Multi-phase flow, gas-liquid two-phase flow in particular, is of critical importance to industries in Oil and gas sector and power plants. Measurement of multi-phase flow is not easy and the methods currently in use are particularly not very accurate. Uncertainties of unacceptably high order have been reported when conventional single-phase flow-meters such as turbine-meters, mass flow-meters are attempted for multi-phase flow measurement. Extreme variations in viscosity, density and velocity between the phases occur not only across the pipe but also temporarily along the pipe.
A Test Facility was setup at FCRI in 1999 to evaluate performance of the multi-phase flow-meters and aid in the development of two-phase and three-phase flowmeters for different sectors of industry.
