When selecting a Coriolis mass flow controller size, it is essential to consider the actual flow rates within the pipeline, which may vary from the calculated or design values. It is recommended to choose a Coriolis mass flow controller size that corresponds to a flow rate within the second third of the flow range to achieve optimal performance. As such, the nominal diameter of the Coriolis flow controller can be equal to or less than the nominal diameter of the pipeline.
To address mismatched pipeline diameters to the nominal diameter of the Coriolis flow controller, tapered transitions are the preferred solution. It is advisable to procure tapered transitions independently to minimize pressure loss. It is important to ensure that the central cone angle does not exceed 30º to prevent potential issues.
