Adopting a prepaid management mode, users can use the gas after opening an account and purchasing it, and the meter will automatically close the valve after use;

Use logical encryption IC cards, one card per meter, to completely prevent counterfeit cards.

Equipped with automatic gas shortage alarm function, reminding users to purchase water in a timely manner.

It has a complete automatic detection function and can notify users of low battery voltage, air valve switch and other information through display and sound.

The user card automatically sends back various information about the user's gas usage.

Adopting dual measurement of mechanical and electronic.

One household, one card, completes the data information exchange between the gas meter and the upper system, and can be combined with our company's IC card prepaid products to form the "IC card water, electricity, heat and gas one card" system
