The purpose of this technical report (TR) is to provide a summary of flow conditioning testing performed on turbine meters in liquid hydrocarbons. Initial testing was conducted in water and those findings were included as an addendum to API MPMS Chapter 5.3 in 2009, subsequent testing in hydrocarbon liquids was carried out through July 2016.

Phase II testing focused on operational effects, specifically the relationship of strainer design, strainer basket disturbances, flow conditioning, and their effects on the flow meter deviations in hydrocarbon applications (viscosities, densities, and Reynolds number).
