US Patent 11261891 Flow conditioning assembly

A flow conditioning assembly comprising an integral elbow flow conditioner and a downstream flow conditioner. The elbow flow conditioner includes a pipe elbow with one or more flow conditioning elements. Each flow conditioning element includes one or more turning guides. Each turning guide is generally circular and radially spaced from one another and an inner surface of the elbow. Spaced vanes maintain the radial spacing of the turning guides. The vanes divide the radial space between the turning guides and pipe elbow into a plurality of flow channels that turn in generally the same direction as the inner surface of the pipe elbow. The downstream flow conditioner comprises a flow conditioning structure within a pipe element. The flow conditioning structure includes one or more flow guides of generally circular form radially spaced from one another and the pipe element. Spaced support vanes maintain the radial spacing of the flow guides.
