C.5.5d The Advanced Features Option
This option enables you to enable the more advanced features of the meter. In this option you can do the following:
•
enter a table of K-factors (based on velocity or reynolds number) that compensates for non-linear flow rates
•
enable mass flow (calculated for static fluid density)
The Multiple K Factors Option
Use this option to enter a table of K-factors. K-factors are used to create a curve for the flow range (based on velocity
or reynolds number) that compensates for non-linear flow rates. The meter accepts from 2 to 20 pairs. Complete the
following steps to enter multiple K factors for velocity or reynolds values:
1. From the Advanced Features option menu, highlight and double-click on Multiple K Factors in the center pane.
2. Double-click on Yes to Activate Multi K Factors or on No to disable this option.
NO
If
was selected, the meter returns to the Advanced Features window. If
3. Double-click on the desired Custom Type (velocity or reynolds).
If you selected CstR (Reynolds), enter the desired Kinematic Viscosity, and click [Next Item].
•
4. Double-click on Yes to Edit the K-factor Table or on No to retain the current K-factor table (and return to the
Advanced Features window).
Note: If the necessary velocity/reynolds vs. K-factor data was not provided with the Model XGS868i's documentation,
the K-factor table cannot be edited.
NO
If
was selected, the meter returns to the Advanced Features window. If
5. Enter the Number Of K-factors (from 2 to 20) to be entered into the table, and click [Next Item].
Note: When editing the K-factor table, the velocities must be entered in increasing order.
6. Enter the Velocity/Reynolds Value for K-factor number "X" and click [Next Item].
7. Enter the K-factor corresponding to velocity/reynolds number "X" (0.333 to 3.0) and click [Next Item].
The Velocity # and K Factor # prompts repeat for each pair. After entering all the pairs, the meter returns to the
Advanced Features window.
