VEGAFLEX 82 • 4 … 20 mA/HART two-wire

Adjust the requested percentage value with [+] and store 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".
Warning:
If a linearization curve is selected, the measuring signal is no longer
necessarily linear to the filling height. This must be considered by the
user especially when adjusting the switching point on the limit signal
transmitter.
In the following, you have to enter the values for your vessel, for
example the vessel height and the socket correction.
For non-linear vessel forms, enter the vessel height und the socket
correction.
For the vessel height, you have to enter the total height of the vessel.
