A flow sensor for compressible fluid comprising a central hub having a total pressure chamber and a static pressure chamber disposed therein. A pair of wings extend radially outward from opposing sides of the total pressure chamber. The wings include a plurality of radially spaced holes oriented to generally face an upstream direction and an internal wing passageway connecting the spaced holes to the total pressure chamber. The sensor also includes a static tube having a tube wall extending outward from the static pressure chamber from a first attached end to a second distal closed end. A generally upstream facing hole and a generally downstream facing hole are disposed on opposing sides of the tube wall intermediate the first and second ends to define a fluid flow passage therethrough. An internal tube passageway connects the flow passage to the static pressure chamber.
