A method and apparatus for metering water content in an oil-water system by measuring sonic velocity in a flowing oil-water mixture, thereafter to determine flow rate to provide individual oil and water rates which may then be integrated to provide oil and water volume of flow. The apparatus functions to provide continual readout of oil and water data by deriving bi-directional speed of sound through the moving medium with subsequent frequency difference processing to derive sonic velocity, flow rate measurement and subsequent integral data output. |
