A linearization is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e. g. horizontal cylindri-
cal or spherical tanks - and 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 the vessel volume. The linearization applies to the
measured value indication and the current output. By activating the
appropriate curve, the volume percentage of the vessel is correctly
displayed. 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.
Entering a 4-digit PIN protects the sensor data against unauthorized
access and unintentional modification. In this menu item, the PIN is
displayed or edited and changed. However, this menu item is only
available if adjustment is enabled in the menu "Setup".
In delivery status, the PIN is "0000".
