Patent ID: 8670950

Claim:
A level meter for measuring a level and storing a false echo, comprising: a processor for 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, wherein the processor is further 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 second value, the second value corresponding to at least one property of a second noise, wherein the second noise is at least one of a sensor-inherent noise, a container noise and an EMC noise, wherein the processor is designed to determine whether the first value is greater than the second value, and wherein the processor is designed to activate a fault memory updating mode if the first value is greater than the second value.
