If there are problems the sharpness can be increased by:
•
Choose different signal sequence (described later)
•
Use other mounting mode
•
Use different transducer
•
Pipe surface: Remove painting and/or rust
•
Make sure to use sufficient amount of coupling grease
(Magnalube)
•
Alignment of transducers: Make sure that transducers are mounted
as suggested by deltawaveC-P. Please also make sure that center
of transducers touches the pipe sufficiently (might be problem at
very small pipes). You can check the oscilloscope while mounting
the transducers.
•
Make sure that transducers are not blocked e.g. by welding seams
•
Choose a different location for your measurement
To select a different signal sequence please enter the diagnostic menu
(Diag) and press button on the right of parameter SendCode. Usually the
signal sequences 3-Barker 5 or 4-Barker 7 are expected to bring best
performance. You can try different sequences and check influence in
diagnostic data (SigQ, see chapter 14.1.2) as well as visually in
oscilloscope.
