In offshore oil field development, a more accurate and economic measurement method is necessary to monitor flow rates of both phases of the mixture produced from the oil wells at the bottom of the sea. In this study, a turbine flow meter is employed on the basis of a novel concept to measure simultaneously volumetric flow rates of both phases of an air-water mixture. Although a conventional turbine flow meter is used to measure single-phase volumetric flow rates by reading rotational rotor speed, pressure drop across the meter as well as the rotation speed is measured, and these measured values are satisfactorily correlated with the volumetric flow ratio of the air to the whole fluid and the total volumetric flow rate. Using the correlation functions obtained, the volumetric flow rates of both phases are iteratively evaluated on the premise that the liquid density is known. Evaluated flow rates show good agreement with the measured values, confirming the applicability of this method to the oil field.
