Features

4G Communication with Waterproof Split Structure

Equipped with an integrated communication module and SIM card, the 4G network enables direct transmission of water meter data (flow rate, temperature, signal strength) to the meter reading system for data collection, remote control, and fault alarms. The external split design places the electronic unit in an independent fully sealed cavity with IP68 waterproof performance, while maintaining the structure and accuracy of traditional wet-type water meters.

Measurement: Non-magnetic/magnetoresistive sampling, accuracy 1L/10L; The electronic section: equipped with bi-directional metering capability, synchronized with base meter to avoid disputes.
Emergency Valve (Valve-controlled): Opens automatically in emergencies without network signal, maintaining water supply.
Multiple modes of Data Reporting: daily, N times/day, every N days, specified dates; N≥2.
Time-sharing Reporting: Prevents server congestion from a large number of simultaneous terminal reports.
Abnormality Alarm: Alerts for power failure, sensor faults, valve faults.
Prepaid Function (Valve-controlled): Enables back-end prepaid with upper system.
