ABSTRACT:
A level sensor which is capable of largely eliminating the influence of structural parts and/or the formation of deposits on the measuring accuracy and on the measuring sensitivity of the level sensor. There is provided, a launching unit which has at least one length, which essentially corresponds to the distance from the container wall to the lower edge of the structural part, and which is positioned in such a manner that a transition area launching unit conductive element is located approximately in the plane of the lower edge of the structural part, with the diameter of the opening of the launching unit on the transition launching unit conductive element is in the order of magnitude of the wavelength of the high-frequency measurement signals.
