CG series IC card gas meter

       
 

2 Application
CG series IC card gas meter is a new type electronic gas testing instrument, it is based on J type, C type and G type domestic diaphragm gas meter and the IC card gas meter is formed by fitting with the controller of intelligence IC card gas meter and valve, customer鈥檚 gas consumption and charging is made through the logical encrypted IC card. The charging for gas selling is realized by gas selling computer management system established in the Gas Company. After our concentrating on studies and market application, CG series IC card gas meter controller have been approved by customers, among which, the strong functional JNRQ 03B main plate with the function of testing 鈥渄ead meter鈥 and is widely praised by customer.
