linearization is necessary for all vessels in which the vessel
volume does not increase linearly with the level - e. g. with a
cylindrical or spherical tank - 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 vessel volume.
B
y activating the appropriate curve, the volume percentage 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".

f a linearisation curve is selected, the measuring signal is no
longer compulsorily linear proportional to the level. This must
be taken into consideration by the user, particularly when
adjusting the switching point on the level switch.
I n this menu item you can enter an unambiguous designation
for the sensor, e.g. the measurement loop name or the tank or
product designation. In digital systems and in the documen-
tation of larger plants, a singular designation should be entered
for exact identification of individual measuring sites.
