Abstract
According to the present invention there is provided a flow conditioner for insertion into a pipe of predetermined diameter conveying a fluid flow. The conditioner comprises a plate arranged perpendicular to the flow and having apertures which are located so as to distribute the flow radially in an approximation to the flow distribution in a fully developed flow, and a plurality of vanes distributed such that the normal to each vane is perpendicular to the direction of flow.

A flow conditioner for insertion into a pipe of predetermined diameter conveying a fluid flow, the conditioner comprising:
- a plate arranged perpendicular to the flow and defining apertures which are located so as to distribute the flow radially in approximation to flow distribution of a fully developed flow;
- and
- a plurality of vanes distributed such that the normal to each vane is perpendicular to the direction of flow;
- wherein each vane extends radially from the pipe wall to a point spaced from the pipe axis.
A flow conditioner for insertion into a pipe of predetermined diameter conveying a fluid flow, the conditioner comprising:
- a plate arranged perpendicular to the flow and defining apertures which are located so as to distribute the flow radially in approximation to flow distribution of a fully developed flow;
- and
- a plurality of vanes distributed such that the normal to each vane is perpendicular to the direction of flow;
- wherein additional vanes are located downstream of the plate and extend axially away from the plate adjacent the wall of the pipe.
A flow conditioner for insertion into a pipe of predetermined diameter conveying a fluid flow, the flow conditioner comprising:
- a plate arranged perpendicular to a fluid flow direction and having apertures located to distribute the fluid flow radially to approximate a fully developed fluid flow;
- and
- a plurality of vanes extending upstream from the plate and distributed such that the normal to each vane is perpendicular to the fluid flow direction;
- wherein the vanes extend from the plate such that the apertures of the plate are unobstructed.
A flow conditioner for insertion into a pipe of predetermined diameter conveying a fluid flow, the flow conditioner comprising:
- a plate arranged perpendicular to a fluid flow direction and having apertures located to distribute the fluid flow radially to approximate a fully developed fluid flow;
