Our water meters have an automatic valve closing feature so that the supplier can open/close the valve through the main system.In some areas, clean water resources are scarce, and the economic status of the residents is not high.In some places, people in the same area use the same water, which can easily lead to disputes.People living closer to a water source are perceived to be using more, leading to disputes.And this situation will lead to people are not willing to pay the water fee, and then pay the water meter can not automatically close the valve, only through manual to manual valve, special trouble.And our product has the function of remote control on/off valve. Once the resident's payment relative to the water source is used up, the system will remotely control the automatic closing valve.Only when you recharge and enter the Tokens can you reopen the valve and use the water.In this way, residents' arrears in fees are solved, and the annual fees charged by suppliers can be basically collected without too much loss, namely water loss.
