Type-compatible overfill prevention device FST3.1V 5522014

Gas withdrawal valve for LPG tanks with safety device tp prevent overfilling.
Operating principle of the overfill prevention device:
If, during the filling process, the limit indicator is connected to the controller of the overfill prevention device on the tank truck via a cable by means of a plug with shrouded conntact. When reaching the allowed filling limit, this sensor dips into the LPG liquified under pressure and, caused by cooling, changes its electrical resistance. This change in resistance leads to the immediate stop of the filling process via the controller.
