1.Product introduction
The wireless remote water meter is mainly used to measure the total volume of water flowing through the water pipe. The microcomputer in the water meter stores the water consumption automatically. When it detects the meter reading signal, it will send out the data through the wireless frequency band. The user pays water rate and the management department will read in the purchasing information into the database. Then the valve opens to supply water automatically. During the use of water, the smart control system in the water meter will check the remaining amount automatically. When the remaining water is insufficient, the water meter will prompt the alert. After the remaining water is used, it will shut down automatically, and the user needs to repurchase again.
2.Main features
