Prepaid Water Meter

IC Card Cold type Water Meter

IC Card Cold type Water Meter /IC Card Hot type Water Meter uses a Rotary Wet type Water Meter as its base.
Adopts the electromechanical conversion method of pulse magnetoresistive counting function, completes data transmission via IC card and Bluetooth, and is suitable for occasions where users have the requirement of mobile phone recharge for prepayment before water usage.

Features
  • HD LCD: shows purchased water volume, remaining volume, cumulative consumption, valve status, battery status, etc.
  • Prepayment: Pay-first usage; auto-closes valve when out of credit, auto-opens after recharge.
  • Mechanical and electrical separation design: convenient for maintenance in the later stage.
Applications

Residential

Features

  • Prompt & Alarm: LCD prompts and valve-closing alarms for faults (battery power-off, under voltage, low water, strong magnetic interference).
  • Valve Self-Maintenance: Regular valve rotation removes scale, ensuring flexibility.
  • Water Price Setting: Supports single and stepped water price configuration at the meter end.
  • IC Card Payment: Enables self-service payment via payment terminals.
  • Bluetooth Function (Bluetooth Meters): Connects to mobile Bluetooth for meter setting, reading, and recharge.
