Patent ID: 8916815

Claim:
An immersion probe for use in multiphase flow in a pipe comprising: a housing having a first end and second end; one or more optical conduits adapted to carry infrared radiation from a first radiation source at the first end; one or more electromagnetic conduits adapted to carry microwaves both from and to a second radiation source at the first end, wherein a reflectometer containing the second radiation source is used to measure reflected microwaves; a flow gap into which the infrared radiation and the microwaves are transmitted, wherein the flow gap has a predetermined distance between the first end and the second end and is configured to operatively engage the multiphase flow in the pipe; and one or more third optical conduits adapted to: receive at least a portion of the infrared radiation; and transmit at least a portion of the infrared radiation to a first spectrometer for spectral analysis, wherein: the infrared radiation is attenuated through absorption and/or scattering by the multiphase flow in the flow gap; and the multiphase flow is analyzed through the infrared radiation attenuation determined by the first spectrometer and through the reflected microwaves by the reflectometer.
