the up and down arrow keys to step through the list. Press
or circumference on the left side and press
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 (GE document 914-004).
inch
feet
in/PI = pipe circumference in inches
ft/PI = pipe circumference in feet
6. Use the arrow keys to enter the known Pipe Wall Thickness (in inches or mm) and press
Note: If you are using clamp-on transducers, skip to step 9 below.
2.4.3d 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
