6 Set up with the indicating and adjustment module
VEGAFLEX 83 • 4 … 20 mA/HART - two-wire
41834-EN-120726
If you have selected "
Nein
", then you can enter the adjustment for the
interface measurement separately.
Enter the respective distance value in m for the empty vessel cor-
responding to the percentage value.
To damp process-dependent measured value fluctuations, you have
to set an integration time of 0 … 999 s in this menu item.
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. in 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 linearisation curve is selected, the measuring signal is no longer
linearly proportional to the level. This must be taken into consideration
