If there are problems with your measurement SN can be improved by:
•
Surface of pipe: Remove painting or rust
•
Coupling grease: Use sufficient 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 mounted e.g. on welding
seams
•
Make sure to remove air from your liquid (deareate)
•
Choose another mounting position (e.g. vertical pipe)
•
Make sure to provide sufficient straight run
•
Make sure that signal cables are not disturbed by power cables
•
Especially pumps and motors (with frequency inverters) generate
electric noise and should be avoided to be nearby
•
Use Z-mode rather than V-mode to reduce path length and
therefore to increase signal strength
•
Use V-mode rather than W-mode
•
Use stronger transducers, e.g. –F05 instead of –F10 or –F10
instead of –F20
