What Is Ultrasonic Water Meter

    Ultrasonic water meter is a new type of water meter that detects the time difference caused by changes in velocity during the propagation of ultrasonic sound beams in water, analyzes and processes the flow rate of effluent, and further calculates the volume of effluent. What is the working principle of an ultrasonic water meter?

    The ultrasonic water meter adopts the time difference method to measure the volume, which means installing an ultrasonic transducer upstream and downstream of the measurement channel (pipe section) for mutual transmission and reception of ultrasonic signals.

    Due to the superposition of ultrasonic signals and water flow signals, the propagation speed of sound waves in the downstream and upstream directions is different. Therefore, the ultrasonic signals emitted by the two transducers have different operating times in water. By measuring the difference in time, the flow velocity of the fluid can be calculated, and then converted into volume to achieve volume measurement.

    There is a set of transducers in the measuring tube. The A transducer emits an ultrasonic signal (downstream) to the B transducer, while the B transducer emits an ultrasonic signal (upstream) to the A transducer. The upstream and downstream ultrasonic signals form a certain time difference during transmission. Under the conditions of the calibrated cross-sectional area of the pipe diameter and the length of the standard measuring tube, the volume of water output is calculated using the calculation chip on the integrator.
