The invention relates to devices for detecting the fill level of media in containers.The devices are distinguished, in particular, by a simple and reliable detection of the fill level.For this purpose, multiple measuring points, each consisting of a series circuit of a resistor and a p-n junction, are spaced apart from one another. Each measuring point is connected, on the one hand, to an input of a multiplexer. On the other hand, the measuring points are connected to a reference potential. The output of the multiplexer is connected to a control device, wherein the control device isa control device periodically supplying a voltage to the measuring point connected to the control device via the multiplexer and measuring the voltage drop,a control device determining the medium from the temperature-dependent forward voltages resulting from the different thermal properties of the medium anda control device ascertaining the fill level from the consecutive measuring points.
