Means for detecting a water level

To electrically means (1) for detecting a level object (3) from the media (4), preferably in a tank (2, 200) so as to protrude with a substantially vertically in the tank (2, 200) of this insulated attachable elongated electrical lead conductor (6), an electrical time-variable generator (7) with an internal impedance (Zg) for connection to a feed point (11) of the probe head (6), for applying to this a time-variable voltage, said feed point (11) one end, particularly at the tank-side end of the probe guide (6) is arranged, and an evaluation and / or control unit (9) (9) for evaluating an electrical variable of the probe head (6), indicate which a water level of any media, in particular liquid, paste-like and / or granular solid media, as simple as possible, fault tolerant and can grasp cost, it is suggested that the evaluation and / or control unit (9) for measuring a Fuspunktimpeda nz of the probe head (6) is formed at the feeding point (11).
