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".
