He 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 action 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 offers the best of both worlds; precise and reliable measurement for demanding applications at a low cost of ownership, according to Michael Jost, vice president, measurement and instrumentation division of Invensys. “Coriolis meters provide direct measurement, particularly for difficult to meter materials, such as slurries and homogeneous fluids. The traditional problem has been the impact of entrained air, which can interrupt measurement for tens of seconds and stall or shutdown the flow tube,” says Jost. “With the CFT50, the cost of ownership is significantly reduced, since the meter continues to operate uninterrupted, eliminating loss of production. Maintenance and operating costs can also be reduced since the transmitter can be used in applications with a variety of fluids without re-calibrating,” Jost says.

Allowing multi-variable measurements from the Coriolis meter in Class 1, Division 1 applications, the CFT50 reduces start up time from 20 seconds to five seconds. The new digital transmitter also features low amplitude operation with corresponding reduction in drive power consumption.

Compatible with all Foxboro manufactured CFS10/20 series mass flow meters, the CFT50 is ideally suited for applications such as railcar and tank trunk unloading, pharmaceutical batch applications, pulp and paper coating applications, dairy processes in cheese manufacturing and problematic fluids that foam.
