Figure 86 Liquid K-factor Curve
Up to 20 flow rates with a corresponding K factor can be entered. When less are needed, leave
the others blank. Always start with the lowest flow rate and make sure the rest is entered in
ascending order.
The factors obtained during calibration/proving of a meter which are the corrections needed to
linearise the meter. This is expressed by a variation of the K-factor over the specified flow range.
So for each flow rate a different K-factor is used. In between the given flow rates a linear inter-
polation is used. For flow above maximum extrapolation is used.
6 .4 .3 Gas and steam flow rate correction
For more details see section: Meter Corrections
Figure 87 Gas or steam flow rate correction for a 6 point calibration
Meters may be calibrated on different flow rates to determine the deviation from a standard. The
result is an error curve. For meter correction this curve can be entered as a table of data points
of flow rate and corresponding error.
