Abstract
A method for ascertaining and monitoring the fill level of a medium in a container via a field device, wherein transmission signals are transmitted toward the medium and are received as reflection signals. The transmission signals and the reflection signals are registered by means of data points in an envelope curve dependent on travel time or travel distance. Disturbance echo signals are registered by means of data points in a masking curve, the data points are connected with one another via connecting functions An evaluation curve is ascertained from the envelope curve; wherein, by means of a reduction algorithm, the number of data points in the masking curve and/or in the evaluation curve is reduced; and wherein, by an echo search algorithm, by means of the reduced masking curve and/or reduced evaluation curve, at least one wanted echo signal in the current envelope curve is ascertained.
