The development principle of ultrasonic water meter is propagation velocitdifference method, it has the functions of measurement, calculation and display. luses micro-power technology, so that only a small amount of flow is consumed inaccurate measurement. Ultrasonic water meter also has the characteristics of smallsize, high stability and strong anti-interference ability.Its design conforms to GB /T 778-2018 “Drinking cold water meter and hot watermeter
◎ |P68 protection level of the whole machine, can work in water for a long time.
◎ Using ultrasonic flow measurement technology, can realize multi-angle installation
◎ Support communication with the loT platform through the NB-loT network to realiz.
data upload and download.
◎ Small size, high stability, long service life
