LXSF-15Z~25Z无线光电水表

1.Product introduction

The wireless remote photoelectric water meter is mainly used to measure the total volume of water flowing through the water pipe, which is widely used in the family, apartments, commercial buildings and other occasions where tap water is charged per household. This type of meter adopts the principle of optoelectronics to encode the encoding disk, to make the reading more direct and accurate. The microcomputer in the water meter stores the water consumption automatically. When it detects the meter reading signal, it will send or receive the data through the wireless frequency. The user pay water rates 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 "intelligent control system" 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.
