The principle of a remote water meter is:

The data of the on-site measuring instrument and transmitter are transmitted to the monitoring and reading center through GPRS wireless communication, and the data are summarized and analyzed in the monitoring and reading center to provide a basis for management and charging.

The power supply of data transmission is the built-in battery, and the removal will not send a signal, but the control center will not receive the signal and will pop up a prompt, and the personnel who exceed the standard will definitely have to check it, and they will install a battery on you again.

Nowadays, many water meters have the function of power-off and shut-off valves, and it is estimated that they will not be used if the battery is removed.

After the smart water meter removes the battery, the LCD screen does not display, and the built-in water valve automatically closes and does not produce water.

If you dismantle it, you can't bill, of course you can't use it.

The battery is to drive the LCD screen and the electric valve, you dismantle the battery and the mechanical part is walking, so it does not affect, but after a long time, someone will check, and you have to pay the water bill.

I unplugged the water meter at home, and it's still spinning, what's going on.

Basically, it is difficult to repair, like the plug-in card water meter has been eliminated. There's no place to fix this professionally. For the water company, they will directly replace you with a new one, and they will not bother to repair it for you.

The prepaid water meter you use does not have the function of shutting off the valve when the power is off, if there is a power-off valve shut-off function, take out the battery, and the water meter will automatically close to prevent water theft.

Pay the money first and then use the water The user will hand over the water bill to the management department, the management department will write the amount of water purchased into the IC card, the user will enter the information in the IC card into the water meter, the water meter will automatically open the valve to supply water, in the process of user water, the microcomputer in the water meter will automatically reduce the remaining amount, after the purchased water is exhausted, the water meter will automatically close the valve and cut off the water, and the user needs to re-purchase the water after swiping the card to open.

Prepaid water meters.

There is no water, there is no electricity, the smart water meter system senses the low voltage and sends a command to close the solenoid valve, and there will naturally be no water, otherwise how to call a smart water meter?

No, it will automatically turn off when the power runs out.

If you remove the battery, it won't run.

Don't think about it, you can't steal it.

There's nothing wrong with that, just like the phone's memory, it uses disconnected memory.

No problem. Basic functions. However, don't leave the battery in the table for too long to prevent leakage after a long time and affect the use.

It must be able to, and those who don't sell water don't die.

It is caused by the power supply exceeding its shelf life and not enough power. A new battery is required.

Here's how to change the battery:

1. Find the water meter model, the original battery and the illustration model.

2. There is a round cover on the water meter, which needs to be pried out along the edge with a blade, and after opening, it is a large Phillips screw, and the battery can be seen when opened with a slotted screwdriver.

3. There are round covers on both sides of the meter, and one side is convenient to take out the battery and plug wire, take out the battery, unplug the plug, replace it with a new battery, and then insert the card to see if it can be read normally.

4. If you can't read it, unplug the battery, install it and try it a few more times, first confirm the plug interface of your own water meter, and then go to buy it online.

There may be dealers who sell lithium batteries for smart water meters do not understand the characteristics of this special lithium battery, and the lithium battery is not activated before delivery, and the user still shows that the battery voltage is low after installing the battery, and the user repeatedly plugs and unplugs the water card more than 6 times, and it should not show the prompt of low voltage.

Reasons for lack of electricity:

The power supply has passed its expiration date and the power is not enough.

Battery voltage can be measured with a multimeter:
