In a method and apparatus for metering water content in an oil-water system by determining sonic velocities in the flowing oil-water mixture, and thereafter determining flow rate to provide individual oil and water rates which may then be integrated to provide oil and water volume of flow, the improvement comprising self-calibrating for salt content of the system water by measuring the speed of sound in the water phase only and utilizing the measured value in determinations of the system water cut.
