'HILQLWLRQ RI VWLUULQJ HOHPHQW
A mathematical model (performance characteristic) of the stirring element described by the
parameters a0, b0, a1, b1 is used to calculate the viscosity.
The parameters are determined empirically for various calibration liquids and are only valid for the
defined viscosity range as well as the recommended speed range of the stirring element.
User-specific stirring elements can also be entered in this list.
VLV = Very Low Viscosity 1 to 100 mPas Aqueous media
LV = Low Viscosity 100 to 1 000 mPas Light oil
MV = Medium Viscosity 1 000 to 10 000 mPas Heavy oil
HV = High Viscosity 10 000 to 100 000 mPas Pastes, creams
VHV = Very High Viscosity 100 000 to 500 000 mPas Tar, dough
Proceed as follows:
1. Call up the parameter window by clicking the 6WLUULQJ HOHPHQW FRQILJXUDWLRQ ... command
in the "Tools" pulldown menu.
2. Enter the parameters a0, b0, a1, b1.
3. Enter the diameter of the stirring element.
4. Enter the diameter of the stirring element.
