Main Features:
-- No mechanical movable parts，Impurities in water can't be affected, Long service life.
-- Compared with the traditional mechanical water meter, the ultrasonic water meter can be measured and has wide range of measurement . 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.
