The LIQUID LEVEL CONTROLLER controls liquid level
automatically. Built-in alarms to detect overfill or low level.
Automatic Liquid Level controller…
- 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.
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 floats is fixed at 2.5 inches. So if the depth of the high alarm (F1) is 4 inches for example, then the stop fill float (F2) would be 1.5 inches depth. So when ordering specify F1 and F3. (in the diagram on this page)
Kynar models (LC2-KC) do not have stacked floats but one sensor in each pipe. There is a choice between float switches and capacitance sensors. The capacitance sensors are ideal for dirty liquids that coat or crystallize on float switches
