Abstract

Applications for liquid ultrasonic Custody Transfer flow measurement are traditionally limited to flow ranges within the meter’s performance capability related to the viscosity of the fluid, particularly in the low Reynolds number region where the flow range is across the laminar, transitional and turbulent flow regimes. This paper discusses new methodology by which the flow meter’s performance can be extended into lower ranges of Reynolds numbers for viscous flows while maintaining the close tolerances needed for Custody Transfer measurement applications. The methodology includes the ability to dynamically measure the Reynolds number as well as the fluid’s kinematic viscosity within the laminar to turbulent transition zone.
