Abstract: A measuring system for determining a filling volume of a filling material in a container comprises a 3D camera and a radar-based fill-level measurement device. The 3D camera is used to initially record at least one 3D image of at least one partial region of the empty container interior. Based on the 3D images, a data set or a digital spatial model is created by which at least such partial region the geometry of the empty container interior is represented. To create the required, three-dimensional surface or level profile, the fill-level measurement device is based on a principle of digital beam shaping, such as the MIMO principle. Thus, based on the data set reflecting the geometry in the container interior and based on the fill-level profile, the filling volume in the container can be determined.

Abstract: Disclosed is a sensor arrangement on a process installation comprising at least two sensor tiles, wherein each sensor tile comprises a support and a plurality of sensors arranged on the support for determining a physical or chemical variable of a measuring medium, a process characteristic of the measuring medium, and/or a state of the process installation.

The first control unit of the first sensor tile and/or a second control unit allocated to the sensor arrangement is designed to weight the values determined by each sensor tile. Weighting may be a function of the measured value variations of the sensor tile, the position of the sensor tile in the process installation, and/or the function of the sensor tile.

Abstract: Disclosed is a fill-level measuring device for determining the fill level in a container. The device comprises: a radar module for determining a distance to the surface of the filling material; a 3D camera for capturing at least one region of the surface of the filling material; and an evaluation circuit that is designed to measure a maximum distance and a minimum distance from the captured distance values and to determine the fill level on the basis of the distance, providing that the distance is smaller than the maximum distance value and greater than the minimum distance value. As a result of the redundancy or the verification provided by the 3D camera of the distance calculated by the radar module, the fill-level measuring device according to the invention is therefore more reliable with regard to the miscalculation of an incorrect fill level.

Abstract: The invention relates to a frequency converter circuit for a radar-based distance-measuring device. The core of the frequency converter circuit is a non-linear, high-frequency component, having a frequency connection point and a signal connection point, which serves as a signal input for a low-frequency input signal. On the reception side, the frequency converter circuit comprises at least one receiving antenna for receiving the high-frequency reception signal and a non-linear semiconductor component for downconverting the high-frequency reception signal. The frequency converter circuit therefore uses the effect that, by means of the low-frequency input signal, corresponding harmonic waves are induced at the non-linear, high-frequency component. Furthermore, the high-frequency reception signal is downconverted into a low-frequency evaluation signal, whereby the further determination of the distance can be performed on the basis of the low-frequency evaluation signal, which can be processed more easily.

Abstract: The invention relates to a method for measuring fill level of a substance in a container. The method is based on pulse radar in which the repetition frequency of the microwave pulse is not constant but is controlled as a function of travel time. The repetition frequency increases as the travel time becomes shorter and lessens as the travel time becomes longer. The fill level is not based on the measured travel time, but is determined based on the resulting repetition frequency. The invention provides a pulse radar-based method for fill level measurement that can be implemented with reduced circuit complexity. This results from the fact that only the repetition frequency needs to be registered for fill level measurement. Neither a complex analog evaluating circuit nor a highly accurate time measurement are required. Complex digital data processing, such as the FMCW-based method required for fill level measurement, is absent.
