Variable Name: sc_fo
Variable ID: 0x409D
Variable Label: Fraction offset
Variable Help: Fraction is defined as a part of a mixture. Mixtures consist of two components (A+B), which can be measured separately. If the flowmeter is ordered with fraction, e.g. °BRIX, the flowmeter is able to calculate the % concentration of sugar in a water (B) + sugar (A) mixture. With this fraction offset you are able to make an absolute offset on the measured concentration. Formula: % concentration = ( a / 3600 ) + bx % concentration = the concentration of media e.g. in °BRIX a = fraction offset in ( kg/h ) b = is a factor without dimension ( table slope ) x = is the concentration in % or e.g. °BRIX Example: If you want to make an offset on + 1 °BRIX you have to make following calculation: a/3600 has to be 1%. a/3600 =0,01 a = 0,01x3600 = 36 kg/h Fraction A is in this example the calculated flow rate of 100 % pure sugar, and Fraction B is the calculated flow rate of 100 % pure water.
