Truncated balanced realization of a stable non-minimal state-space system
Michael Tombs,Ian Postlethwaite +1 more
TL;DR: In this article, the authors present a numerically reliable algorithm to compute the balanced realization of a stable state-space system that may be arbitrarily close to being unobservable and/or uncontrollable.
Patent
Multi-phase coriolis flowmeter
TL;DR: In this article, a flowmeter is disclosed, which includes a vibratable flow tube, and a driver connected to the flow tube that is operable to impart motion to the Flow tube.
Patent
Wet gas measurement
Manus Henry,Michael Tombs +1 more
TL;DR: In this article, a multi-phase process fluid is passed through a vibratable flow tube, and a first apparent property of the process fluid based on the motion of the flow tube is determined.
Journal ArticleDOI
Two-phase flow metering of heavy oil using a Coriolis mass flow meter: A case study
Manus Henry,Michael Tombs,Mihaela Duta,Feibiao Zhou,Ronaldo Mercado,Frank Kenyery,Joseph Shen,Martin Morles,Carlos Garcia,Robbie Langansan +9 more
TL;DR: The use of Coriolis mass flow metering for two-phase (gas/liquid) flow is an emerging theme of both academic research and industrial application as discussed by the authors, and the key issues are maintaining flow-tube operation and modelling and correcting for the errors induced in the mass flow and density measurements.
Patent
Multiphase coriolis flowmeter
TL;DR: In this paper, a flowmeter includes a vibratable flowtube, and a driver connected to the flowtube that is operable to impart motion to the Flowtube and generate a sensor signal.
