The new Foxboro CFT50 Coriolis mass flow transmitter features patented technology that allows Foxboro mass flow meters to continue operating during two-phase flow. Capable of performing in batch applications starting with empty flow tube conditions, the CFT50 is designed to control all aspects of the Coriolis meter for precise measurement in traditionally difficult flow measurement applications. As demonstrated at the Invensys Showcase Conference, the CFT50 incorporates a patented dual digital processing system to improve meter control throughout all stages of void fraction operation. One processing system controls the meter drive sequence to provide uninterrupted flow tube operation. The second system processes the measurement data from the Coriolis meter, which assures precise fluid measurements. The CFT50 seeks to combine precise and reliable measurement for demanding applications at a low cost of ownership.
