A device for the capacitive measurement of a level of filling having a measurement capacitor which dips into the fluids to be measured in accordance with the filling level thereof, and a unit for forming an electric value corresponding to the filling level and a unit for compensating for different dielectric constants of fluids which comprise a compensation capacitor dipping into the fluid. A circuit forms an electric value corresponding to the filling level and compensates the different dielectric constants of the fluid such that only the imaginary part of the complex conductance of the measurement capacitor and of the compensation capacitor enters into the electric value, but not the real part thereof in each case.
