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.

Working conditions

a. Qsthe maximum flow allowed without any damage in short period;
b. Qpthe appropriate flow used on normal conditions
c. Qt---the flow emerging when the flow range is divided into two zones
d. Qmin---the minimum flow can be indicated on meter within the max. permissible error
