Pipeline premium drinking water meter
The LYHF-15BW wireless valve controlled purified water and cold water meter, based on precise measurement, realizes water measurement data collection, remote information transmission and interaction, and valve opening and closing functions. It uses wireless communication without wiring, making it convenient for construction and installation, and is very suitable for modern property management needs.
The counter structure of the mechanical measuring part is a dry structure, the counting mechanism is vacuum sealed, the dial wheel is not affected by water quality, and the reading is permanently clear. The character wheel displays high accuracy in counting values.
