Abstract:
1. A differential pressure fluid flow meter element for insertion between the connecting flanges of conduit sections of a fluid carrying conduit, comprising, a flat circular plate having a parametric edge, a center and upstream and downstream facing surfaces which are perpendicular to a fluid flow in the conduit sections, the upstream and downstream facing surfaces each having a fluid engaging portion for disposition within the fluid carrying conduit, the flat circular plate further including a solid center region which includes the center of the flat circular plate, a plurality of apertures formed in the fluid engaging portions of the circular plate and which are eccentrically disposed with respect to the solid center region of the plate, the apertures permitting fluid carried by the conduit to flow through the circular plate, at least one opening in at least one of the fluid engaging portions in the solid center region, at least one pressure port disposed in the parametric edge of the plate, and at least one conduit extending to the solid center region carried by the plate in fluid communication with the at least one opening in at least one of the fluid engaging portions and the at least one pressure port.
