these vessels. They represent the correlation between the level
percentage and vessel volume. By activating the appropriate curve,
the volume percentage of the vessel is displayed correctly. If the
volume should not be displayed in percent but e.g. in l or kg, a scaling
can be also set in the menu item "Display".

f a linearisation curve is selected, the measuring signal is no longer
compulsorily linear proportional to the level. This must be taken into
consideration by the user, particularly when adjusting the switching
point on the level switch.
H
igh sockets or vessel installations, such as e. g. struts or agitators as
well as buildup and weld joints on the vessel walls, cause interfering
reflections which can impair the measurement. 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 low level so that all potential interfering reflections can
be detected.
