Performance characteristics
— No mechanical movable parts, Impurities in water can’t be affected, and Long service life.
— Compared with the traditional mechanical water meter, the ultrasonic water meter can be measured and has a wide range of measurements. It can be measured when it has very small traffic.
— There are many alarm functions: Battery voltage can alarm, empty tubes or pipes that are not full of water, transducer fault alarm, and more
— Low-power design and the use of high-energy batteries, can work for 6 years or more.
— The communication interface is M-BUS and Rs485, it can easily achieve remote real-time monitoring and management on the LAN.
