  • Self-averaging pitot tube probe and method for measuring fluid flow
    Patent number: 4823615
    Abstract: A self-averaging pitot tube probe has an elongated elliptically-shaped body which produces laminar flow of fluid sub-boundary layers around the body. The body includes upstream high pressure sensing ports and a high pressure sensing passageway, and downstream low pressure sensing ports and a low pressure sensing passageway. The low pressure sensing ports open through respective opposite sides of the body upstream from separation points at which the laminar fluid flow sub-boundary layers separate from the body.
