Prepaid Direct Drinking Water Meter

This is a Smart water meter with Volumetric type and Rotary Type Water Meter as its base.
4G network/NB-IoT enables direct transmission of water meter-collected data (flow rate, temperature, signal strength) to the meter reading system, achieving data collection, remote control, and fault alarm.

Features
  • Electromechanical Synchronization Metering Function:
    Magnetoresistive sampling, 1L accuracy;
    The electronic section: equipped with bi-directional metering capability, synchronized with base meter to avoid disputes.
  • Network-wide Communication:
    Reporting Frequency: 4 modes (daily, multiple times/day, every multiple days, specified dates)；
    Data type: by default reports current real-time data;
    Can configure it to report historical data, and the number of historical data records to report and the sampling interval of historical data can be flexibly set.

Features

  • Overflow valve closing function: When the continuous water consumption of the water meter exceeds the set value, the valve automatically closes and automatically opens after manually activating the water meter, so as to avoid water resource waste caused by pipeline leakage or forgetting to turn off the faucet.
  • IP 68: The entire meter adopts triple waterproof sealing, a waterproof reducer, and the battery cavity is independently waterproof sealed, enabling normal operation in relatively humid environments.
  • Emergency Valve (Valve-controlled): Opens automatically in emergencies without network signal, maintaining water supply; The duration and number of valve openings for emergency valve opening can be set according to user requirements, facilitating later maintenance and management.
  • Abnormality alarm: In case of faults such as magnetic interference, battery power failure, and valve abnormality, the meter actively reports data to the system platform for timely early warning.
  • Record Query Function: The meter side can record the most recent setting command and operation time (such as manually setting meter readings, switching valves, etc.), and the recorded information of modified parameters can be read through the system platform and IR handheld devices, which can effectively solve the problem of data traceability when disputes arise.
