Wireless Remote Water Meter

Wireless Remote Transmission Water Meter (with Valve)

Based on the enhanced design of mechanical multi-jet rotary water meters, it uses a damping plate for signal transmission. The signaling unit contains no magnetic components, giving it strong anti-magnetic interference capability.
For data communication, it supports LoRa transmission for computer login, sending and receiving data efficiently. In areas without base station coverage or for short-range use, data can also be collected via handheld devices.
With a non-contact structure, the counter section is vacuum-sealed and isolated from both external air and measured water, ensuring long-term clarity without fogging. The meter head is also waterproof-treated.
Using LoRa technology, the meter transmits key data such as flow rate, battery voltage, and signal strength to the meter reading system via a concentrator, enabling remote data collection, control, and fault alarm functions. Its split design includes an independently sealed electronic unit, ensuring stable operation while maintaining the accuracy and structure of traditional wet-type water meters.

Features
  • Double protection of structural sealing and potting glue sealing, with IP68
  • Mechanical and electrical separation structure design for convenient later maintenance
Applications
