Sapphire wireless remote control IC card electronic gas meter is the high-tech measuring meter of a new generation which accords with standards of GB/T6968-2011<diaphragm meter>, CJ/T112-2008<IC card diaphragm gas meter>and JG/T162-2009<residence remote data transmission system>.
It can thoroughly change the traditional payment model of low data reading efficiency, errors, long cash withdrawal cycle and labor costing. Electronic gas meter is a pre-paid meter with IC card as a media. It possesses varieties of functions of accurate measurement, reliable performance, simple operation, convenient maintenance and exclusive matching set with one card-one meter.
Through low energy consuming wireless communication technology this meter can automatically read and monitor meters’ data. Electronic gas meter also has high cost performance and especially suitable for household gas measurement. It is one of the best gas measuring instruments for modernized gas management.
