A plug flow converting pipeline and method for creating a plug flow condition of a fluid in a pipeline or similar conduit so that a desired measurement of the fluid may be conducted. In one embodiment, the converting pipeline includes a section of pipeline with an elongated flow channel disposed therein. The flow channel acts to reduce the amount of energy stored in the fluid fibers thereby enabling them to re-flocculate and form a plug flow condition. While a sufficient length of straight pipeline may enable the fibers to re-flocculate, the flow channel provides a 'calming effect' thereby enabling the overall length of straight pipeline to be reduced. In another embodiment, the pipeline includes a T-shaped transition piece attached to the pipeline designed to create a chaotic flow condition which quickly transforms into a plug flow condition, thereby requiring a shorter length of straight pipeline.
