A method and apparatus for obtaining a measure of the relative contents of a petroleum stream containing oil and water together with a third fluid which is either gas or surfactant. The method transmits microwave energy into the petroleum stream, receives microwave energy transmitted through the petroleum stream, stores predetermined values of attenuation and phase difference between the transmitted and received microwave energy representative of the stream containing 100% oil, 100% water and 100% of sais third fluid, generating a map utilizing reference points representative of those 100% cases, determining a measurement point P within the map and deriving therefrom a signal representative of the oil/water ratio or other desired ratio. <IMAGE> |
