Discriminating Liquid Sensor for Interstital Applications


  • Three distinct outputs: dry, water present, fuel present.
  • Compact - Fits interstitial spaces
  • Unaffected by vapors; even at high concentrations.
  • Easy removal and re-installation for cleaning.
  • No moving parts - Long life.

Compact, Side Mount Switches


  • No-leak construction
  • ideal for small tanks
  • Side-wall mounting: internal or external
  • Broad media compatability
  • Operates on falling or rising level
  • Extreme temperature/pressure model
  • Floats can either rise or lower with the liquid level depending on the mounting position

Compact Switches For Higher Temperatures and Pressures


  • Ideal for shallow tanks
  • Broad media compatibility 
  • Selectable to Normally-Open or Normally-Closed by inverting the float 
  • 50 VA SPST switch (standard)

Solid-State, Electro-Optic Secondary Containment Leak Sensor with Fault Detection


  • Solid-state, electronic leak sensor utilizing electro optic technology to detect the presence of liquids in secondary containment applications. 
  • Contains no moving parts
  • Unaffected by vapors
  • Ideal for interstitial spaces

Product Distinguishing Secondary Containment Leak Sensor with Fault Detection


  • Solid state
  • Electronic
  • Utilizes electro-optical and conductivity technologies to detect and differentiate between hydrocarbon-based liquids and water in secondary containment applications. 
  • No moving parts
  • Unaffected by vapors
  • Ideal for interstital spaces

Secondary Containment Leak Sensor w/ Fault Detect Option


  • Provides secondary containment leak detection for above ground and underground storage tank applications
  • Ideal for monitoring shallow liquid levels
  • Available in Buna N or stainless steel float for monitoring in most petrochemical and chemical storage tank applications.
  • Supports Pneumercator's Fault-Detect supervised wiring technology, which automatically detects field wiring faults when connected with a TMS series controller. 

Dual Float Reservoir Sensor


  • Detects level changes within the reservoir 
  • Wired as discriminating or non-discriminating 
  • High alarms for breaches in the inner tank
  • Low alarms for breaches in the outer tank

Level Switches - Single Point
