HORIZONTAL FLOAT
SWITCH SENSOR (HFS)
The HFS is designed for liquid detection in dry fiberglass tank
interstitial spaces. These 2-wire, non-discriminating liquid
sensors are used with all EVO™ Series Automatic Tank
Gauges (ATGs).
HIGHLIGHTS
SPECIFICATIONS
• Fiberglass interstitial monitoring using a 2-wire sensor.
Applications
• For dry fiberglass tank interstitial monitoring.
For dry tank interstitial monitoring.
• Highly reliable magnetic-float/reed-switch technology.
• Chemical-resistant materials.
ORDERING INFORMATION
• Rounded design makes it easy to remove for cleaning and
reinstall after an alarm condition has been triggered or for
maintenance and testing.

Description
FMP-HFS2
Horizontal float switch sensor (all EVO™ Series ATGs)
TSP-KI2
Interstitial sensor riser cap kit for 2" riser pipes
• 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.
TSP-KW4
Interstitial sensor riser cap kit for 4" riser pipes
FUEL MANAGEMENT
SYSTEMS
• Easily fits tight interstitial spaces.
Note: The FMP-HFS2 wires to the 2 wire sensor module or the 3 wire sensor
module. It cannot be wired to the probe module.
DISCRIMINATING INTERSTITIAL
SENSOR (DIS)
The DIS installs in the interstitial space of steel and fiberglass double wall
tanks and sumps and detects the presence of various liquids in tanks as well
as sumps and other locations.
HIGHLIGHTS
SPECIFICATIONS
• Uses light beam traveling through probe to determine
if sensor is wet.
Applications
• Microprocessor inside sensor interprets readings and
communicates data to the EVO™ Series ATG.
• Fail-safe digital communications with built-in alarm if
sensor malfunctions.
• Alarms indicate petroleum present, water present, and
sensor malfunction.
• Each DIS comes with 25' (7.6 m) of oil-resistant cable. For
fiberglass tanks, the DIS is pulled into the interstitial space
using a "fish" string or wire. For steel interstitial tanks, the
DIS is lowered directly to the bottom of the interstitial space
through a 2" NPT fitting provided for that purpose on the
tank. Optional installation kits are available which include a
riser cap and other parts required to complete installation.
For dry tank interstitial monitoring.
