LEVEL CONTROLLER OVERVIEW

The Level Controller will keep tanks at the right level automatically, either filling or emptying.  In filling mode, when the liquid level drops to the lower float switch, the pump controller turns on your pump to start filling. When the liquid level rises to the high level float, the level controller shuts off the pump. This simple cycle repeats automatically indefinitely to properly maintain your liquid level.

EMERGENCY ALARMS INCLUDED

In addition to the automatic level control, the level controller includes an emergency alarm. As reliable, our controller is, liquid level problems can still happen due to factors not related to the level controller like malfunctioning valves, solenoids, tank leaks, or operator errors. Therefore, to guard against these, there is a float switch reserved just for emergencies. (this makes a total of three float switches altogether) If the liquid level gets too high (or too low can be specified) the “emergency” float produces an alarm with a flashing LED and loud warbling buzzer that is designed to be heard through industrial plant noise. At the same time, the emergency alarm float also provides a redundant relay shutoff.

When an emergency alarm sounds, the audio buzzer can be silenced with a button. The buzzer will stay silenced for 30 minutes, and sound again. (we call this our snooze alarm) The result is that the alarm won’t be forgotten.

EASY INSTALLATION

The pump controller is designed to be quickly installed and working in a few minutes.  After mounting on the tank, the level controller plugs into a standard power outlet.  Since it comes with a piggyback plug, your pump can quickly plug into the receptacle side of the plug.

All our level controllers are easy to switch between pump-up and pump-down operation using a switch inside the enclosure.

DIFFERENT MODELS

The model LC2 on this page has the electronics enclosure mounted on a the pipe with one of the level switchs. If mounting away from the tank is preferred, then the model LC3 has the electronics mounted on a nearby wall. This is especially useful for low headroom situations.

When ordering, the working depths must be specified.  Again, the depths are easy to adjust up or down with a thumbsccrew so it doesn’t need to be accurate to the mm.  And no need to break out bolt-cutters to chop off metal probes!

Polypropylene models (LC2-PF) have a stacked (or double) float. The spacing between the high float and the emergency overflow float is fixed at 2.5 inches. So if the depth of the high level float is 4 inches for example, then the emergency float would be 1.5 inches depth.
