SOBA SMALL liquids level regulator

Description

The SOBA SMALL is a level regulator equipped with an external adjustable resin 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 SOBA SMALL level regulator ensures a very precise level measurement thanks to its +/-25º switching angle.

Advantages

  • No maintenance needed, thanks to its biconical shape that avoids any clogging. 
  • Easy to install, easy to use
  • Ecological float switch (no mercury, no lead)

Applications

 

  • Clear, clean liquids, rain water
  • Wastewater, sewage water, charged liquids 
  • Slightly aggressive liquids (oils, mud, paint, etc.) and more aggressive ilquids if equipped with a HR HY cable
  • Level control of multiple pumps 
  • Emptying / Filling function
  • Overflow or dry-running protection
  • High / low level alarm
