Contact IC Card Diaphragm Gas Meter
Description
The contact IC card smart gas meter with prepayment function is equipped with functional modules such as IC card and valve control switch to complete the gas volume reading and settlement. The meter accumulates the gas volume purchased by the users, monitors and records the gas use process, as well as conducts terminal settlement; the prepaid gas meter also automatically manages the valve according to the remaining gas volume and its operating status; Through the prepayment management system, independent payment terminal and Bluetooth card reader, the gas company's charging and user payment needs could be satisfied.
