ultrasonic water meter

Ultrasonic Water Meter

Ultrasonic water meter is a new type of water meter,With water temperature measurement,it has multiple output functions and can be connected with NB-IOT, LoRa,loRaWAN,GPRS, RS-485 and MBus transmission.


Ultrasonic water meter is a new type of water meter, which can detect the time difference caused by the change of velocity when the ultrasonic beam propagates along and against the current in the water, analyze the flow rate of the treated water, and further calculate the flow rate of the treated water. There are no moving parts inside, no current blocking elements, not affected by impurities in water, long service life.

Shengda water meter not only produce ultrasonic water meter,but also offer total solution for you,contains ultrasonic water meter,gateway/concentrator,free management software.
