The pipeline ultrasonic flowmeter uses the principle of ultrasonic time difference to measure the flow rate of liquid in a circular pipe. The ultrasonic water meter produced by our company uses industrial grade electronic components, powered by batteries, without mechanical rotation, wear, or pressure loss. It is a fully electronic industrial water meter. Ultrasonic water meters have the advantages of high accuracy, good reliability, low price, and long service life. It can completely replace other types of water meters.
