1. The gas meter shows an error and the valve is closed, which should belong to the card smart meter. This kind of gas meter needs to be equipped with a matching battery, buy a certain amount of money, and then insert its valid card into the gas meter. You can display the correct data, return to normal and start the valve.
2. The gas stored in the electricity meter is used up, so just take the card to the gas company to recharge it and plug it in.
Then the battery on the meter is dead. This situation is the most common. Just get a new battery.
4. It is rare that there is a problem with the gas meter, so you can only call the customer service of the gas company to change the meter. The gas company will not repair it, but directly change the meter, and the remaining gas will be transferred to the new meter.
5. The gas meter shows an error, and the reason why the valve is closed is directly related to the fact that the gas meter has no electricity and the gas card has no money. The last one is that if the gas is not used for a long time, the gas meter will automatically turn off. Just press the battery again and the solenoid valve will open.
