The Overfill Prevention Sensor GWG

The filling sensor is a safety mechanism to prevent overfilling of storage and bunker tanks when they are filled with gasoline, diesel, and fuel oil from road tankers. It consists of a level sensor inside the tank and a amplifier with valve inside the road tanker. The QSS/ASS plugs are part of a safety system that prevents the blending of products due to a faulty connection and that checks the hose connection to the road tanker during the filling process.

Coded Electrical Plug Connection Type FP 903/907 ASS K for QSS and ASS

The product regognition QSS is a device to prevent the mixing of fuels or other liquids during the filling of a storage or bunker tank from a road tanker. The filling hose safety device ASS monitors the correct connection of the filling hose to such tanks. The FAFNIR QSS/ ASS solutions consist of a plug on the tank and a coupling on the road tanker. The release signal for the filling process is performed by an amplifier in the road tanker that recognizes the correct pairing and functioning of the coupling connection. By the way, the overfill prevention sensor for filling stations is integrated into the overfill protection system via this coupling connection.

The Overfill Prevention Sensor Testing Device ME 6

Overfill prevention sensors must be checked on a regular basis. This is usually performed during a tank inspection. An optimal and safe check of overfill prevention sensors is guaranteed by the overfill prevention sensor testing device ME 6.
