A device, essentially a tube set parallel to the direction of fluid-stream movement and attached to a manometer, used to measure the total pressure of the fluid stream.
A small, L-shaped tube which, when inserted vertically into a flowing fluid with its open end facing upstream, measures the total pressure of the fluid and hence, indirectly, the velocity of its flow.
