Abstract

The invention relates to a sensor system 10 for the capacitive measurement of the fill level of a fluid medium 22 in a container, preferably a bubble catcher of a dialysis device, comprising a receptacle 30 on which two contact areas are provided for contact with an external surface of the accommodated container and with at least one level detection electrode C1, C2, C11, C12, C21, C22 disposed in each contact area for capacitive detection of the fluid level in the container. The sensor system has a coupling measurement device C11, C12, C21, C22 for capacitive determination of the correct coupling.
