C.5.3b Pipe OD
4. Click on the appropriate pipe OD unit type in the
center pane from the list shown in Table 17 below.
Then enter the known pipe outside diameter or
circumference in the right pane and click [next item].
Obtain the required information by measuring either
the pipe outside diameter (OD) or circumference at the
transducer installation site. The data may also be obtained
from standard pipe size tables found in Sound speeds and
pipe size data (914-004).
Table 17: Available pipe OD units
English Metric
inch mm
feet meters
circum.in = pipe
circumference in inches
circum.mm = pipe
circumference in
millimeters
circum.ft = pipe
circumference in feet
circum.m = pipe
circumference in meters
5. Enter the known pipe wall thickness (in inches or mm)
in the right pane and click [next item].
C.5.3c Path and axial lengths
6. Click on the appropriate path length unit type in the
center pane. Then enter the path length of the ultrasonic
signal in the right pane and click [next item].
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 for instructions.
7. Click on the appropriate axial length unit type in t
he center pane. Then enter the axial length of the
ultrasonic signal in the right pane and click [next item].
C.5.3d Fluid type
8. Double-click on the appropriate fluid type , either
air or other .
• If you select other , PanaView asks for the fluid
soundspeed . Enter the appropriate soundspeed
(in ft/sec) and click [next item].
C.5.3e Reynolds Correction
9. Double-click on the appropriate choice to indicate
whether you want Reynolds Correction .
• If off is selected, enter the calibration factor
and click on [next item].
• If on is selected, enter the kinematic viscosity and
click [next item]. Then enter the calibration factor
and click [next item].
PanaView returns to the channel program menu.
You have completed entering pipe parameters.
