5.16 – K-FACTOR CONFIGURATION
Caution
In the majority of applications, the use of a K-Factor is neither required nor desirable.
Before using the K-Factor feature, contact the Service Department (see Section 10) to review
the application and obtain assistance in determining the K-Factor gain and bias values.
User can turn K-Factor function ON or OFF, calculate a K-Factor gain and bias based on measured data, or select a K-
Factor gain value and K-Factor bias value. The K-Factor gain is a number applied as a multiplier to the differential
pressure and the K-Factor bias is an offset added to the differential pressure. Note: If K-Factor is ON, Process
displays will have an asterisk (*) after the description (i.e. FLOW*).
