Abstract
The present invention relates to a system for measuring conductivity in a multiphase fluid flow comprising a fraction of water, the system comprising a measuring section including means for emitting electromagnetic signals into a pipe containing said flow within at least one chosen frequency range and means for detecting resonant frequencies within said range. The measuring section comprising features for providing at least two resonanct frequencies within said at least one frequency range, the system also comprising means for based on at least a first resonant frequency and a first Q-factor related to the corresponding resonance peak as well as the Q-factor of a second resonance peak, calculating the conductivity of the water in said flow.
