<p>The device has a tank connecting piece (2) arranged over a tank opening (33). A filling piece (3) is connected with the tank connecting piece. A pipeline hose and sensor elements are arranged at the filling piece. A filling level sensor (4) e.g. reflection sensor, and pressure sensors are provided as the sensor elements. A bolting unit (31) is designed as a mechanical locking unit and/or acoustic and/or optical warning unit. A ring sealing element is inserted into a ring recess. The filling level sensor is selected from one of a group consisting of a light guiding sensor, positive temperature coefficient (PTC) sensor, negative temperature coefficient (NTC) sensor, capacitive sensor, hall sensor, inductive sensor and a potentiometric sensor.</p> |
