like Microsoft Excel. Then by applying a linear or polynomial trend line, a correction curve is obtained.
The coefficients from the correction curve can be entered into fields A0 through A5 to obtain a Velocity
with very good relative accuracy. See Operation section for more detail. From the factory, Velocity is
always the same as Raw Velocity. The constants shown below result in a correction curve of y = x, or
Velocity = Raw Velocity.
4.3.3.1.3 Configuration: Outputs: Computed: Actual Volumetric Flow
Actual Flow is the volumetric flow rate at stack temperature and pressure.
4.3.3.1.4 Configuration: Outputs: Computed: Standard Volumetric Flow
Standard Flow is the volumetric flow rate corrected to the reference temperature and pressure specified
in the
