摘要
A method of filling level measurement in a container (12) having a first medium (14) and at least one second medium (16) arranged thereabove, in particular a foam layer, wherein an electromagnetic signal is transmitted, in particular along a probe (28) arranged in the container (12), and a signal curve (S) of the signal reflected in the container (12) is recorded, wherein a signal time of flight (t) up to a border transition (18, 20) to the first medium (14) and/or up to the second medium (16) is determined with reference to the signal curve (S) and a filling level of the first medium (14) and/or a filling level of the second medium (16) is determined from the signal time of flight (t). In this respect, the border transition (18, 20) is recognized from the integral over the signal curve (S), the integral starting from a reference position (t0).
