Straight-run is required in flow meter and pump installations to overcome the swirl, asymmetrical flow profiles, and otherwise unrepeatable flow that is created by elbows, pipe expanders or reducers, valves, dampeners, and other disrupters in the process pipe. In process piping systems, finding or adding a suitable amount of straight-run to accommodate the flow meters, pumps, and other critical components is often impractical or unfeasible, either technically, economically, or both. Flow conditioners, sometimes referred to as flow straighteners, are a practical and cost-effective engineering solution to overcome this lack of available straight-run.
