Product use
The LXSY series IC card remote water meter is a new generation of prepaid remote water meters designed, developed, and produced in accordance with the technical requirements of CJ/T133-2012 Chinese urban construction industry standard "IC card cold water meter" and Chinese national standard GB/T778-2007 "drinking cold water meter and hot water meter".
Product features
1. IC card remote water meter adds remote management function on the basis of IC card intelligent water meter. Through the remote module, the management party can collect the used water and remaining water of the user's water meter at any time. At the same time, the management party can also obtain the working status of the water meter remotely, and can promptly come to the door for maintenance when the water meter malfunctions. The management can also remotely control the opening and closing of the water meter valve through the remote transmission function.
2. The base meter adopts four pointers and five character wheels, which are clear and easy to read. The valve adopts a suspended structure, with small switching torque, long service life, and reliability. The meter and valve are integrated, and the structure is reasonable.
