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 "Liquid" or "Solid".
Medium
Liquid
Information:
With VEGAPULS 63 with electronics version "Increased safety",
"Solid" is preset as factory setting. However, the instrument should be
used preferably in liquids. In such cases, the medium selection should
be set to "Liquid" during setup.
According to the conductivity and the dielectric constant of liquids,
the reflection properties can differ considerably. Therefore additional
options such as "Solvent", "Chem. mixture" and "Water based" are
offered below the menu item 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, particularly in products with
poor reflective properties, is considerably increased.
Enter the requested parameters 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 bulk solid is selected. With "Liquids" these are "Storage tank",
"Stilling tube", "Open vessel" or "Stirred vessel", with "Solid", "Silo" or
"Bunker".
Vessel form
Storage tank
Information:
With VEGAPULS 63 with electronics version "Increased safety",
"Solid" is preset as factory setting. However, the instrument should be
used preferably in liquids. In such cases, the vessel form should be
set to "Storage tank" during setup.
Enter the requested parameters via the appropriate keys, save your
settings and jump to the next menu item with the [->] key.
To suppress fluctuations in the measured value display, e. g. caused
by an agitated product surface, a damping can be set. This time can
be between 0 and 999 seconds. Keep in mind that the reaction time of
