Thats a real good comparrison shot, I just sent that to all my guys as a reminder.

Went to Turbo Torch's site and they say you have to use a regulator before the flow meter and the max inlet pressure is 50 psi, is this true with all of the flow meters?

Do all flow meters have the glass or plastic indicator tube, any metal?

The prices aren't bad, $50/

Where does one find an oxygen sensor?

Thanks

A combustion analyzer has one. Just put the probe in the open end of the tubing and watch the O2 drop from 20.8% to 0%.

woa, that would be expensive, but at the end of the sensors life it would a great time to experiment to find the lowest flow rate for ones technique. Just wish they had a metal protective cover for those glass tubes.
