Roxar Subsea Wetgas Meter. Spedding, P.; Spence, D. Flow regimes in two-phase gas-liquid flow. The number of gamma rays passing throughout the pipe depends on the composition of the multiphase mixture inside the pipe and therefore indicates the composition of the flow. Understanding of inter-dependency of key sensor parameters by the user helps make a judgement about meter performance and diagnosis of malfunction. Precise volume fraction prediction in oilwatergas multiphase flows by means of gamma-ray attenuation and artificial neural networks using one detector. Multiphase Flow Meters (MPFM) are devices used to measure the individual oil, water and gas flow rates in a multiphase flow. Multiphase Flow Meter. U.S. Patent 6,993,979, 7 February 2006.
