ABSTRACT:
Process and apparatus for accurately measuring the volume or mass flow rate of each component phase of a two-phase mixture. In particular, mixtures of crude oil and natural gas in changing proportions and having fluctuating differential flow velocities are encountered at the wellhead. The volume rate of flow of the oil and gas components are separately determined by temporarily isolating successive fractions of the mixture, determining the component proportions and the volume flow rate of each successive fraction and calculating the product thereof. Mass flow rate may be determined by incorporating the densities of the components into the calculation. Total throughput may be calculated by summing the products of the component proportion and the flow rate for all successive fractions.
