Wireless remote ultrasonic water meter

By measuring the velocity change of ultrasonic wave propagation in pipeline water flow, the velocity of water flow is deduced, and then the passing water flow is calculated. Equipped with Nb IOT mobile Internet of things module, it can realize the remote timing transmission and management of data according to the preset management strategy.
