Overfill & Grounding

The most advanced terminal overfill prevention and ground verification system available.

  • The only control system that offers overfill prevention, static grounding, and vehicle identification all-in-one unit
  • The ultimate in terminal loading safety with a patented design that continuously monitors the relay contacts—for petroleum and chemical loading racks
  • Incorporates Dynacheck® Dynamic Self Checking® circuitry for overfill prevention, ensuring that every critical component is automatically and continuously checked for maximum loading safety
    • This includes the control unit, wiring, and sensor circuitry, and should a fault be detected, it signals a loading shutdown to prevent product from overfilling
  • Over 15 years of proven performance in the field—the number one choice worldwide

Overfill Prevention Controller

Multiple-Point, Optic-Sensing Overfill Prevention Control Unit

  • Interfaces with five-wire optic sensors
  • Used, typically for bottom and top-loading of tank vehicles
  • Mounted at the loading rack/gantry and connects to the vehicle via the Scully plug and cable assembly (sold separately).
  • Features Dynacheck® circuitry for automatic and continuous self-checking of all system components
  • For vehicle ground/earth verification options, consult Scully for information on the Groundhog Self-Proving Grounding System.

Static Grounding

Vehicle Static Ground Verification System

  • Self-proving technology based on Scully’s original patented design
  • Can operate in conjunction with your Scully Overfill Prevention System (ST-35® or ST-15) or as an independent ground verification unit
  • Immediately shuts down the loading operation if proper static grounding is not detected

Tank Overfill Prevention

Safe, reliable, high- and low-level warning and spill prevention system for storage tanks

  • The system incorporates Dynamic Self-Checking® circuitry which monitors the controller, wiring, connections, and sensors for faults 30 times per second for maximum safety
  • Sounds an audible alarm and/or controls pumps and valves for automatic shutdown when the sensors detect liquid or a fault in the system
  • As a high level warning and emergency shut-down system, it operates independently from your gauging system to ensure that inventory inaccuracies do not compromise the safety of your operation.
  • The sensors wired to a control unit provide high level detection for a wide variety of petroleum and chemical products
