Liquid Level Control
Model type 31X shown

The 31x series are conduction/resistance sensing type liquid level controllers. Pump-up operation begins when power is applied. With an empty tank, the control relay is energized until liquid contacts the high probe. As the tank is emptied and the liquid goes below the low probe the relay again is energized and the cycle is repeated. Pump-down operation is similar, with the control relay being energized upon liquid contacting the high probe. The relay is de-energized upon liquid contacting the high probe. The relay is de-energized when liquid falls below the low probe.

Selection options
