I just wanted to share this cutaway of Daren's design.  If air is flowing left to right then the pressure going into the left tube should be higher than in the right tube.  And if the air flows the other way then vice versa.  I have some differential pressure sensors that just arrived so I'm going to try to see how sensitive they are by testing this idea below.
