    摘要: A method for checking proper functioning of a fill-level measuring device working according to the travel time principle. For this purpose, in predetermined or selectable time intervals (ta), a current measured value curve at a current fill level (hactual) is ascertained; on the basis of the current measured value curve, a current wanted echo signal is determined. Subsequently, on the basis of the current wanted echo signal, an expected value (E) for quality of a wanted echo signal at at least one predetermined fill level (hdesired) is ascertained. The ascertained expected value (E) for quality of the wanted echo signal at the predetermined fill level (hdesired) is compared with a predetermined critical value for quality, and an error condition is diagnosed, when the ascertained expected value falls below the critical value for quality.

    摘要: 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.
