Horizontal Float Switch Sensor (HFS)

Horizontal Float Switch

The HFS sensor is designed for liquid detection in dry fiberglass tank interstitial spaces. These 2-wire, non-discriminating liquid sensors may be used with EVO™ 550 and EVO 500™ Automatic Tank Gauges (ATGs) as well as the S940 alarm console.

  • Fiberglass interstitial monitoring using a 2-wire sensor.
  • For dry fiberglass tank interstitial monitoring.
  • Highly reliable magnetic-float/reed-switch technology.
  • Chemical-resistant materials.

Installation

Each HFS comes with 25' of oil-resistant cable. For fiberglass tanks, the HFS sensor is pulled into the interstitial space using a “fish” string wire. Optional installation kits are available which include a riser cap and other parts required to complete the installation.
