Concentration measurement with flexible calculation function
Under certain application conditions, it may not be possible to use density functions with a
fixed calculation function (% mass, °Brix, etc.). However, user-specific or application-specific
concentration calculations can be used with the "FLEXIBLE" setting in the function
DENSITY FUNCTION (7000).
The following types of calculation can be selected in function MODE (7021):
• % MASS 3D
• % VOLUME 3D
• % MASS 2D
• % VOLUME 2D
• OTHER 3D
• OTHER 2D
Calculation type "% MASS 3D" or "% VOLUME 3D"
For this type of calculation, the relationship between the three variables - concentration,
density and temperature must be known (3-dimensional), e.g. by a table. In this way, the
concentration can be calculated from the measured density and temperature values by
means of the following formula (the coefficients AO, A1, etc. have to be determined by the
user):
