SCUL-SENSETM Two-Wire Optic Sensor

Liquid Level Sensor for Tank Trailer Overfill Prevention

  • System-wide “closed loop” Dynacheck® pulsing signal ensures safe and reliable loading operation
  • Purpose-built for liquid petroleum product overfill prevention and point level detection
  • Designed to be used with the Scully Intellitrol® and ST-15 series loading rack control monitors
  • Can also be used with the Scully IntelliCheck®3 and IntelliCheck2® Control Unit

  • Requires no warm-up time, so no waiting for permit light
  • Overfill prevention applications include road tankers, rail cars, and storage tanks
  • Eliminates operator involvement to end the loading operation—controlling pumps and valves are shutdown if rising fuel contacts the sensor
