A Pitot-static Tube is a flow velocity meter which is capable of measuring fluid velocities as a localized point (as opposed to an averaged velocity across a larger section). A schematic of a Pitot tube is shown below.
Typical Pitot Static Tube
The Pitot tube yields a pressure measurement which is typically measured with a differential manometer. The fluid velocity can obtained from the pressure value in accordance with incompressible (or compressble) fluid theory.
