Description
DOL Duplex Pump Control Panel(L932-S)
Eliminates the need for at least 5 water level sensor or 3 float switches: stop-level, normal- level for one pump, high-level for two pumps, overflow-alarm level. overflow-alarm level. Thus significant cost-savings result from dramatically reduced purchasing and clearing of sensors or float switch
More secure because it uses level transmitter, whereas sensors or float switch often fail because of the effect of sludge.
Different water levels (depth) for starting or stop the pumps can be set via LCD screen directly and real time depth value displaying;
