Abstract
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.

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.
Apparatus for use in determining individual phase fractions in a multiphase flow, said apparatus comprising:
- a resonant cavity 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 comprising one or more electrically conductive structures extending around an arc of the cavity to suppress or enhance at least one resonance mode within said resonant cavity.
Apparatus for use in determining individual phase fractions in a multiphase flow, said apparatus comprising:
- a resonant cavity;
- a wall within the resonant cavity defining a through bore though 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 comprising one or more electrically conductive structures embedded in the wall to suppress or enhance at least one resonance mode within said resonant cavity.
