摘要
System for measuring the composition of a multiphase fluid flow in a pipe, the multiphase flow containing a mixture of gas and liquid. The system comprising a first and a second sensor arrangement, wherein each sensor arrangement is adapted to measuring electrical characteristics (i.e. impedance) of the flow at a predetermined rate. The system also including an analysis unit being adapted to monitor the measured electrical characteristics from said first and second sensor arrangement and to detect occurrences of time periods involving a predetermined relationship between the measured characteristics, and during these periods assuming a liquid rich phase and calculating the composition based on the electrical characteristics.
