Chapter 2. Initial Setup
2.4.3.3 Pipe OD
5. To select the appropriate Pipe OD Unit type from the list shown in Table 16, scroll to the right side of the screen,
and use the up and down arrow keys to step through the list. Press [Enter] . Then enter the known pipe outside
diameter or circumference on the left side and press [Enter] .
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).
6. Use the arrow keys to enter the known Pipe Wall Thickness (in inches or mm) and press [Enter] .
If you are using clamp-on transducers, skip to step 9 below.
2.4.3.4 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 , for
instructions.
8. In the same manner, enter the appropriate Axial Length L unit type and axial length of the ultrasonic signal, and
press [Enter] . Skip to step 10 on page 16.
2.4.3.5 Pipe Lining
9. Scroll to the appropriate choice to indicate whether you have a Pipe Lining.
a.
If you have selected Yes , then select the Lining Material from the supplied list.
• If OTHER is selected, enter the lining sound speed, and press [Enter] .
b. Then enter the lining thickness and press [Enter] .
