ith VEGAPULS 61 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.
A ccording to the conductivity and the dielectric value 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.
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.
E nter the requested parameters via the appropriate keys, save your
settings and jump to the next menu item with the [->] key.
A part 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".
