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.
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.
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).
