DigitalFlow™ XMT868i Programming Manual
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.
If NO was selected, the meter returns to the
Advanced Features
window. If YES was selected, proceed to Step 3.
3. Double-click on the desired
Custom Type
(velocity or reynolds).
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 XMT868i’s
documentation, the K-factor table cannot be edited.
If NO was selected, the meter returns to the Advanced Features window. If YES was selected, proceed to Step 5.
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.
