n: a gas measurement device that consists of a mutiple-ported Pitot tube installed inside a pipe through which gas is flowing;it is installed perpendicular to the flow of gas. The length of the annubar is equal to the diameter of the pipe in which it is installed. An annubar senses the difference between total flowing pressure and static pressure;gas volume is calculated from this difference. See Pitot tube.

a gas flow rate measurement device using Pitot tubes. Common in pipelines.

n: an open-ended tube arranged to face the current of a stream of fluid. It is used in measuring the velocity of a flowing medium.

a small tube used for sensing pressures in a flowing stream.

n: a meter that uses a Pitot tube and a manometer or other differential- pressure mechanism to measure flowing fluids. The difference between the pressure on the Pitot tube and the static pressure is the velocity of the flow, which is directly related to the rate of flow.

n: the speed at which a fluid moves or passes through an object, related to a Pitot tube.
