Abstract:
1. A device for determining and/or monitoring the fill level of a fill material in a container, comprising: a transmitting-/receiving-unit, which produces and receives high frequency, broad band measurement signals; an evaluation-/control-unit, which determines the fill level of the fill material in the container on the basis of the travel time of the high frequency measurement signals reflected at the surface of the fill material in the container; a conductive element, on which the high frequency measurement signals and the reflected measurement signals are guided; a coupling unit, which couples the measurement signals onto said conductive element and the reflected measurement signals into said transmitting-/receiving-unit; an attachment part, with which said device is secured above the maximum fill level to be measured and/or monitored; and a horn-shaped element in the upper region of said conductive element, said horn-shaped element defining a lower open area, and is arranged such that its lower opening area faces in the direction of the surface of the fill material and lies approximately in the plane of said attachment part.
