IC-Card Prepaid Diaphragm Gas Meter

Two-pipe IC-Card diaphragm gas meter IG1.6S | IG2.5S | IG4S

IC-Card diaphragm gas meter is a kind of credit gas meters and it can use an encrypted IC card as a data carrier. Our IGS system is designed to optimally adapt to the needs of gas supply companies. The IC-card can read various information such as gas flow, meter status or unusual operating conditions of the meter. That enable the operator to get relevant data from the customer without on-site reading. This IC-Card gas meter can be used for natural gas, town gas, biogas, liquid gas, methane gas.

The integrated calibration system plays a major role in coordinating the optimum gas flow. Even at low flow rates, the gas meter still can do a excellent job with accurate measurement. Even at a low flow rates the extraordinary performance of error curve is guaranteed. This gas meter is resistant to contamination with stability of Qmin value thanks to the optimum sliding characteristics of the valves.

Our IC-Card prepaid diaphragm gas meter comply with requirements of the EN1359:1998/ A1:2006 and OIML R137-1 (2012).
