COR FTR -- Correction Factor (Value)
(0.500 – 1.500)
This function can be used to make the TFX system agree with a
different or reference flow meter by applying a correction factor/
multiplier to the readings and outputs. A factory calibrated system
should be set to 1.000 (no correction factor). The range of settings
for this entry is 0.500 to 1.500. The following example describes a
possible use for the Correction Factor entry.
Example: The TFX meter is indicating a flow rate that is 4% higher
than another flow meter located in the same pipe line. To make the
TFX indicate the same flow rate as the other meter, enter a
Correction Factor of 0.960 to lower the readings by 4%.
