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.

A sensing device used to measure total pressures in a fluid stream. It was invented by a French physicist, Henri Pitot, in the 1700's ( 0301)

A small ell shaped tube which can be attached to a pressure gauge or other measuring device to measure the velocity head of water discharging from a nozzle.

A standard velocity meter, an L-shaped device consisting of two concentric tubes, when inserted vertically into an air stream, one tube measures total pressure, the other static pressure. When connected across a manometer, the difference between these pressures, the velocity pressure, is indicated. The velocity pressure can be used to compute the velocity of the air stream.

a sensor to measure fluid velocity by generating a pressure that is the difference between the total static pressure and the dynamic pressure

measuring instrument used to measure the velocity of fluid flow

measuring instrument consisting of a combined Pitot tube and static tube that measures total and static pressure; used in aircraft to measure airspeed

a device for measuring the speed of an aircraft through the air

an L shaped tube which is also able to measure fluid flow

a tube designed to permit measuring two relative pressures which are indicative of speed

differential pressure device that utilises the conversion of kinetic energy into pressure energy, ideal for point measurement, may be cantilever, or static.

a tube with a pressure sensor at one end, open on the other. The open end is placed facing into the air going past an airplane. Combined with another pressure sensor, the difference between the two can be used to gauge the airspeed of the plane. Temperature and perhaps humidity (not sure about humidity) enter into the equation somehow.

device for measuring velocity of air in a duct.

A tube mounted on the outside of the airplane that is exposed to the relative wind and provides ram air pressure to the airspeed indicator.

A sensing unit inserted into the gas stream to measure gas velocity based on a differential between the total pressure and the static pressure

A hollow tube that connects the area beneath the regulator diaphragm with the vena contracta area of gas flow. The pitot tube causes the diaphragm to sense a pressure lower than that which exists downstream of the regulator, and thus allows the regulator to open more for any given change in downstream pressure. The result is increased regulator accuracy.

An instrument for measuring the relative speed of a fluid. It consists of a concentric pipe arrangement in which the inner pipe is open at one end and the outer pipe is perforated and closed at both ends. Each pipe is connected to a manometer. The unit is operated with the open end pointing upstream, so that the inner pipe measures the total pressure and the outer pipe measures the static pressure. The difference between these pressures, the dynamic pressure, is proportional to the square of the fluid speed.

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). Pylon A sign, marking the corner of the racing course. May be a tripod like structure or a simple pole with an oil drum on top of it.

A Pitot tube is a measuring instrument used to measure fluid flow, and more specifically, used to determine airspeed on aircraft. The Pitot tube is named after its inventor, Henri Pitot, and was modified to its modern form by Henry Darcy.

A metering device consisting of a double-walled tube with a short rightangle bend. The periphery of the tube has several holes through which static pressure is measured. The bend end of the tube has a hole through which total pressure is measured when pointed upstream in a moving gas stream.

(Or Pitot-static tube.) A pressure anemometer consisting of two concentric tubes that are oriented parallel to the flow. The inner tube is open at the upstream end to sense the total pressure, while the outer tube is closed with a rounded contour and has a ring of small static pressure ports a short distance downstream. Each tube is connected to a manometer and the difference between the two pressures, the dynamic pressure, is proportional to the square of the fluid speed.

Device which measures the fluid flow difference between static and dynamic pressure and is used in fluid systems to monitor operating characteristic and fluid velocity.

A curved tube having an opening that is inserted into a stream of water and to which a pressure gauge is attached that indicates the discharge pressure of the stream; instrument containing a Bourdon tube that is inserted into a stream of water to measure the velocity pressure of the stream; the gauge reads in units of pounds per square inch (psi) or kilopascals (kPa).
