摘要： Detecting the mobility of a fill level echo according to the following steps. The echo characteristic of a first echo of the echo curve and an echo characteristic of a second echo of the echo curve are determined. This is followed by calculation of a mobility value of the second echo with the use of the first echo characteristic. In this way a situation can be achieved in which the differences in the mobility values of echoes relating to the fill level and those echoes that are due to container internals become greater.

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： Methods and apparatuses for finding, extracting and for providing of echoes with detail functions are described. In particular, an echo extraction method for extracting an echo from an echo function is described. The method comprises receiving the echo function and decomposing the echo function in at least one detail function. The at least one detail function comprises a plurality of first coefficients. Each of the at least one detail functions represents a different degree of detail of the echo function. The degree of detail relates to a form of a base function. Furthermore, the method comprises eliminating at least one of the plurality of first coefficients and applying a reconstruction regulation or scheme, which depends on the form of the base function, for generating a smoothed echo function. Thereafter, at least one echo is determined from the smoothed echo function.

摘要： A level gauge carries out a tracking method with consideration of the mobility of the echoes. For this purpose, mobility values of echoes of an echo curve are determined and the expectancy function, by means of which it is determined whether a certain echo needs to be assigned to a certain track, is determined with consideration of at least one of the mobility values. In this way, the correct allocation of an echo to a certain track may be realized with high reliability.
