Invensys receives two new patents.INVENSYS RECEIVES TWO NEW PATENTS. Invensys, Foxboro, Massachusetts, USA has received two additional patents for the core technology of the company's Foxboro CFT CFT complement fixation test; see under fixation. CFT complement fixation test. 50 Digital Coriolis mass flowmeter See flow meter. . U.S. patent numbers 6,754,594 and 6,758,102 apply to the Digital Coriolis flowmeter and its ability to correct for two-phase flow In fluid mechanics, two-phase flow occurs in a system containing gas and liquid with a meniscus separating the two phases. Historically, probably the most commonly-studied cases of two-phase flow are in large-scale power systems. . The new patents relate to new signal processing See DSP. techniques used to provide useful measurements of both mass flow and density and the operational aspects of keeping the Coriolis meter running stably in single-phase or two-phase flow conditions, and dynamic transitions between these flow conditions. The Digital Coriolis flowmeter technologies were developed through a collaborative program between the Foxboro Measurements and Instruments Division of Invensys Process Systems and Oxford University, United Kingdom. |
