Industrial liquid level controllers are used to monitor constant level, high or low level, and leak detection types of sensing. Additional features may include adjustable sensitivity, built-in timers, LED indication, filter alerts, and auto shut off valves. Solid state or mechanical contacts are actuated upon detection with contact form variations of DPDT, DPST, SPDT, and SPST functionality.
