For Pitot Tube we have terms and definitions in 5 topics. The topics are Airfoil, Aviation, Boiler, Natural Gas and Sanitation.

Pitot Tube (Airfoil)

An L-shaped, open tube, one end connected to a pressure measuring device, the other end placed in a flow with the opening facing the wind. Can be used to measure the total pressure of a flow (stagnation pressure). In conjunction with a static pressure measurement the flow velocity can be calculated, if the density of the fluid is known. A device, which combines both pressure measurements is a pitot-static tube (at least in Germany also called a Prandtl-tube).
Named after a Frenchman, Henri Pitot (1695-1771).

Pitot Tube (Aviation)

More accurately but less popularly used, Pitot-Static Tube, a small tube most often mounted on the outward leading edge of an airplane wing (out of the propeller stream) that measures the impact pressure of the air it meets in flight, working in conjuction with a closed, perforated, coaxial tube that measures the static pressure. The difference in pressures is calibrated as airspeed by a panel instrument. Named after French scientist Henri Pitot (1695-1771).

Pitot Tube (Boiler)

An instrument which will register total pressure and static pressure in a gas stream, used to determine its velocity.

Pitot Tube (Natural Gas)

A small device that can be inserted into a pipe to measure the flow of a liquid or gas. This device is composed of two tubes arranged in such a manner that will allow the measurement of both the velocity and static pressures of the flowing liquid or gas. The difference in these pressures is a function of the flow within the pipe.

Pitot Tube (Sanitation)

A device for measuring the velocity of flowing fluid by using the velocity head of the stream as an index of velocity. It consists essentially of an orifice held to point upstream and connected with a tube in which the impact pressure due to velocity head may be observed and measured. It also may be constructed with an upstream and downstream orifice, or with an orifice pointing upstream to measure the velocity head or pressure and piezometer holes in a coaxial tube to measure the static head or pressure, in which case the difference in pressure is the index of velocity.
