Product description

The prepayment ladder-charging type water meter is a smart prepayment water meter specially designed for the ladder water price policy carried out over industry of tap water, which takes propeller type water meter as the base, moreover provided with reed switch, low power-consumption electrical control valve, micro-computer control system and smart card information system. It not only changes the traditional water charging method, from “charge follows water” to “water follows charge”, but also realizes the ladder water price charging function. The meter end can store 3 sets of price systems, and final monthly charge is determined by monthly water consumption of users and ladder price settings. The product satisfies all technical requirements in National Standard GB/T778-2007 Measurement on Water Flow in Enclosed Pipelines, Cold Drinking Water and Hot Water Meter and Industrial Standard CJ/T133-2007 IC-card Cold Water Meter.  


  • Accurate metering: Use high-strength material inter-machine which has low starting flow and high metering accuracy.
  • Prepayment function: Water follows charge. The valve automatically shuts down without charge, and automatically starts after charging.
