Claims16
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;
- and
- an 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, and
- wherein 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.
