  • Highlights

    • Installs in the interstitial space of steel and fiberglass double wall tanks and sumps.
    • Uses light beam traveling through probe to determine if sensor is wet.
    • Microprocessor inside sensor interprets readings and communicates data to the EVO™ Series fuel management system.
    • Fail-safe digital communications with built-in alarm if sensor malfunctions.
    • Sensor can distinguish between petroleum and water.
    • Alarms indicate petroleum present, water present and sensor malfunction.
  • Specs


    • UL listed.
    • ATEX approved.
    • IECEx approved.


    For dry tank interstitial monitoring.


    Each DIS comes with 25' 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.
