Abstract:
A flow sensor for compressible fluid having a fluid flow from an upstream direction toward a downstream direction, the flow sensor comprising:a smoothly contoured central hub having a total pressure chamber and a static pressure chamber disposed therein; a pair of wings extending radially outward from opposing sides of the total pressure chamber of the hub, the wings including a plurality of radially spaced holes oriented to generally face the upstream direction and an internal wing passageway connecting the spaced holes to the total pressure chamber; and a static tube having, a tube wall extending radially outward from the static pressure chamber of the hub from a first attached end to a second distal closed end, a generally upstream facing hole and a generally downstream facing hole disposed on opposing sides of the tube wall intermediate the first and second ends to define a fluid flow passage therethrough, and an internal tube passageway connecting the flow passage to the static pressure chamber.
