FLOW CONDITIONER PROFILE PLATE FOR MORE ACCURATE MEASUREMENT OF FLUID FLOW

摘要

The present invention relates to a profile plate for inducing pseudo-fully developed in fluid flowing under turbulent flow conditions in a pipeline of circular cross-section. The plate is comprised of a circular plate body having a center, an upstream face, and a downstream face. The body includes a central array of through bores having a porosity (P1) of from about 3.0 to about 5.0%. A second array of through bores are centered on the locus of a second circle. The porosity (P2) of the second array ranging from about 19.0 to about 21.0%. There is also a third array of through bores having a porosity (P3), where P3=PT-(P1+P2). The through bores are located on the locus of a third circle.
