Patent attributes
The invention relates to a level meter for metering the level of a filling substance in a container by means of electromagnetic signals that are guided into and out of the container along a waveguide. The inventive level meter guarantees a high tightness even at large temperature variations at the point of measurement or under great pressure or tensile forces acting upon the waveguide. The inventive level meter comprises at least one waveguide that projects into the container, guides the signals into the container and guides the signals reflected by the surface of the filing substance out of the container and is fixed in a housing mounted on the container. An elastic molded element that is clamped parallel to a longitudinal axis of the waveguide sealingly rests against the housing and the waveguide and adjoins a recess that encloses the waveguide.
