Description


The contactless IC card gas meter with prepayment function is fitted with IC card and valve control switch and other functional modules to complete the gas consumption reading and settlement. The meter accumulates the gas consumption purchased by the users, monitors and records the gas for use process, as well as conducts terminal settlement; the prepaid gas meter also automatically manages the valve according to the remaining gas consumption and its operating status; the gas company's charging and user payment needs could be satisfied through the prepayment management system, independent payment terminal and Bluetooth card reader.
