IC card diaphragm gas meter
Product overview
The IC card diaphragm gas meter is an integrated intelligent gas meter with IC card for prepayment and automatic charging of gas meter.
The product has dual synchronous display of mechanical counter and electronic counter with the advantages of beautiful shape, accurate measurement, clear and convenient reading, easy to use, and so on. IC card adopts logical encryption to ensure information security. Gas meter sale management system can store all initial file information of the user gas meters as needed, such as the gas meter factory No., constant, user address, which could solve the problems of household meter reading and charge difficulty in gas company in order to improve the management level and work efficiency. It is an ideal measuring instrument to meet the needs of modern gas management.
