LoRaWAN Smart Water Meter with 15-25mm Nominal Caliber, 2.5-7.8 m³/h Flow Range and Wireless Remote Monitoring
This LoRaWAN IoT water meter combines mechanical water meter base with electronic components including electric ball valve, magnetoresistive sensor, MCU, wireless communication module, and control circuit. Featuring mechanical-electrical separation design and powered by high-capacity lithium sub-battery pack, it ensures long-term stable operation for data acquisition, valve control, and wireless transmission.
The dry structure design isolates the counting mechanism from measured water, preventing fogging and condensation issues common in wet meters. Using LoRaWAN wireless communication with spread spectrum technology, it automatically uploads user water data daily to the LoRaWAN gateway, which then transmits to the system data center via LTE 4G or Ethernet.
- Split structure with independent electronic unit and base meter
- Non-contact full-electronic detection with 10-liter metering accuracy
- Touch key wake-up and long-press key for remote data transmission
- Infrared communication interface for parameter reading and setting
- Multiple alarm functions for battery voltage, valve status, flow anomalies, and metering failures
- Timed data collection and automatic upload (default once daily)
- Automatic switching between daily and monthly reporting modes based on signal conditions
- Low power design with 3.6V lithium battery and sleep current under 10μA
- Automatic and remote platform time calibration

Important Notes:
- Regularly inspect water meters to prevent leakage accidents
- Install insulation measures in winter to prevent freezing and bursting
- Close the front valve when property is unoccupied for extended periods
- Water meters are measuring instruments - tampering is illegal
18-month free repair or replacement warranty when installation and operation guidelines are followed. Full lifecycle support including technical documentation, wiring diagrams, maintenance training, and regular software updates.
