Each product has different reflective properties. In addition,
there are various interfering factors which have to be taken into
account: agitated product surfaces and foam generation (with
liquids); dust generation, material cones and echoes from the
vessel wall (with solids). To adapt the sensor to these different
conditions, you should first select in this menu item "Liquid" or
"Solid".
Medium
Liquid
With solids, you can also choose between "Powder/Dust",
"Granular/Pellets" or "Ballast/Pebbels".
Through this additional selection, the sensor is adapted
perfectly to the product and measurement reliability, partic-
ularly 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.
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".

your settings and jump to the next menu item with the [->] key.
To suppress fluctuations in the measured value display, e.g.
by fluctuating product surfaces, an integration time can be set.
This time can be between 0 and 999 seconds. Keep in mind
that also the reaction time of the complete measurement will
be bigger and the sensor will react on measured value
changes with a delay. In general a time of a few seconds will
be sufficient to smooth the measured value display.
