4G Smart Water Meter (without Valve)

This is a new type of smart water meter that uses a Rotary Type Water Meter as its base.
Internal structure: Equipped with an integrated communication module and SIM card. 4G network 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.
External structure(A split design): the electronic unit is installed in an independent fully sealed cavity, with a waterproof performance of IP68 rating. It maintains the structure and accuracy of traditional wet-type water meters.

Features
  • Mechanical & Electrical Design: Modular structure (mechanical & electronic parts), screw-assembled for easy maintenance
  • Network Coverage: NB & 4G hybrid, wide coverage for rural, urban, indoor scenarios
  • Communication: Direct base station connection, supports CT AEP, CM OneNET, UDP protocols

Features

  • 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.
  • IP68 protection grade: Adopts a dual protection design of structural sealing and potting sealing, with good waterproof performance.
  • Parameter setting function: Meter-end parameters can be set through the external IR port and the pre-machine system.
  • Touch wake-up function: The meter end has a wake-up function; uploading can be triggered by touching the button or magnetic wake-up switch for more than 3 seconds, and the IR communication function is turned on at the same time.
  • Periodic reporting function: The meter has optional daily scheduled reporting, interval reporting, and on-the-hour reporting functions.
  • Data retransmission function: When the current data reporting is unsuccessful, the data will be automatically re-transmitted in the next retransmission cycle; the retransmission cycle and number of retransmissions can be set;
  • Large-caliber IoT Water Meter has a disconnection alarm function (split type).
