Device which measures fluid flow velocity, typically around an aircraft or boat
Aircraft use pitot tubes to measure airspeed. This example, from an Airbus A380, combines a pitot tube (right) with a static port and an angle-of-attack vane (left). Air-flow is right to left.Types of pitot tubesA pitot-static tube connected to a manometerPitot tube on Kamov Ka-26 helicopterPitot tubes on a Formula One carLocation of pitot tubes on a Boeing 777
A pitot tube (/ˈpiːtoʊ/PEE-toh; also pitot probe) measures fluid flow velocity. It was invented by a French engineer, Henri Pitot, in the early 18th century,[1] and was modified to its modern form in the mid-19th century by a French scientist, Henry Darcy.[2] It is widely used to determine the airspeed of aircraft;[3] the water speed of boats; and the flow velocity of liquids, air, and gases in industry.
