Abstract
A method for determining the water conductivity of a multi-component mixture of gas and at least one liquid containing water in a pipe, the method comprising the following steps: a. electromagnetic measurements at least two measurement frequencies are performed in a pipe near the pipe wall at a first cross-sectional location where the mixture predominantly contains gas and at a second cross-sectional location where the mixture predominantly contains liquid, b. the temperature of the multi-component mixture is determined, and c. based on an empirically determined relationship between the measurements performed is step a and b and the conductivity of pure water, the conductivity of the water contained in the multi-component mixture is determined. An apparatus for performing the method is also disclosed.
