Donald,
My experience with mass flow controllers is very limited and I bow to your experience on this matter but if there is no pressure differential, there is no flow.

I suspect that you have touched upon his trouble by suggesting that water vapor has corrupted his readings, but you are the expert, not me. Could you re-think this and perhaps help him further?

Pat
