Pitot Tubes & Probes
A pitot probe, also known as a pitot tube, is a device used to measure fluid flow velocity for various needs, such as:
- To measure liquid, air and gas flow speeds and rates in industrial applications
- To ascertain the airspeed, Mach number, and altitude of an aircraft
- To calculate the water speed of a boat
A basic pitot probe is made up of a tube containing fluid that points directly into the fluid flow, measuring the pressure.
A static probe is the most common pitot probe used on an aircraft and instead contains a diaphragm that measures dynamic pressure. These can be mounted on the side of the fuselage or a boom on the nose or leading edge of a wing or fin and are connected directly to the airspeed indicator in the cockpit.
