Abstract

A device for determining the composition of a mixture of fluids by spectral absorption, comprises: a radiation source; a detector for detecting radiation that has been attenuated by the mixture; and a device for separating the radiation into a wavelength band corresponding to an absorption band of one of the fluids, a wavelength band corresponding to an absorption band of another of the fluids, and at least one reference wavelength band substantially adjacent to each of the absorption bands, and especially adjacent to each side of the absorption band or group of absorption bands. The device may be used to determine the composition of mixtures of oil, water and gaseous hydrocarbons in oil wells where there is a very large degree of time varying scattering e.g. Rayleigh and Mie scattering due to turbulence.
