Ultrasonic smart water meter is a fully electronic water meter that uses ultrasonic detection technology for water flow measurement, the digital display screen displays the measurement data in real time, and transmits the water meter data through the data communication interface.
Product features
■Unlimited installation Angle;
■Wide range ratio(R160/R200/R250/R400), High accuracy level, good stability;
■Multi transmission methods: Photoelectric、RS-485、M-Bus、LoRa、NB-IoT,etc.
■No mechanical transmission parts、wear-free.
■Low startup flow rate(Startup flow rate can reach 0.0015m³/h).
■With water temperature measurement function.
■The whole water meter is designed with IP68, which can work under water for a long time.
■ Micro-power technology, battery power (measurement cycle 1s, battery theoretical work more than a decade).
■
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 first time.
