L-5SS Liquid Level Switches

Description

Specific Gravity Compensating

  • Featuring continuously adjustable float buoyancy control to allow use in fluids with specific gravity down to 0.6
  • Continuous buoyancy control allows switch activation at oil/water interface
  • Consult factory for other bicomponent fluid interface systems.

Wetted surfaces

302, 316 stainless steel, Viton elastomer seal, and Teflon gasket allow operation in a wide spectrum of environments such as:

  • Contaminated ground water
