Two-phase flow component fraction measurement using gamma-ray attenuation technique

Multiphase flow meters as the potential alternatives to separation and metering techniques have been in rapid development since 1980s. Before its field operation, the instrument should be calibrated in a standard test-facility. In spite of the known medium and large scale facilities all over the world, we developed a laboratory scale instrument for component fraction measurements. It has a two-phase flow homogenizer loop with the clamp-on potential of the meters to provide a regime independent measurement. It is capable of delivering a complete homogenization by γ-ray densitometer. With an error of ±5% in component fraction measurements, this instrument is appropriate for testing and calibrating other meters.
