This function can be used to make the Doppler flow meter system agree with a different or reference flow meter, or to compensate for an installation where there is inadequate straight pipe to obtain a laminar flow profile, by applying a correction factor/multiplier to the readings and outputs. The range of settings for this entry is 0.500 to 2.0. The following example describes using the SCALE Factor entry.
The Doppler flow meter is indicating a flow rate that is 3.0% higher than another flow meter located in the same pipe line. To make the Doppler flow meter indicate the same flow rate as the other meter, enter a value of 0.970, to lower the readings by 3.0%.
