Provided is a method for process monitoring in automation technology based at least on one capacitive and/or conductive measuring probe for determining at least one process variable of at least one medium in a container, an apparatus suitable for executing the method, as well as a computer program and a computer readable medium. The method includes method steps of ascertaining whether the measuring probe is at least partially in contact with the medium and registering as a function of time at least an electrical conductivity of the medium, a dielectric constant of the medium and/or a degree of coverage of the measuring probe by the medium. The method also includes a step of monitoring the process running within the container based on the electrical conductivity, the dielectric constant and/or the degree of coverage as a function of time.

Method for process monitoring

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.
