he industrial flowmeter controller consists of a controller, a flowmeter (optional by users) and a valve, which is used to measure the gas flow in the pipeline, and has the function of prepayment and control.
The user will pay the gas fee to the management department. The management department will write the gas purchasing amount into the IC card. After the user inputs the information in the IC card into the controller, the controller will automatically open the valve to supply gas.
In the user's use process, the micro-computer in the controller automatically checks and reduces the surplus. When the purchased gas is exhausted, the controller will automatically shut off the valve and cut off the gas. The user needs to re-purchase the gas before swiping the card to open the valve for gas supply.
