Air flow calculation
Since the different manufacturers have different ways of documenting their k factor and do the air flow calculations, the macro offers different calculation options.
Depending on the parameters AFL-05 (calculation option) and AFL-06 (density compensation) the formulas to calculate the air flow are shown in the next table:
calculation option |
density compensation AFL-06 |
air flow calculation formula in m3/h |

In the formulas above:
The output of the table above are scaled in cubic meter / hour will be displayed at the output "CalcAirFlow_m3ph".
The output"CalcAirFlow_lps" displays the same calculated flow but scaled in liter / second applying the fixed multiplier 1/3,6 ( 1m3/h = 1000/3600 l/s).
