Level regulator with internal ballast - AQUA MEDIUM


The AQUA MEDIUM is a robust level regulator with internal ballast. As the liquid level reaches the regulator, the mechanical switch inside will tilt, thus closing or opening a circuit connected to an electrical panel. The AQUA MEDIUM is capable of penetrating the thick layers of grease found on waste water pumping stations, and it is the ideal level regulator for limited spaced applications.


  • Robust construction with internal ballast 
  • Easy to install, easy to use
  • Ecological float switch (no mercury, no lead)
