pitot tube
Noun
Meaning
measuring instrument consisting of a right-angled tube with an open end that is directed in opposition to the flow of a fluid and used to measure the velocity of fluid flow

Examples
An aircraft Machmeter or electronic flight information system ( EFIS ) can display Mach number derived from stagnation pressure ( pitot tube ) and static pressure.
Furthermore, the pitot tube used to measure airspeed in aircraft can give falsely elevated readings as the pressure builds up inside the tube at high speeds.
In these kinds of measurements, the most practical instrument to use is the pitot tube.
The implementation uses a pitot-static tube which is a pitot tube with two ports, pitot and static, that is normally used in measuring the airspeed of aircraft.
The pitot tube can be inserted through a small hole in the duct with the pitot connected to a U-tube water gauge or some other differential pressure gauge for determining the flow velocity inside the ducted wind tunnel.
The pitot tube static anemometer is on the right.
