The mode is used to suppress false
reflections caused by the reflection of
the ultrasonic signal from unevenness
on the tank walls, various partitions,
stirrers or other obstacles. After start -
ing this mode, the sensor detects false
reflections and stores them in memory.
After that, these false reflections will
not affect the subsequent measure -
ment (they are masked).
Before starting the mode, it is neces -
sary to drain the tank as much as pos -
sible (preferably completely).
In the case of installed stirrers, it is nec-
essary to move the stirrers to a position
below the level meter (direct the stirrer
blade into the ultrasonic signal beam).
Note: If significant obstacles occur in
the upper half of the tank, multiple
false reflections may occur, especially
in closed tanks. In such cases, it is nec -
essary to drain the level in the tank as
low as possible so that these possible
multiple false reflections are properly
masked.
