Abstract
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.

16. A level meter for measuring a level and storing a false echo, comprising:
a processor at least one of initializing and updating false echo data, the processor being designed to decide whether or not the false echo data are to be at least one of initialized and updated as a function of at least one first value, the first value corresponding to at least one property of a first noise. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A method for measuring a level and storing false echoes, comprising the steps of:
-
deciding whether or not false echo data are to be at least one of initialized and updated depending on at least one of first value, the first value corresponding to a property of a first noise; and performing, when the decision is affirmative, at least one of initializing and updating the false echo data.

29. A program element which, when implemented on a processor of a level meter, instructs the processor to execute the following steps:
-
deciding whether or not false echo data are to be at least one of initialized and updated depending on at least one of first value, the first value corresponding to a property of a first noise; and performing, when the decision is affirmative, at least one of initializing and updating the false echo data.

-
deciding whether or not false echo data are to be at least one of initialized and updated depending on at least one of first value, the first value corresponding to a property of a first noise; and performing, when the decision is affirmative, at least one of initializing and updating the false echo data.
