igh sockets or vessel installations

struts or agitators as
well as buildup and weld joints on the vessel walls cause interfering

.
A
false echo storage
detects and marks these false echoes

so that they are no longer taken
into account for the level measurement
.
A
false echo memory should
be created with empty vessel so that all potential interfering re

will be detected
