Abstract: The invention relates to a filling level measuring device which is used to measure the level of a filling material in a container (1) and a probe (17) is provided, which protrudes inside said container. The filling level measuring device can be mounted and dismounted without the probe (17) needing to be moved in the container (1).

Abstract: The invention relates to a level sensor (1). The aim of the invention is to provide a level sensor (1) which is capable of largely eliminating the influence of the structural parts (4) and/or of the formation of deposits on the measuring accuracy and on the measuring sensitivity of the level sensor (1). To this end, the invention provides, among other things, that the launching unit (2) has at least one length, which essentially corresponds to the distance from the container wall (3) to the lower edge (5) of the structural part (4) and which is positioned in such a manner that the transition area launching unit conductive element is located approximately in the plane of the lower edge (5) of the structural part (4), and that the diameter of the opening (8) of the launching unit (2) on the transition launching unit conductive element (6) is in the order of magnitude of the wavelength of the high-frequency measurement signals.

Abstract: The invention relates to a measuring device (1) which determines the filling level by means of high-frequency measuring signals which are guided along a waveguide (5).
