Recent years have seen significant advances in Coriolis flowtube technology Arguably, however, it is advances in transmitter technology that will ultimately prove more significant in providing users with the desired level of measurement performance and robustness. The key to transmitter enhancement is new digital technology, enabling improvements in flowtube control, signal processing, and measurement quality. The Sensor Validation Research Group at the University of Oxford, in partnership with Invensys Foxboro, has been developing Coriolis transmitter technology for many years. The latest Oxford prototype is the basis for the new Foxboro CFT50 Coriolis transmitter product. Key features include digital synthesis of the drive waveforms, and maintaining operation during two-phase or aerated flow.
