Diaphragm Wireless Remote Control IC card Prepaid
Intelligent Household Gas Meter
Product Introduction
Wireless remote control IC card 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. AMR 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. It 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.
Product Parameters
1. The IC card itself is magnetic proof, of large store capacity, confidential,difficult to counterfeit,hard for scratch,and reliable in performance.
2. It has anti-theft and illegal access resistance function.
3. It has six digits display in LED to show gas consumption volume,money remains,and other data,which is very convenient to the clients.
4. The client’s secret code and communication address can be preset.Once the client’s data has been
set in a gas meter,the IC card can only be used in the gas meter, and cannot be used in other meters. The communication address cannot be changed either.
5. It adopts advance technique and know how,which ensures its accurate measurement.
6. The meter is installed with gas sales device,remote reading device,remote data collector and intelligent
data terminal.It has the merits of collecting meter data outside the house,timely revising unit price,meter valve remote control and efficient monitoring and administration in a modern,automatic way.
7. The meter has two ways in power supply,one being inside battery and the other outside battery.When
the outside battery is off or in low voltage,the meter valve will shut off,but the remote reading device is still under work condition.
8. Wireless transmission rate:9600bps,working frequency 433~470.8MHz.
