generation, material cones and echoes from the
vessel wall (with solids). To adapt the sensor to
these different conditions, you should first select
"Liquid" or "Solid".
Medium
Liquid
With solids, you can also choose between "Pow-
der/Dust", "Granular/Pellets" or "Ballast/Pebbels".
Through this additional selection, the sensor is
adapted perfectly to the product and measurement
reliability, particularly in products with bad reflective
properties, is considerably increased.
Enter the requested parameter via the appropriate
keys, save your settings and jump to the next menu
item with the [->] key.
Vessel form
Apart from the medium, the vessel shape can also
influence the measurement. To adapt the sensor to
these measuring conditions, this menu item offers
different options depending on whether liquid or
solid is selected. With "Liquid" these are "Storage
tank", "Stilling tube", "Open vessel" or "Stirred
vessel", with "Solid", "Silo" or "Bunker".

keys, save your settings and jump to the next menu
item with the [->] key.
Damping
To suppress fluctuations in the measured value
display, e.g. caused by an agitated product sur-
face, an integration time can be set. This time can
be between 0 and 999 seconds. Keep in mind that
the reaction time of the entire measurement will
then be longer and the sensor will react to
measured value changes with a delay. In general, a
period of a few seconds is sufficient to smooth the
measured value display.

keys, save your settings and jump to the next menu
item with the [->] key.
Linearisation curve
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. 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
in the menu item "Display".

Sensor-TAG
In this menu item, a clear identification can be
assigned to the sensor, e.g. the measurement loop
name or the tank or product name.

finished and you can now jump to the main menu
with the [ESC] key.
Gating out of false signals
High 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 measurement. A false echo
