LEVEL CONTROLLER OVERVIEW

The Level Controller will keep tanks at the right level automatically, either filling or emptying.  In tank-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 emergency alarms. As reliable, our controller is, liquid level problems can still happen due to malfunctioning valves, solenoids, tank leaks, or operator errors. Therefore, to guard against spills or empty tanks, there are two floats reserved just for emergencies. (this makes a total of four float switches altogether) If the liquid level gets too high or too low, these “emergency” floats produce 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 floats also provide a redundant relay shutoff.

When an emergency alarm sounds, the audio buzzer has a silence button with a 30 minute snooze alarm, so the alarm won’t be forgotten.

EASY INSTALLATION

The pump controller is designed to be quickly installed and working in a few minutes with no tools.  After mounting, the level controller plugs into a standard power outlet.  Since it comes with a 120V piggyback plug, your pump can quickly plug into it. The output available is 15A @120V.

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 polypropylene pipe and is designed to be mounted at the tank. If mounting away from the tank is preferred then the model LC3 mounts on a nearby wall.

The standard depth we use for the high level pipe is 8 inches working depth. This depth can be easily adjusted as short as 2 inches just by loosening the thumbscrews.  This is good for most installation. The depth of the low level pipe comes in increments of 10 inches. Again, the depth is easy to adjust up or down.  No need to break out bolt-cutters to chop off metal probes!

Polypropylene models (LC2-PP) have stacked floats. The spacing between floats is 1 inch.

Kynar models (LC2-KC) do not have stacked floats but instead use a capacitance sensors.  These are ideal for dirty liquids that coat or crystallize on float switches. For more info please see our page on capacitance level controllers.
