超声波大口径水表采用多声道同步测量，可以精确测量不同流层的水流速度，保证计量精度。
Product overview
The ultrasonic water meter is an all-electronic water meter obtaining water flow rate by analyzing and processing water speed by detecting the time difference caused by the change of velocity when the ultrasonic beam propagates along or adverse current. It has the characteristics of low start-up flow rate, wide range ratio and high measurement accuracy. Without movable parts and flow resistant elements in the meter body, as well as impact of impurities in the water, the meter has a long service life.
Multi-channel synchronous metering is adopted for the large-diameter ultrasonic water meter, enabling accurate measurement of water flow speed at different flow layers, so as to guarantee metering accuracy.
