详细介绍

 

1.Product introduction

The wired remote water meter is mainly used to measure the total volume of water flowing through the water pipe. The principle is adding remote module to the smart IC card water meter to achieve remote control function. The meter can be used as both prepaid IC card meter and remote meter. The user pay water fees and the management department will read in the purchasing amount of water in the database, and then the water meter will supply water automatically. During the use of water, the "remote meter reading software" installed at the management center will reduce the remaining amount automatically. When the remaining amount is insufficient, the meter will prompt the purchase of water. After the remaining water is used, it will shut down automatically, and the user needs to repurchase again.
