OVERFILL PREVENTION

TIMM’S OVERFILL PREVENTION CONTROLLER EUS-2

Optimum safety for bottom loading tank trucks

The bottom loading of road tank trucks at oil terminals and refineries is characterised by the simultaneous loading of fluids into closed tanker compartments with high loading rates and no manual supervision.

To prevent hazardous spills, the accumulation of electrostatic charges and the evaporation of emissions, an emergency shut-off system, supervised grounding and vapour collection is mandatory by law to ensure safe loading processes.

Functional Principle:

The Overfill Prevention Controller EUS-2 is the central component of the overfill prevention system according to European VOC Directive 94/63/EC and American API RP 1004.

EUS-2 monitors the level sensors at the tanker compartments, the truck grounding and the vapour recovery connection. If a critical situation is detected, the filling process is interrupted immediately at the loading gantry. The controller is able to detect the type of truck installation and automatically activates the required operating mode.

Application Areas:

The EUS-2 controller is installed at the loading gantry and connected via its control outputs to the control system or loading computer. It is compatible with all trucks with optical or NTC thermistor high level sensors compliant with EN 13922 (five-wire and two-wire).

The sensors are mounted firmly to the truck’s tank compartments and wired to a standard connecting socket. Products to load are for instance gasoline, diesel, jet fuel or ethanol (gas group IIB).
