Abstract:

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 c-ray densitometer. With an error of ±5% in component fraction measurements, this instrument is appropriate for testing and calibrating other meters.
