The LIQUID LEVEL CONTROLLER automatically controls liquid level. Built-in alarms to detect overfill or low level. 


Automatic Tank Level control…

  • Rugged. Built for rough, wet and corrosive environments. NEMA 4X rating.


  • Reliable. Floats are protected inside a pipe and completely screened in.

  • Adjustable depth. Both float switches can be adjusted with no tools.


  • Independently adjustable float depths.

  • Easy installation with a piggyback plug. Just plug in your pump up to 15A.


  • Versatile. Switch between pump-down or pump-up operation.

  • Emergency level alarms for high and low level with Loud 103dB buzzer.  Warbling tone cuts through the loudest industrial noise.

The LC2 Level Controller will automatically cycle your pump to keep your tank filled, or empty as needed.  In tank-filling mode, when the liquid level drops to the bottom float switch, the LC2 Pump Controller turns on your pump to fill the tank. When the liquid level rises to the high level float, the LC2 shuts off your pump. The cycle repeats automatically as needed to properly maintain your liquid level.

To switch between pump-down or pump-up mode, simply remove a circuit board jumper.


If there is a problem that causes the liquid level to rise above the high level-control float, or fall below the low-control float, extra “emergency” floats produce an alarm. (so there are a total of 4 float switches altogether)  These emergency alarms produce a flashing LED and loud warbling buzzer that can be heard through industrial plant noise. The emergency alarm floats are also a redundant relay shutoff.

The audio buzzer has a silence button with a 30 minute snooze alarm standard so the alarm won’t be forgotten.


The Pump Controller is designed to be quickly installed and working in a few minutes with no tools. Simply mount it on your tank and plug it in.  The depths of the floats are adjusted with thumbscrews.  The standard high level pipe is 8 inches long. 

To connect your pump or solenoid, it comes with a convenient piggyback plug so you can simply plug in your pump directly.  Alternatively we can supply a solenoid valve wired to the Level Controller as an option. 


The LC2 on this page has the electronics mounted on a pipe near the tank.  The LC3 performs the same function but has the electronics mounted in a wall box.  LC3 page here 

The low level float pipe can be 10 inch, 20, 30″ etc.  Each of the pipes is adjustable for most its entire length.  For example, a 20 inch long low float pipe can be adjusted from 5-20 inches working depth

Polypropylene models (LC2-PP) have double (stacked) polypropylene floats so each control float has the emergency float 1 inch away.

Kynar models (LC2-KK) do not have stacked floats but rather an individual (Kynar) float switch in each PVDF pipe.  Therefore each pipe length can be specified separately.  The upper float switch depth is assumed to be 8″ unless otherwise specified.
