Discriminating Dispenser Sump Sensor

  • Uses magnetic float switches to detect liquid at two levels.
  • Innovative polymer strip detects hydrocarbons along sensor and floating on water.
  • Compatible with common fuels and chemicals.
  • Detects liquid at 1½" (38 mm) from base.
  • Detects hydrocarbons on sensor and floating on water.
  • Digitally encoded status information sent from microcomputer to ATG from 775+ feet (236 m).
  • Alarms to indicate liquid in sump, hydrocarbon detected, sump is full, and sensor malfunction.
  • Variety of mounting methods possible depending on location. Bracket provided for quick installation.

No matter what the monitoring application is, Franklin Fueling Systems offers a sensor solution tailored to the specific requirements of each application.
