The development principle of ultrasonic water meter is propagation velocity difference method,it has the functions of measurement,calculation and display.It uses micro-power technology,so that only a smallamount of flow is consumed in accurate measurement.Ultrasonic water meter also has the characteristics of small size,high stability and strong anti-nterference ability.
Its design conforms to GB/T 778-2018″Drinking cold water meter and hot water meter.
◎ IP68 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-IoT network to realize data upload and download.
◎ Small size,high stability,long service life.
