requested position with [->]. Set the requested percentage value
with [+] and save with [OK]. The cursor jumps now to the distance
value.

distance from the sensor to the vessel bottom) corresponding to
the percentage value.

2 E nter the appropriate distance value in m (corresponding to the
percentage value) for the full vessel. Keep in mind that the max.

E ach 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
fi
rst select "Liquid" or "Solid".
M edium
Liquid
W ith solids, you can also choose between "Powder/Dust", "Granular/
Pellets" or "Ballast/Pebbels".
T hrough this additional selection, the sensor is adapted perfectly to the
product and measurement reliability, particularly in products with bad
reflective properties, is considerably increased.
