Abstract:
1. A method for measuring the component fractions of a water continuous fluid flow also containing gas and/or oil, comprising the steps of: repeatedly measuring the electrical properties of a cross section of the fluid, and detecting time periods during which the fluid has low gas content based on the measured electrical properties of the fluid, wherein the detected time periods correspond to an absence of gas bubbles in the fluid, during said periods of low gas content, measuring the density of the fluid in the fluid flow proximate to the cross-section of the fluid where the electrical properties are measured, wherein the density measurements are performed in at least one of said periods of low gas content and a fluid density is calculated based on the measured densities over one or more of said periods, wherein the density is measured using gamma equipment and a high sampling rate receiver and wherein the density is calculated from sampled gamma readings received by the receiver during a chosen number of the time sequences identified by low gas content.
