Overview: LXSGY-15E-25E/S dry dial wireless remote valve control water meter This series of water meter applies low power consumption remote reading system, signal transmitted through public wireless channel or exclusive wireless channel of tap water companies. Integrated structure of meter body and valve; remote control of valves on water meters; long distance shut down in the event of purposely arrearage; water supply thus will be cut off as a warning to get back payment. This measuring accuracy can reach grade B of GN/T778-1996 standard.
