Abstract:
An apparatus for measuring flow in a pipe, comprising:a first pipe having a first straight section for receiving fluid flow and a converging pipe structure positioned downstream of the first straight section for disturbing the fluid flow therethrough; a flow condition apparatus mounted within a second pipe coupled to the first pipe and positioned downstream of the converging pipe structure, the flow conditioning apparatus including: a ring for reducing the effective diameter of the second pipe; a centrally disposed hub; a plurality of angled members attached to the hub on a first end portion, the angled members having a second end portion extending radially outward from the hub; the second end portion of the angled members being attached to the ring such that the plurality of angled members cause the disturbed fluid to swirl within the pipe, wherein a combination of the fluid swirling within the pipe and the reduced effective diameter of the pipe creates a symmetric flow profile; and an ultrasonic flow measurement device mounted to the pipe to measure flow characteristics of the symmetric flow profile.
