A method of measuring the composition of an oil and water mixture flowing in a pipeline includes the steps of extracting a sample of the mixture from the pipeline, measuring the speed of sound transmission of the mixture which may be carried out either in the pipeline or in a portion of the extracted sample, separating the water from at least a portion of the extracted sample, measuring the speed of sound transmission of the sample of the mixture having the water separated therefrom, and comparing the determined speed of sound transmission of the mixture and the speed of sound transmission of the sample having water separated therefrom to determine the ratio of oil and water in the mixture.
