Problem.
The flow is small and you are working in a condensing humidity environment. A simple flapper vane with a magnet on it is going to rock and roll with every movement and then get all wet and stop. I wouldn't like to promise it would work all dive let alone all week.

My first guess as the instrumentation man would be to use the cooling effect of dropping from IP to ambient and put a little bead thermistor in the gas path.
Audio would be another way, a tiny mike just next to it but they don't like the damp and if they are sealed they don't like the pressure.

My HUD is still stalled under lots of work...
