Products Description
Main advantage
1. Integrated R400/R250 dynamic range ultrasonic technology can achieve ultra-high precision, detecting flow rates as low as 2L/h.
2. U0/D0 hydraulic design, supporting installation in any space.
3. IP68 level structure ensures a service life of over 15 years
4. Composite material structures made of brass and plastic, which are hard, corrosion-resistant, and permanently maintain performance
5. The NRW of LoRaWAN module decreased by 18% in AMI network.
