[SBE] Ultrasonic Leak Detection

[Bill Croghan]

Just thinking out load,  I've never tried it, but has anyone tried putting
hot air into the line then watching with an infrared scope for where it
might be coming out?  The heated air would have to be cool enough to be safe
but warm enough not to cool off to much going up the line.   Maybe the leaks
would be to slow, and of course it would have to be done on a cool but not
cold day.  I have had no experience with infrared scopes, but know that they
have been used successfully to spot hot spots on Tx lines caused by shorts,
bad bullets etc.
