The "Static Grounding Monitoring System" functions as a part of an Overfill Protection & Earthing System. These provide a visual green light indicating a confirmed grounding condition of road tanker vehicles during the transfer of flammable and combustible materials. A red light indicates the absence of dependable grounding. An interlock circuit inside the control panel will prevent pumps and equipment from starting until a satisfactory ground is established. The interlock circuit will also shut off pumps and equipment if the ground is lost during the pumping operation.
Overfill sensors are designed to prevent overfill of liquid petroleum products.
Socket and grounding bolt are designed to connect the Overfill Protection & Grounding Systems to the tank truck.
