Abstract: A level measuring device for level and/or limit determination and for measuring an impedance of a filling material is provided. The level measuring device comprises a measuring probe, arranged for measuring the impedance of the filling material. Further comprising a signal generation unit, arranged for generating a first frequency signal with variable frequency, wherein the measuring probe is supplied with the first frequency signal and outputs a measuring signal. Further, a measurement converter arranged to convert the measurement signal into a mixed signal, wherein the mixed signal has a phase difference with respect to the first frequency signal. Furthermore, the level measuring device comprises a phase difference measuring unit, which is arranged to determine an amplitude-phase characteristic of the filling material measured by the measuring probe, by means of the phase and amplitude difference between the first frequency signal and the mixed signal.
