Chapter 2. Initial Setup
2.7.2 Pipe Data
If either a standard or a special transducer is being used, the programming sequence should be rejoined at this
point.
5. To select the appropriate Pipe OD Unit type from the list shown in Table 10, scroll to the right side of the screen,
and use the up and down arrow keys to step through the list. Press [Enter]. Then use the arrow keys to 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 the pipe wall
thickness is not available, look up the value in a table of standard pipe size data which can be found in the Sound
Speeds and Pipe Size Data manual (914-004).
2.7.2.1 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.

inch mm = millimeters
feet m = meters
in/PI = pipe circumference in inches mm/PI = pipe circumference in millimeters
ft/PI= pipe circumference in feet m/PI = pipe circumference in meters
