Dear Rob,
As I understand there are many air flow meters in the market. However the size of
the normal flow meters or sensors are too big for your application to install a number
of probes on the mask head.
We can suggest to try the hot wire annemometer or microphones to evaluate the
flow profiles. This will be however very difficult job and a certain amount of technical
development will be necessary.

: I am looking for a method to visualise or measure the air flow within a gasmask (on a artificial head).
: Introducing a number of probes on the head is allowed, but they have to be small enough to be
: incorporated. Also, the probes must be accurate enough to measure typical air flows during different
: breathing cycles (in between 20 - 100 liter/minute).
