A linearization is necessary for all vessels in which the vessel volume
does not increase linearly with the level, for example, with a cylindrical
or spherical tank. Corresponding linearization curves are prepro-
grammed 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 also set.

Scaling means converting the measured value into a certain param-
eter and unit. The linearized percentage value is the source signal
which is used as basis for the scaling. The indication can then show
the volume in litres e.g., instead of the percentage value. Indication
values from max. -99999 to +99999 are possible.

In this menu item you can enter an unambiguous designation for each
measurement loop, e.g. the measurement loop name or the tank or
product designation. In digital systems and in the documentation
of larger plants, a singular designation should be entered for exact
identification of individual measuring points.

Under "Outputs" you will find the relay/current outputs. With relay
output, first of all the requested mode ("Overfill protection" or "Dry
running protection") must be selected.
