IC card gas meter
PRODUCT APPLICATION
IC card diaphragm gas meter is built by assembling the main controller, built-in motor valve and the measuring sensor etc. on the base meter. Being the information carrier, Iccard is used to pass the information and link IC card diaphragm gas meter installed in family with IC prepayment gas meter sales management system in Gas Meter Co., this will realize prepayment managing.
