1.6.2a Path and axial lengths
7. To enter the
path length
:
a. Use the [
] arrow key to highlight the path length
unit type at the right of the screen. Then use the [
]
and [
] arrow keys to scroll to the desired unit type.
b. Use the [
] arrow key to return to the numeric entry
on the left, and enter the path length of the ultrasonic
signal. Press [enter].
NOTE:
If a spoolpiece was ordered with the meter, the
transducer signal path length (P) and the transducer signal
axial length (L) are engraved on the flowcell and/or are
included in the documentation supplied with the meter.
For on-site transducer installations, refer to
Appendix C,
measuring P and L dimensions
, in the
Startup Guide
.
8. In the same manner, enter the appropriate
axial
length L
unit type and axial length of the ultrasonic signal,
and press [enter].
9. Scroll to the desired
fluid type
and press [enter]. Then do
one of the following:
• If
other
was selected - proceed to step 10.
• If
air
was selected - proceed to step 11.
10. Use the arrow keys to enter the
fluid soundspeed
(in feet
per second) in the gas to be measured and press [enter].
11. Scroll to the appropriate choice to indicate whether you
want
Reynolds Correction
, and press [enter].
• If off is selected, go to step 12.
• If on is selected, the program asks for the
kinematic
viscosity
. Use the arrow keys to enter the desired value,
and press [enter].
12. Use the arrow keys to enter a value for the flow
calibration
factor
and press [enter]. The default value is 1.00, but
values between 0.50 and 2.0 may be entered.
Procedure options
After entering the
calibration factor
, the XGF868i returns to
the channel
program
. Do one of the following:
• To continue entering
“quick startup”
data, press [escape]
once and proceed to step 1 in
• To continue regular programming, refer to
Appendix A,

, to navigate to the desired menu.
• To leave the
keypad program
, press the [escape]
key twice.
