Pi·tot tube

 (pē′tō, pē-tō′)
n.
A device, essentially a tube set parallel to the direction of fluid-stream movement and attached to a manometer, used to measure the total pressure of the fluid stream.

[After Henri Pitot (1695-1771), French physicist.]

Pitot tube

(ˈpiːtəʊ)
n
1. (Aeronautics) a small tube placed in a fluid with its open end upstream and the other end connected to a manometer. It measures the total pressure of the fluid
2. (General Physics) short for Pitot-static tube, esp one fitted to an aircraft
[C18: named after its inventor, Henri Pitot (1695–1771), French physicist]

Pi′tot tube`


n.
(often l.c.) an instrument for measuring fluid velocity, consisting of a narrow tube, one end of which is open and faces upstream, the other end being connected to a manometer.
[1880–85; after Henri Pitot (1695–1771), French physicist, who invented it]
