Annotations languages:

Developed measurement device flow velocity in the test section of the wind tunnel low subsonic speeds, has the advantage over liquid manometers: less inertia, ease of application, clarity of output data, to measure the flow rate fluctuations. The developed device has the potential to become a duplicate anaerobic membrane device existing instruments measuring speed of the aircraft or the main system for small pilotless aircraft.
