Abstract
A flow meter for measuring multi-phase flow and method of use comprising an impeller assembly having a one or more blades in an asymmetric blade configuration on a rotational shaft and one or more sensors to measure partial rotations of the blades. Sensors may obtain impeller rotational information associated with various portions of the flow stream. With this multi-phase fluid flow may be determined from the determined local velocity information, the operation of a fluid-flow system may be enhanced.
