Emmerich, Technical University of Brunswick; officially recommended by ICUMSA, 20th session 1990Concentration measurement with flexible calculation functionUnder certain application conditions, it may not be possible to use density functions with a fixedcalculation function (% mass, °Brix, etc.). However, user-specific or application-specificconcentration calculations can be used with the "FLEXIBLE" setting in the functionDENSITY 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 2DCalculation type "% MASS 3D" or "% VOLUME 3D"For this type of calculation, the relationship between the three variables - concentration, density andtemperature must be known (3-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· 2 +A3· 3 +A4· 4 +B1·T+B2·T 2 +B3·T3K Concentration Currently measured 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)B1 Value from function (COEFFICIENT B1 (7037)B2 Value from function (COEFFICIENT B2 (7038)B3 Value from function (COEFFICIENT B3 (7039)T Currently measured temperature in °Ca0004620Page 72 • MN0M022Issue/Rev. 0.2 (12/12)
