The invention relates to a device and a method for determining a predetermined level of a medium (9) in a vessel (8). In the method according to the invention a radio-frequency measuring signal is coupled onto a conductive element (6) of a predetermined length and is guided along the conductive element (6), the measuring signal is in each case reflected as a system-dependent echo signal in those regions of the conductive element (6) in which there is a sudden change in the characteristic impedance, the measuring signal is reflected as a useful echo signal when the free end of the conductive element (6) is located in the immediate vicinity of the surface (10) of the medium (9), or in contact with the medium (9), and the fact that the medium (9) has reached the predetermined level in the vessel (8) is determined on the basis of the relative position of the useful echo signal and at least one system- dependent echo signal, or on the basis of the relative position of two system- dependent echo signals.
