ST-15 Single Point Overfill Prevention Controller

Brand: Scully Signal Company
The Scully single point overfill prevention controllers feature two-wire optic or thermistor sensing. They are mounted at a loading rack or fill station for connection to a single compartment tank vehicle. 

The ST-15 provides the vehicle with an adequate static ground path to the rack provided the vehicle overfill equipment is wired and maintained to factory specifications. 

For additional ground proving options, the system works in conjunction with the Scully Groundhog Self-Proving Ground Verification System.
Features
  • Maximum safety with Dynacheck® automatic and continuous self-checking circuitry
  • Will not permit loading under any fault or wet sensor conditions
  • Signals for automatic shut-off of product flow within a half-second of detecting an overfill condition
  • Ideal overfill prevention for refuelers, rail tank cars, tank trucks, chemical trailers and other one compartment vehicles
  • 30 years of proven, dependable performance
  • Easy connection to vehicles with versatile high impact plug and cable units
  • Approved by Factory Mutual
