temperature of the medium within permitted limits? Did you select a
suitable ultrasonic transducers for the application with regard to the
pipe dimensions? Once again, verify that you selected the correct
ultrasonic transducer and that it is parameterized.
8 A. Which transducer mounting mode did you select?
Standard is the V-mode. If you selected the W-mode,
you should first try the V-mode.
9 A. You selected the proper transducer distance. Take the
measurements at the transducer faces. When using a spacer bar,
check the number of holes between the transducer mounting
positions acc. to chapter 7.3
10 A. Does the piping have a thick paint coating? If yes, try to
remove the paint at the position where you are planning to install
the ultrasonic transducers, e.g. using sand paper. You can never
take any measurements on piping insulation, no matter what
type of material is involved!
11 A. Did you apply an appropriate film of acoustic coupling gel
(Magnalube) to the transducer faces? Small transducers (types
XUC-PW-10 and -20) need approx. 3 cm, whereas the large
transducer (XUC-PW-05) requires approx. 6 cm of coupling gel.
12 A. Do the transducers apply adequate pressure on the piping?
13 A. Are the transducers that are mounted without spacer bar
precisely aligned along a common axis (!) on the piping?
14 A. Are there any sources of strong disturbance such as
transformers or electrical drives, or sources of vibration in the
immediate area of measurement?
14 A. Use the Z-mode for installation if all of your efforts did not
yield a satisfactory result. Parameterize your device accordingly.
You might also try to test your equipment on a different piping
section that is close by in order to find out whether or not you can
perform a measurement. Check all measuring leads for damage.
