Commissioning Proline Promass 83Calculation type "% MASS 2D" or "% VOLUME 2D"For this type of calculation, the relationship between the two variables concentration and referencedensity must be known (2-dimensional), e.g. by a table. In this way, the concentration can becalculated 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):K=A0+A1· +A2· +A3· +A4· 2 3 4 ref ref ref refK Concentrationref Currently measured reference densityA0 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)a0004621!Note!Promass determines the reference density by means of the density and temperature currentlymeasured. To do so, both the reference temperature (function REFERENCE TEMPERATURE)and the expansion coefficients (function EXPANSION COEFF) must be entered in the measuringsystem.The parameters important for measuring the reference density can also be configured directly viathe "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 unitor target parameters (see function TEXT ARBITRARY CONCENTRATION (0606)).Page 74 • MN0M022Issue/Rev. 0.2 (12/12)
