Abstract
An electromagnetic flow meter and method for monitoring the flow of a fluid is provided. In particular, the electromagnetic flow meter and method measure the axial velocity profile of a conducting fluid. The conducting fluid may be a conducting single phase fluid or a conducting continuous phase of a multiphase fluid. The conducting fluid may have a uniform flow profile or a non-uniform flow profile. The electromagnetic flow meter and method measure the axial velocity profile of a conducting fluid by dividing the flow cross section into multiple pixels and determining the axial velocity of the conducting fluid in each pixel. Having derived the axial velocity profile, the electromagnetic flow meter and method may further derive the volumetric flow rate of the conducting fluid. The electromagnetic flow meter and method may be suitable for measuring the axial velocity profile and optionally the volumetric flow rates of each phase of a multiphase fluid.
