Application
The Scully Five-Wire Optic Overfill Prevention Sensor(s) employs optic technology to detect the presence
of liquid in a tank or vehicle compartment. The sensor is wired to a Scully Socket, mounted on the
vehicle (tanker) chassis. Connecting a plug (and cable) to the socket connects these sensors to a Scully
Overfill Prevention Controller located at a rack.
The Scully SP-FU Overfill Prevention Sensor is available in two different holders for tank mounting. The
holder(s) provide space for wiring connections inside the holder. Model SP-FU/MHC is a Five-Wire optic
sensor with a 2” NPT threaded holder. Model SP-FU/MHCF is the sensor with a flanged style holder.
This sensor assembly is designed to sense liquid product when it is near the top of a tank trailer
compartment. It is intended to be used either:
1.As part of the Scully IntelliCheck® Overfill & Retained Product Monitoring System
2.As a stand-alone overfill prevention sensor in conjunction with the appropriate Scully overfill prevention
control monitor mounted at the loading rack or fill stand.
3.Scully Load Anywhere
When properly installed in a tank trailer compartment, at a point just above the compartment's normal fill
capacity (marker), the SP-FU Overfill Prevention Sensor will sense an impending overfill condition and
signal for immediate shutdown of product flow.
Sensor Outline Drawing
Standard sensor shaft length of 7-inches with standard 2 1/8-inch high holder cover provides for sensing
level adjustability as shown. Longer shaft lengths and a 1 3/8 inch high holder cover are also available to
accommodate most tank trailer mounting configurations (consult factory for details).
