| 发明名称 | Method and apparatus for determining phase fractions of multiphase flows | ||
| 摘要 | A multiphase meter for use in the quantification of the individual phase fractions of a multiphase flow has: a resonant cavity through which, in use, a multiphase fluid flows, a signal generator configured to apply electromagnetic energy at a range of frequencies to the cavity, and an enhancing and/or suppressing facility for enhancing and/or suppressing resonant modes of a signal produced resultant to the application of electromagnetic energy to the cavity. | ||

| 主权项 | 1. Apparatus for use in determining individual phase fractions in a multiphase flow, said apparatus comprising: a resonant cavity having a bore through which, in use, a multiphase fluid flows; and one or more probes configured to apply electromagnetic energy at a range of frequencies to said cavity; said apparatus further comprising a suppression or enhancement facility arranged to suppress or enhance at least one resonance mode within said resonant cavity, wherein such suppression or enhancement facility comprises one or more mode conditioners arranged around the circumferential periphery of the bore. | ||
