Instruction of Water Level Float
PD series of solar DC pumping controller can work with water level floats for well
and tank. Water level float for well is used for warning of low water level of well,
water level float for tank is used for warning of full water tank.

as the picture showed below. Whether water level float is for well or for tank,
we
