2 Wire Optic Sensor

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
