ATS 165 float level switch for extremely agitated liquids


The ATS 165 is a robust cable float level switch designed for intensive use in extremely agitated and turbulent liquids. Its big switching angle of 165º ensures no jerking of the pump or electrical panels. As a result, the ATS 165 is the ideal solution for level control in tower tanks, for example. This cable float level switch can be connected directly to pumps up to 1.5 HP or through a relay if working with high power pumps.


  • 165º switching angle that protects the pump's engine from jerking
  • 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)



  • Clear, clean liquids, rain water, certain types of wastewater 
  • Slightly aggressive liquids (oil, mud, paint, etc.) and more aggressive liquids if equipped with a HR HY cable
  • Emptying / Filling function
  • Overflow or dry-running protection
  • High / low level alarm
