Description:

IC card prepaid diaphragm gas meter, based on the valve diaphragm gas meter, integrates contactless radio frequency card technology and combines with the Internet of Things wireless communication module. The gas purchase volume is written into the IC card. After the user swipes the information in the IC card into the gas meter, the gas meter will automatically open the valve to supply gas. During the user's use, the microcomputer in the gas meter automatically deducts the remaining volume. When the purchased gas volume is used up, the gas meter will automatically close the valve to cut off the gas.
