Appendix B Application Notes
Measuring pipe and tubing
When a piece of pipe is measured to determine the thickness of the pipe wall, the
orientation of the transducer is of importance. If the diameter of the pipe is larger than
approximately 4 inches, measurement should be performed with the transducer orien-
tated in the way that the gap in the surface of the sensor is perpendicular (at right
angle) to the long axis of the pipe.
For smaller pipe diameters, two measurements should be performed, one with the sur-
face gap of the sensor perpendicular, another with the gap parallelto the long axis of
the pipe. The smaller one of the displayed values should be taken as the thickness of
that point.
