Products Features

The features of this series of SMART water meters are summarized as follows:

1. Unlimited installation Angle;

2. Wide range ratio(R160/R200/R250/R400), High accuracy level, good stability;

3. Multi-transmission methods: Photoelectric,RS-485,M-Bus,LoRa,NB-IoT,etc.

4.No mechanical transmission parts,wear-free.

5.Low startup flow rate(Startup flow rate can reach 0.0015m³/h).

6. With water temperature measurement function.

7. The whole water meter is designed with IP68, which can work underwater for a long time.

8. Micro-power technology, battery power (measurement cycle 1s, battery theoretical work more than a decade).

9. Highly intelligent self-checking capability, monitoring common problems such as empty pipes, air bubbles, transducer aging, battery Undervoltage, abnormal water temperature (too high or too low), abnormal water volume (leaking or running water), and other problems (above functions are Optional), can adopt NB-IoT technology, and push information to users at the first time.
