Abstract: If acceptable upstream flow conditions for different classes of flow meter are to be produced within short installation lengths a flow conditioner must be viewed as an essential component of any metering installation. Such devices can be classified in terms of their mode of operation into two distinct types, turbulent mixing or vortex action devices. It is demonstrated that a low loss, device combining features of both types of unit can be produced capable of yielding downstream flow conditions close to fully developed, in terms of both time mean flow and turbulence intensity structure, within an overall length of approximately 6 pipe diameters.
