Measuring arrangement for fuel tank

摘要

The arrangement is formed of an insert, which is inserted into a fuel inlet of the tank. The insert comprises a casing (4), which forms a first space (4') through which a filling of the tank is possible, and a measuring cylinder (9), which forms a measuring chamber (12) limited by a measuring butt (10). The measuring butt is moved by increase of the volume of the measuring chamber against at least one feather element (11) from a starting position. At least one steered ventilation opening (14) is provided in the casing, through which the air and/or gas volume displaced by filling the tank is led away. The ventilation opening is increasingly opened with the movement of the measuring butt (10) from the starting position.
