8.3.4.4 Filling speed
Parameter: P26 Default value: 50 m/h
Path: OPTIMIZATION / FILLING SPEED
Description: This parameter provides additional protection against
echo loss in applications involving very heavy fuming
during filling process. Correct setting increases the
reliability of the measurement during the filling. The
parameter must not be smaller than the fastest possible
filling rate of the actual technology.
8.3.4.5 Background Image
Parameter: OPTIMIZATION / BACKG.ECHO IMAGE / SAVE
BACKG. IMAGE
Path: The not-moving disturbing objects inside the tank which
generates unwanted false reflections can be blocked out
from the measurement range. For this purpose the
instrument needs to map the totally empty tank to create
a ”background image”. After this procedure the software
will automatically recognise and ignore the reflections
coming from the disturbing objects crossing the
microwave beam (see 6.1 - Obstacles).
Warning! The background image should be saved only
when the tank does not contain measurement medium
but the disturbing objects inside the tank are not
removed. The background image is not recommended
to be saved when the tank is filled with the
measurement medium since it might result wrong level
measurement.

8.3.4.6 Using saved background image
Parameter: P35: a, where a: 0, 1 Default value: OFF
Path: OPTIMIZATION / BACKG.ECHO IMAGE / SAVE
BACKG: IMAGE
Description: Turning ON or OFF the usage of saved background
image during the calculations as per the above 8.3.4.5
point described.

OFF: Ignoring the saved background image.

ON: Saving background image, damping reflections
coming from the disturbing objects.
