LoRaWAN Wireless Water Meter 15-25mm with 2.5-7.8 m³/h Flow Range and Class 2 Accuracy
This LoRaWAN IoT water meter features a mechanical and electrical separation design with integrated base meter, electric ball valve, magnetoresistive sensor, MCU, wireless communication module, and control circuitry. Powered by high-capacity lithium sub-battery packs, it ensures long-term stable operation for data acquisition, valve control, and wireless transmission.
Utilizing LoRaWAN wireless communication with spread spectrum technology, the meter automatically uploads water consumption data (default once daily) to LoRaWAN gateways, which then transmit to system data centers via LTE 4G or Ethernet networks.
- Split structure with independent electronic unit
- Non-contact full-electronic detection with 10-liter metering accuracy
- Touch key wake-up and long-press for remote data transmission
- Infrared communication interface for parameter configuration
- Comprehensive alarm functions for battery voltage, valve status, flow anomalies, and module failures
- Scheduled data collection and automatic upload (configurable timing)
- Auto switching between daily and monthly reporting modes based on signal conditions
- Low power design with sleep current under 10μA
- Automatic and remote clock calibration

The water meter automatically connects daily (configurable) to upload data and receive platform instructions. Touch the key area to wake the device or initiate immediate data transmission with a 3-second press.
• Regularly inspect water meters to prevent leakage accidents
• Implement winter insulation measures to prevent freezing and bursting
• Close upstream valves during extended unoccupied periods
• Water meters are precision measuring instruments - tampering is illegal
