe, a signal processing unit, and a display unit. Two opposing ultrasonic probes deployed in the pipeline transmit and receive ultrasonic waves at the same time, and calculate the current water flow velocity based on the time difference between the two ultrasonic probes receiving the ultrasonic waves, and then calculate the instantaneous water flow rate based on the cross-sectional area of ​​the section. The existing ultrasonic water meter structures are divided into V-type, W-type, X-type and Z-type. Among them, V-type and W-type ultrasonic water meters need to rely on pipe wall reflection, which has poor signal direction characteristics, large sound wave loss, and large measurement errors. ; The sound channel of the ...
