Patent ID: 8733180

Claim:
A fluid flow tool for use in making differential measurements of flow attributes, comprising: an airfoil structure having a flat surface that defines a high-pressure side of said airfoil structure and a shaped surface that defines a low-pressure side of said airfoil structure, said flat surface and said shaped surface meeting at a leading edge of said airfoil structure and a trailing edge of said airfoil structure; a support arm coupled to said airfoil structure and coupled to an exterior wall of a conduit wherein said flat surface and said shaped surface face opposing walls of the conduit; at least one measurement port formed in said flat surface of said airfoil structure between said leading edge and said trailing edge; a first manifold formed in said airfoil structure and in fluid communication with each said measurement port so-formed in said flat surface, said first manifold extending through said airfoil structure and said support arm to terminate and be accessible at the exterior wall of the conduit; at least one measurement port formed in said shaped surface of said airfoil structure between said leading edge and said trailing edge; and a second manifold formed in said airfoil structure and in fluid communication with each said measurement port so-formed in said shaped surface, said second manifold extending through said airfoil structure and said support arm to terminate and be accessible at the exterior wall of the conduit.
