overfill protection system for road tankers that can be used at terminals with modern gantries — or with the most basic filling equipment. It can be seen at the Marichem exhibition in Hamburg, West Germany on October 20-23.
The vehicle-battery-powered system is the latest in the company's Dynacheck range and automatically stops the filling process when completed or if it detects a fault.
It uses optic sensors which are mounted in the top of each tank compartment and connected to the systems control monitor sited near the tank's grouped foot valves.
When switched on the monitor sends out 30 pulses per second and filling continues until the signals are stopped, by the fuel touching a sensor or if a fault develops.
The system is suitable for all light liquids, however hazardous, including LPG. It works independently in each compartment to ensure total filling.
A prototype was shown at TankCon in June.
It is still in the development stage and production is not expected to begin before early next year. It will then become available as original equipment or as a retro-fit through tanker manufacturers.
