Abstract
A flow conditioner comprising a perforated plate with a central hole and four or more circular paths, which are arranged radially from the central hole and concentrically with one another, wherein holes are arranged on these concentric circular paths, characterized in that a preponderate number of holes of an intermediate circular path have a greater hole diameter than a preponderate number of holes of the innermost and a preponderate number of holes of the outermost circular paths.

A flow conditioner comprising a perforated plate with a cylindrical central hole and four or more circular paths that are arranged radially from the central hole and concentrically with one another, wherein cylindrical holes are arranged on the concentric circular paths, wherein a preponderant number of holes on an intermediate circular path have a greater hole diameter than a preponderant number of holes on a radially innermost circular path and a preponderant number of holes on a radially outermost circular path, wherein a radius of a hole on the innermost circular path is 2% to 10% greater than a radius of the central hole, wherein a radius of a hole on a second circular path following the innermost circular path is 2% to 10% greater than the radius of a hole on the innermost circular path, wherein the radius of a hole on the second circular path is 2% to 10% greater than a radius of a hole on a third circular path following the second circular path.
A flow measuring device, comprising:
- a flow conditioner including a perforated plate with a central hole and four or more circular paths that are arranged radially from the central hole and concentrically with one another, wherein holes are arranged on the concentric circular paths, wherein a preponderant number of holes on an intermediate circular path have a greater hole diameter than a preponderant number of holes on a radially innermost circular path and a preponderant number of holes on a radially outermost circular path, wherein a radius of a hole on the innermost circular path is 2% to 10% greater than a radius of the central hole, wherein a radius of a hole on a second circular path following the innermost circular path is 2% to 10% greater than the radius of a hole in the innermost circular path, wherein the radius of a hole on the second circular path is 2% to 10% greater than a radius of a hole of a third circular path following the second circular path.
A flow conditioner, comprising:
- a circular plate having a plurality of cylindrical holes,
- wherein one of the plurality of holes is a central hole disposed in the center of the plate,
- wherein the remaining holes are disposed in at least four groups:
- a first group disposed uniformly along a first circular path concentric with the central hole, the holes of the first group having a uniform size such that a radius of a hole in the first group is 2% to 10% greater than a radius of the central hole,
- a second group disposed uniformly along a second circular path concentric with the central hole, the second circular path having a diameter greater than a diameter of the first circular path, the holes of the second group having a uniform size such that a radius of a hole in the second group is 2% to 10% greater than the radius of a hole in the first group,
- a third group disposed uniformly along a third circular path concentric with the central hole, the third circular path having a diameter greater than the diameter of the second circular path, the holes of the third group having a uniform size such that the radius of a second group hole is 2% to 10% greater than a radius of a third group hole, and
- at least a fourth group disposed uniformly along a fourth circular path concentric with the central hole, the fourth circular path having a diameter greater than the diameter of the third circular path, the holes of the fourth group having a uniform size such that the radius of a second group hole is 30% to 60% greater than a radius of a fourth group hole.
