Overfilling protection in road tanker vehicles with level gauge adjustable to filling amount integrated in each tank chamber which with overfilling of chamber interrupts filling operation

摘要

The protection system includes at least one switch in the form of a Reed contact (13) or proximity switch, arranged in a flange housing (15). The switch works in conjunction with a magnet (12) of a float (11), depending on the filling amount and the float buoyancy for shutting off the closing organ at the refinery or the filling station. An electronic circuit (EL) is provided for monitoring the Reed contact or the proximity switch and identifies disturbances in the electric system of the tanker vehicle filling section, and with disturbances or overfilling switches off the filling system at the refinery or the filling station.
