A

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".

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.

H

igh sockets or vessel installations, such as e. g. struts or

agitators as well as buildup and weld joints on the vessel walls
cause interfering reflections which can impair the measure-
ment. A false echo storage detects and marks these false
echoes, so that they are no longer taken into account for the
