How to calculate the balance of gas meter?

natural gas meters are divided into IC card meters, household appearance meters and remote transmission meters. The accounting method of the balance is as follows:

1. IC card table: After purchasing natural gas, insert the IC card chip upwards and store the electricity on the card in the meter. Insert the IC card chip downward, and the screen value will jump three times, showing residual gas, recharge gas and accumulated gas. The top shows how many cubic meters of gas are used, and the bottom shows the balance.

2. Home appearance: the natural gas meter is installed outdoors. After inserting the card, the value on the screen will jump three times, showing the remaining gas volume, recharge gas volume and accumulated gas volume respectively.

3. Remote transmission electricity meter: Press the red button of natural gas electricity meter to display the unit price, balance and gas accumulation. You can only check the natural gas usage according to the values in the black box. If the fee is overdue, you will receive a text message.
