Abstract
A method for determining the water conductivity and water volume fraction of a multi-component mixture of water and at least one additional liquid or gas in a pipe, the method comprising the following steps: a. electromagnetic phase measurements at least two measurement frequencies are performed between two receiving antennas located at different distances from a sending antenna, b. based on empirically determined constant(s) and the above measurements, the real and imaginary dielectric constants are determined, c. the temperature and pressure are determined d. based on the knowledge of the real and imaginary dielectric constants of the components of the fluid mixture and the result from the above steps a-c, the conductivity of the water and/or the volume fraction of water are determined. An apparatus for performing the method is also disclosed.
