Features

Remote Control & Alarm

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.

Platform Communication: Supports AEP/OneNet transparent transmission, UDP direct connection, and CT/CM/CU thing models; fully compatible with IoT platform NB-IoT meters for seamless switching.
Data Retransmission: Auto-retransmits failed data in next cycle; retransmission cycle and count configurable.
Reporting Frequency: 4 modes (daily, multiple times/day, every multiple days, specified dates).
Time-sharing Reporting: Prevents server congestion from a large number of simultaneous terminal reports.
Emergency Valve (Valve-controlled): Opens automatically in emergencies without network signal, maintaining water supply.
Overflow Valve Closing: Auto-closes when consumption exceeds set value; reopens manually to avoid waste from leakage or forgotten faucets.
