A capacitively operating apparatus () has a container, a probe () movable into and/or out of the container, an input signal generator connectable to the probe () to provide an input signal (s(t)) which produces at least one output signal (s(t) in the probe (), and a measuring apparatus (M) connectable to the probe () to tap the output signal (s(t)) from the probe (), and wherein the probe () is periodically chargeable and dischargeable, the output signal (s(t)) corresponds to the time progression of a charging/discharging curve which is produced by the periodic charging and discharging of the probe (). The apparatus () also includes a circuit module () with two comparators for providing a first comparator output signal (PWM) and a second comparator output signal (PWM) from the output signal (s(t)) and to correlate them with one another.
