ABSTRACT:
For measuring the filling level of a measuring medium, including detecting multiple medium layers and interfaces between them, a multi-sensor probe can be dipped into the measuring medium and longitudinally segmented into a plurality of segments, each segment comprising a sensor for measuring a predetermined physical parameter of the surrounding medium. To provide an accurate, reliable and robust measurement of multiple medium layers a measurement model is defined for modeling signals of the sensors as a function of positions of a number of interfaces between the medium layers and the physical parameters of the medium layers. Prior distributions of the number of the interfaces, the positions of the interfaces and the physical parameters of the medium layers are defined. Based on the measurement model and the prior distributions a joint posterior distribution of the number of the interfaces and the positions of the interfaces is determined. The joint posterior distribution of the number of the interfaces and the positions of the interfaces is evaluated based on Markov Chain Monte Carlo methods.
