  • Methods and apparatus for estimating on-line water conductivity of multiphase mixtures
    Publication number: 20030011386
    Abstract: A method and apparatus is disclosed for estimating brine water conductivity in a multiphase mixture of brine water and other substances by combining measured mixture permittivity and conductivity with a known or derived relationship between brine water conductivity and brine water permittivity. The mixture permittivity and conductivity are measured using an open-ended coaxial probe or other means at microwave frequencies. A number of applications for the brine water conductivity estimate are disclosed including making salinity corrections of a dual energy flow meter.
