Atmos® Two-pipe IC Card prepaid diaphragm gas meter IG1.6S | IG2.5S | IG4S
The IGS series are credit gas meters that use encrypted IC cards as data carriers.Our IGS systems are best suited to the needs of natural gas supply companies.Through the IC card to read the gas flow, meter status or abnormal operation of the meter and other information.This allows the operator to obtain relevant data from the customer without on-site reading.
The meter is suitable for all kinds of gas media, such as: household gas, natural gas and methane, etc.Therefore, the scope of application is large, more convenient for users, equivalent to a multi-purpose table, especially affordable and convenient.The integrated calibration system coordinates the movement of the valve with respect to the optimal gas flow.Excellent linear error curves are guaranteed even at low flow rates.Qmin values remain stable and gauges are resistant to contamination due to optimal valve rotation characteristics.
In order to provide users with more assurance, the Atmos® IC Card Prepay Diaphragm Gas Meters meet the requirements of EN1359:1998/A1:2006 and OIML R137-1(2012) standards.
