A method for a fill level measurement in which a first and/or a second fill substance can be located. A rest position can be ascertained, when the entire amount of each fill substance in the container forms a single layer containing only this fill substance, wherein the first fill substance has a smaller specific weight than the second fill substance, and the two fill substances have different dielectric constants. An electromagnetic signal is sent into the container, wherein a part of the signal is reflected. A capacitance between a capacitive probe and a reference electrode is measured, dependent on the amounts of the fill substances located in the container, and, on the basis of the measured capacitance and the measured travel times for each fill substance present in the container, the rest position of its fill substance upper surface is ascertained.
