reference plane (seal surface of the process fitting). Keep in mind that
the max. level must lie below the dead band.
In this menu item, you can enter the min. adjustment for the level.
Adjust the requested percentage value with [+] and save with [OK].
Enter the suitable distance value in m for the empty vessel (e.g.
distance from the flange to the probe end) corresponding to the per-
centage value. The distance refers tot he sensor reference plane (seal
surface of the process fitting).
To damp process-dependent measured value fluctuations, set an
integration time of 0 … 999 s in this menu item.
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".
