TUBA 1" tubular float level switch

Description

The TUBA 1" float level switch is a small diameter tubular float that has been designed to fit tanks and cisterns having restriced access. Its small 1" diameter allows it to pass through the narrow openings usually found on the side walls of tanks. As the liquid level reaches the float, the mechanical switch inside will tilt, thus closing or opening a circuit connected to an electrical panel. Thanks to its +/-20º switching angle, the TUBA float level switch ensures a very precise level measurement..

Advantages

  • Easy to install, easy to use
  • Installation possible up to a water depth of 55 meters
  • Ecological float switch (no mercury, no lead)

Applications

  • Clear, clean liquids, rain water
  • Slightly aggressive liquids: oils, mud, fuel, paint, etc.
  • Level control of multiple pumps 
  • Emptying / Filling function
  • Overflow or dry-running protection
  • High / low level alarm
