Wireless dry valve controlled water meter
LXSGF-15GW~25GW wireless valve controlled cold water meter, based on accurate measurement, realizes water measurement data collection, information remote transmission and interaction, and valve opening and closing functions. It uses wireless communication, does not require wiring, and is convenient for construction and installation, making it very suitable for modern property management needs.
The counting mechanism of the mechanical metrology part is vacuum sealed, and the dial wheel is not affected by water quality. The readings are permanently clear, and the dial wheel displays a large range and high accuracy of the count value. The messaging module and the base meter adopt a separate structure, and the power supply battery is independently packaged for easy battery replacement.
