Two-phase flow effects are governed by an increased decoupling ratio or a decreased Velocity of Sound (VOS) in the process fluid due to entrained gas, aeration, or the presence of liquid in gas. Following best practices regarding installation and meter selection can prevent or minimize measurement errors associated with two-phase flow effects. Tip For more details regarding the effects of two-phase flow on Coriolis meters, or performance expectations in these applications, see the Entrained Gas Handling in Micro Motion Coriolis white paper and any additional resources available at www.emerson.com/ flowmeasurement. Performance influences during two-phase flow conditions Optimal meter performance during two-phase flow conditions is primarily governed by meter selection, flow regime, and fluid properties. Sample magnitudes of the effect are provided in the white paper referenced previously. The information in the
