Abstract
A method and an apparatus for determining at least one property of a multiphase fluid. The method includes the steps of directing the multiphase fluid through a first flow passage, monitoring the multiphase fluid as it passes through the first flow passage to obtain a first signal representing a first flow characteristic of the multiphase fluid as a function of time, directing the multiphase fluid through a second flow passage, monitoring the multiphase fluid as it passes through the second flow passage to obtain a second signal representing a second flow characteristic of the multiphase fluid as a function of time, and then determining the property of the multiphase fluid by comparing the first signal and the second signal with a set of calibration maps. The second flow passage has a geometry different from the first flow passage which relates either to the cross section of the two flow passages or to the direction in which the multiphase fluid passes through the flow passages relative to gravity.
