A linearization is necessary for all vessels in which the
vessel volume does not increase linearly with the level -
e.g. in a cylindrical or spherical tank - and the indication
or output of the volume is requested. Corresponding
linearization curves are preprogrammed for these
vessels. They represent the correlation between the
level percentage and vessel volume. By 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
set in the menu item Display.

Enter the requested parameter via the respective keys,
save your settings and jump to the next menu item with
the [–>] key.
In 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 documentation of larger plants, a
unique designation should be entered for exact identi-
fication of individual measuring sites.

With this menu item, the Basic adjustment is finished
and you can now jump to the main menu with the [ESC]
key.
High sockets or vessel installations, such as e.g. struts
or agitators as well as buildup and weld joints on the
vessel walls cause false reflections which influence the
measurement. A false echo storage detects and marks
these false echoes so that they are no longer taken into
