Entering Parameters for Wetted Transducers (cont.)
3W. Entering the Pipe Wall Thickness
Enter the thickness of the pipe wall. If you are not sure of the pipe
wall thickness, use either the on-line help or consult the brochure
Sound Speeds and Pipe Size Data that contains some standard
pipe sizes with their corresponding wall thicknesses. For higher
accuracy, the pipe wall thickness can be determined by using the
optional internal ultrasonic thickness gage as described in
Chapter 9.
Use the numeric keys to enter the pipe wall thickness and press
[ENT].
4W. Entering the Path Length (P)
Enter the path length (P) of the ultrasonic signal. GE Panametrics
has calculated the path length based on the transducer
configuration for your particular application. Find the path length
on the flowcell or on other supplied documentation.
a. Press the appropriate feature key to select the desired units.
b. Use the numeric keys to enter the path length.
c. Press [ENT].
Note: If the path length is not supplied, refer to Appendix B to
measure the path length.
