## Abstract

A flow conditioner includes 1) a single disk comprising an array of holes and having an outer ring of holes, and 2) a section extending longitudinally from an outer circumference of the disk and comprising bores that at least partially follow the contour or pattern of the outer ring of holes.

## Claims

### Claim 1

A flow conditioner, comprising:
a single disk comprising an array of holes and having an outer ring of holes, and
a section extending longitudinally from an outer circumference of the disk and comprising bores that at least partially follow the contour or pattern of the outer ring of holes.

### Claim 2 (depends on 1)

A flow conditioner according to claim 1, wherein a portion of an outer ring of holes or apertures is bored along the section.

### Claim 3 (depends on 1)

A flow conditioner according to claim 1, where the flow conditioner is machined as a single integral piece.

### Claim 4 (depends on 1)

A flow conditioner according to claim 1, wherein the section comprises a plurality of bores, each bore extending from an outer hole and at least partially following a circumference of the outer hole.

### Claim 5 (depends on 1)

A flow conditioner according to claim 1, wherein between holes of the outer ring of holes, along a surface of the disk, there are opposing sharp or pointed corners.

### Claim 6 (depends on 5)

A flow conditioner according to claim 5, further comprising flat sections extending longitudinally along the section extending longitudinally between bores.

### Claim 7 (depends on 1)

A flow conditioner according to claim 1, wherein a length of the section extending longitudinally is about 0.15 D to about 2 D, wherein D is the inside pipe diameter of the pipe in which the flow conditioner is installed.

### Claim 8 (depends on 1)

A flow conditioner according to claim 1, wherein a diameter of the flow conditioner is about 2 to about 4 inches.

### Claim 9 (depends on 1)

A pipe assembly for flow measurement, comprising:
a fluid flow pipe;
a flow conditioner according to claim 1 disposed within said fluid flow pipe in an orientation substantially perpendicular to an axis of said fluid flow pipe.

### Claim 10 (depends on 1)

A fluid flow measurement system, comprising:
a fluid flow pipe;
a flow conditioner according to claim 1 disposed within said fluid flow pipe in an orientation substantially perpendicular to an axis of said fluid flow pipe; and
a flow meter downstream of the flow conditioner.

### Claim 11 (depends on 10)

A fluid flow measurement system according to claim 10, wherein the fluid flow pipe has an inside diameter D, and wherein there is 8 D between the flow conditioner and the flow meter and a minimum of 5 D upstream of the flow conditioner.
