Videographic Recorders SM1000 and SM2000 2 Math Configuration Mass Flow Calculation – Average density correction The average density over a given temperature range is used to calculate the mass flow as follows: Qma = Qc x Da, where Qc is the temperature compensated flow and Da (a constant) is the average density.
Note. Input a3 is the actual product temperature input (as a2 in previous examples) but with the density correction applied using a custom linearizer – see Section 4.9.1 of the User Guide (IM/SM1000 or IM/SM2000). Mass Flow – Measured Density Correction Qmm = Qc x input from density meter.
