A flow conditioner includes a single disk having a first side and a second side; an outer ring comprising a plurality of holes, wherein the holes extend from the outer ring to the first side of the disk; at least one inner ring recessed from the outer ring, the at least one inner ring comprising a plurality of holes, wherein the holes extend from the at least one inner ring to the first side of the disk; and a central hole recessed from the at least one inner ring. The plurality of holes in the outer ring and in the at least one inner ring provide fluid passages of unequal length from a first side of the flow conditioner to a second side of the flow conditioner.

1. A flow conditioner, comprising: a single disk having a first side and a second side;a central hole that opens on a first side of the disk;at least one inner ring comprising a concentric ring of a plurality of holes, wherein the holes define fluid passages from the at least one inner ring to the first side of said disk; andan outer ring comprising a concentric ring of a plurality of holes, wherein the holes define fluid passages from the outer ring to the first side of said disk;wherein 1) a diameter of the central hole is greater than the diameters of the plurality of holes of the at least one inner ring, and 2) the diameters of the plurality of holes of the at least one inner ring are greater than the diameters of the plurality of holes of the outer ring, andwherein 1) the central hole defines a fluid passage having a length which is less than the length of the fluid passages of the plurality of holes of the at least one inner ring, and 2) the length of the fluid passages of the plurality of holes of the at least one inner ring is less than the length of the fluid passages of the outer ring,wherein the at least one inner ring is in a stepped, recessed configuration from the outer ring. 2. A flow conditioner according to claim 1, wherein the plurality of holes of the outer ring and the plurality of holes of the at least one inner ring each comprise circular holes. 3. A flow conditioner according to claim 1, wherein the central hole is recessed from said at least one inner ring. 4. A flow conditioner according to claim 1, wherein the at least one inner ring comprises two or more stepped, recessed concentric rings, each concentric ring comprising a plurality of holes. 5. A flow conditioner according to claim 1, further comprising a flange connection on the first side of said disk. 6. A flow conditioner according to claim 1, further comprising a flange connection on the second side of said disk. 7. A flow conditioner according to claim 1, further comprising a coating or plating composition comprising nickel or a nickel-phosphorous alloy. 8. A flow conditioner according to claim 1, further comprising an outer ring and at least one inner ring on both sides of the flow conditioner. 9. A method of designing a flow conditioner, comprising: determining fluid dynamics of a pipe into which a flow conditioner is to be installed; andcalculating a configuration for a plurality of holes of the at least one inner ring and the outer ring of a flow conditioner according to claim 1. 10. A method of designing according to claim 9, wherein a length of a fluid passage defined by each hole (x) is a function of the radius (r) from a center of the pipe. 11. A method according to claim 9, wherein the length of a fluid passage is calculated by the following formula: D=C*Tan−1(VT/Vx)wherein D is the depth of the flow conditioner holes, VT is the tangential velocity of a fluid in the pipe, Vx is the axial velocity of the fluid in the pipe, and C is a coefficient that corrects for fluid viscosity, density, wall roughness and the swirl reduction factor. 12. A pipe assembly for flow measurement, comprising: a fluid flow pipe;at least one 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. 13. A pipe assembly according to claim 12, wherein the outer ring and at least one inner ring are on an upstream side of the at least one flow conditioner. 14. A pipe assembly according to claim 12, wherein the outer ring and at least one inner ring are on a downstream side of the at least one flow conditioner. 15. A pipe assembly according to claim 12, wherein an outer ring and at least one inner ring are on both sides of the flow conditioner. 16. A fluid flow measurement system, comprising: a fluid flow pipe;at least one 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; anda flow meter downstream of the flow conditioner. 17. A flow conditioner according to claim 1, wherein said stepped, recessed configuration is from a first planar surface to a second planar surface. 18. A flow conditioner according to claim 1, wherein said stepped, recessed configuration is on the first side of said disk, the second side of said disk being flat. 19. A flow conditioner, comprising: a single disk with a central hole, said central hole having a first diameter and defining a first fluid passage;at least one inner ring comprising a concentric ring of a first plurality of holes, said first plurality of holes having a second diameter less than the first diameter and defining second fluid passages;an outer ring comprising a concentric ring of a second plurality of holes, said second plurality of holes having a third diameter less that the second diameter and defining third fluid passages,wherein the at least one inner ring is in a stepped, recessed configuration from the outer ring, andwherein the greater the diameters of the respective holes, the shorter the length of the respective fluid passages. 20. A flow conditioner according to claim 19, wherein said stepped, recessed configuration is on a first side of said disk, a second side of said disk being flat.
