Ultrasonic water meter is a new type of water meter that can be used to analyze and deal with the time difference caused by the change of velocity when an ultrasonic beam propagates downstream and counter-current in water, so as to further calculate the discharge of water.
Features: low initial flow rate, wide range ratio, high measuring accuracy, and stable operation.
No internal moving parts open flow components, not affected by impurities in water, long service life. The output communication function is complete, meeting all kinds of communication and wireless networking requirements.
With excellent small-flow detection ability, it can solve the problems of many traditional water meters. It is more suitable for gradient charging of water charges, more suitable for saving and rational utilization of water resources, and has a broad market and uses prospects.
An ultrasonic water meter is an electronic water meter made of industrial electronic components based on the principle of ultrasonic time difference. Compared with a mechanical water meter, it has the characteristics of high precision, good reliability, wide range ratio, long service life, no moving parts, no need to set parameters, and installation at any Angle.
