Highly secured with logic encryption card and CPU card
Legible LCD display
High measurement accuracy
No magnetic interference with over-current protection
Description
The 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 user, monitors and records the gas use process, as well as conducts terminal settlement. It 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 utility's charging and user payment needs could be satisfied.
Features
Highly secured with logic encryption card and CPU card.
Rapid arithmetic speed and low power consumption with 16 digit RISC mixed signal processor.
Legible LCD display.
Protects against various malicious attacks in real-time recording and the valve is automatically closed. Simultaneously, the gas consumption information will be transmitted to the gas sales management system via the IC card.
Data download of accumulated gas consumption and various abnormal error logs.
Real time monitoring of basic gas meter
Optional real time clock. The gas consumption can be controlled and managed within time-interval and the user’s actual gas consumption can be counted by time periods
Prepayment functionality
Gas anti-stealing
High measurement accuracy
Excellent card compatibility and system integration
Autonomous valve shut off due to zero gas consumption, loss of power, deadlock and under-voltage
No magnetic interference with over-current protection
