C.5.5b The default setup option
Use this option to initialize (reset) all of the parameters
within the set up signal menu back to their default values.
Complete the following steps to reset all of the parameters:
1. From the set up option menu, highlight and double-click
on
default setup
in the center pane.
2. Double-click on
no
to keep the current values or on
yes
to reset all values to their default settings. After
responding to the above prompt, the meter returns
to the set up option window.
C.5.5c The v averaging option
Use this option to specify the number of readings that
occur before the meter will respond to a step change in
flow rate. In general, the smaller the number of readings,
the less steady the display will appear. Complete the
following steps to set the response time:
1. From the set up option menu, highlight and double-click
on
v averaging
in the center pane.
2. Double-click on the desired
response time
(from 1 to 60 sec).
For best results, select the STATS (statistics) option, as this
increases the response time under steady flow conditions
while still allowing a rapid response to changes in flow rate.
After responding to the above prompt, the meter returns to
the set up option window.
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.
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).
If NO was selected, the meter returns to the
advanced
features
window. If YES was selected, proceed to step 5.
NOTE:
If the necessary velocity/Reynolds vs. K-factor data
was not provided with the XGF868i’s documentation, the
K-factor table cannot be edited.
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.
The mass flow option
Use this option to calculate mass flow from a static fluid
density. Complete the following steps to enter the static
density of the fluid:
1. From the
advanced features
option menu, highlight
and double-click on
mass flow calculation
in the
center pane.
2. Double-click on
yes
to activate
static density
or on
no
to disable this option. (If you select no, PanaView
returns to the advanced features window.)
3. Double-click the
density type
(fluid density (Rho)
or molecular weight (Mw)) and click [next item].
4. Do one of the following:
• If you selected Rho - proceed to step 5.
• If you selected Mw - proceed to step 7.
5. Double-click the type of volumetric units (standard
- StVOL or actual-AcVOL) for the measurement data
display and click [next item].
6. Enter the
fluid density
(0.00001 to 0.100 lb/ft
3
or 0.00001
to 123.18 kg/m
3
) and click [next item]. PanaView returns
to the
advanced features
window.
7. Enter the
molecular weight
and click [next item].
After responding to the above prompt, the meter returns
to the
advanced features
window. Click [exit page] three
times to return to the
site edit
menu
.
