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 Entering global system data
on page 12 .
• To continue regular programming, refer to Appendix A,
menu maps , to navigate to the desired menu.
• To leave the keypad program , press the [escape]
key twice.
