    摘要: For calculating the fill level in a container two echo curves are acquired that image the reflection conditions along two different measuring paths. On their way to the filling material surface or the separating layer surface the corresponding measuring signals cover different electrical distances. From the two echo curves a characteristic value can be calculated that reflects a physical characteristic of the covering medium. From this, the fill level can then be determined with increased accuracy.

    摘要: A measuring device is for determining a separating layer or a mixing ratio in a container. The measuring device comprises two fill-level measuring apparatuses that acquire the echo curves in a standpipe and outside the standpipe, respectively. Solely from these two echo curves the position of a virtual boundary layer or the mixing ratio of the two different liquids can be determined.

    摘要: The invention relates to false echo storage in the area of level measurement. The decision as to whether or not to initialize and/or update the false echo memory is made using at least one value for the sensor-inherent noise, container noise and/or EMC noise for this purpose. This may make it possible to avoid identifying a false echo as the level echo.

    摘要: In fill-level measuring devices that operate according to the FMCW principle, nonlinearity of the sensor signal depending on the time can result in measuring inaccuracies. The fill-level measuring device that operates according to the FMCW principle comprises a correction unit for the mathematical correction of the amplitude values or for calculating points in time of scanning the amplitude values on the basis of a reference correlation determined at the factory. In this way intermediate-frequency values that are identical to those of an ideal sensor can be derived.

    摘要: Described is a method for automatically initiating an update of a parasitic echo storage device in a fill level meter operating according to a runtime method. In this method individual echoes of echo curves of different ages are allocated, according to their typical echo characteristics, to global echo groups so that subsequently, after examining the behaviour over time of the echoes of the respective global echo curves, it can be judged whether the echoes of the respective global echo curves are useful echoes or parasitic echoes. Starting from this classification, the parasitic echo storage device is then updated with the oldest echoes of the corresponding global echo groups. Apart from the method for updating a parasitic echo storage device described is also an evaluation device for implementing the method as well as to a computer program and a computer program product for carrying out the method.
