Fig. 7: Parameterisation example, Min./max. adjustment
1 Min. level = max. measuring distance
2 Max. level = min. measuring distance
3 Reference plane
The actual product level during this adjustment is not important,
because the min./max. adjustment is always carried out without
changing the product level. These settings can be made ahead of
time without the instrument having to be installed.
High 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 reflec-
tions can be detected.
