<p>A flow conditioner comprising an apertured circular plate intended to be placed in a conduit in an orientation substantially perpendicular to the axis of the conduit. The apertures are circular and are arranged in a plurality of radially spaced circular arrays around a central aperture. The centre of the central aperture and the centres of the circular arrays coincide with the centre of the circular plate. The apertures in each circular array are equally spaced apart around the centre of the plate, and all the apertures in any one circular array are of substantially the same diameter. The size and number of apertures are such that the impedance to flow presented by the plate increases with the radius on which a given array of apertures is arranged.</p> |
