Calculation type "% MASS 2D" or "% VOLUME 2D"
For this type of calculation, the relationship between the two variables concentration and
reference density must be known (2-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):
a0004621
K
Concentration
rref
Currently measured reference density
A0
Value from function (COEFFICIENT A0 (7032))
A1
Value from function (COEFFICIENT A1 (7033)
A2
Value from function (COEFFICIENT A2 (7034)
A3
Value from function (COEFFICIENT A3 (7035)
A4
Value from function (COEFFICIENT A4 (7036)
!
Note!
Promass determines the reference density by means of the density and temperature
currently measured. To do so, both the reference temperature (function REFERENCE
TEMPERATURE) and the expansion coefficients (function EXPANSION COEFF) must be
entered in the measuring system.
The parameters important for measuring the reference density can also be configured
directly via the "Commissioning" Quick Setup menu.
Calculation type "OTHER 3D" or "OTHER 2D"
With this option, users can enter a free selectable designation for their specific
concentration unit or target parameters (see function TEXT ARBITRARY CONCENTRATION
(0606)).
