Abstract
A pitot tube having a series of pressure sensing ports on the upstream side of the tube and a second series of pressure sensing openings on the downstream side of the tube. A longitudinal internal wall in the tube forms a pair of chambers, one of which communicates with the upstream ports and the second which communicates with the downstream ports. A plate attached to the end of the tube has diverging passages communicating with the two chambers, the plate forming a flange for connecting a manifold, a transmitter for indicating the flow pressures sensed by the ports, a gauge or the like.
