HFS

Horizontal Float Switch

The HFS is a 2-wire, non-discriminating liquid sensor designed for liquid detection in dry fiberglass tank interstitial spaces.

Horizontal Float Switch Sensor

Fiberglass interstitial monitoring using a 2-wire sensor.
For dry fiberglass tank interstitial monitoring.
Highly reliable magnetic-float/reed-switch technology.
Chemical-resistant materials.
Easily fits tight interstitial spaces.
Rounded design makes it easy to remove for cleaning and reinstall after an alarm condition has been triggered or for maintenance and testing.
Each HFS comes with a 25’ (7.6 m) oil-resistant cable.
For fiberglass tanks, the 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.
