If you have selected interface measurement under the menu item
"Application", you can adjust the damping for the level and the inter-
face separately.
The default setting is a damping of 0 s.
A linearization is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e.g. a horizontal cylindri-
cal or spherical tank, when the indication or output of the volume is
required. Corresponding linearization curves are preprogrammed
for these vessels. They represent the correlation between the level
percentage and vessel volume.
The linearization applies to the measured value indication and the
current output. By activating the appropriate curve, the volume per-
centage 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".
Caution:
Note the following, if the respective sensor is used as part of an over-
fill protection system according to WHG:
If a linearization curve is selected, the measuring signal is no longer
linearly proportional to the level. This must be taken into consideration
by the user, particularly when setting the switching point on the limit
signal indicator.
Since the scaling is very comprehensive, the scaling of the level value
was divided into two menu items.
In menu item "Level 1" you define the scaling size and the scaling unit
for the level value on the display, e.g. volume in l.
