An apparatus for ascertaining and/or monitoring fill level of a medium in a container. The apparatus includes an antenna, which transmits and receives high frequency signals in a predetermined oscillatory mode in a bounded space in a predetermined radiation direction, wherein, in front of the antenna in the radiation direction, an antenna protection element of a material transmissive for the high frequency signals is provided, and wherein a control/evaluation unit is provided, which evaluates the received high frequency signals and ascertains the fill level.

Apparatus for determining and/or monitoring the level of a medium

The invention relates to a measuring device which determines the filling level by means of high-frequency measuring signals which are guided along a waveguide. The invention is based on the object of optimizing the waveguide. According to a preferred embodiment of the apparatus according to the invention, the waveguide is a wire cable which comprises a plurality of individual wires of a predetermined diameter which are twisted together.

Apparatus for determining and/or monitoring the filling level of a product in a container

A securement system for a measuring device for monitoring and/or determining a fill level of a medium in a container, with at least one device housing and at least one elongated unit. In the device housing, at least one cutting ring is provided, which cuts into the outer layer of the end of the elongated unit far from the process in such a manner that the elongated unit is connected with the device housing electrically, pressure tightly and/or resistantly against pull.

Fixing system for a measuring device for monitoring and/or determination of a filling level

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.

Level meter

A measuring device for determining the filling level of a product or the position of the interface between two media or phases in a container by means of high-frequency measuring signals which are guided along a waveguide. The waveguide comprises a wire cable with a plurality of individual wires of a predetermined diameter which are twisted together.

The invention relates to a filling level measuring device which is used to measure the level of a filling material in a container. A probe is provided, which protrudes inside the container. The filling level measuring device can be mounted and dismounted without the probe needing to be moved in the container. The inventive device comprises a housing consisting of a first section, and a second section, the sections respectively comprising a central axial bore whereby the first section has an interior diameter which is smaller than that of the second section. A securing device is provided on the housing for securing the filling level measuring device onto the container. An insert is disposed in the housing in such a way so that it can pivot in relation to the housing, the insert being placed on a surface between the first and the second sections. A probe protrudes into the container and a connecting element is provided which connects the insert and the sensor along a prolongation of a longitudinal axis of the probe.
