Abstract: An Electromagnetic (EM) flowmeter includes pair of coils powered by currents for generating electromagnetic fields, and pair of electrodes for measuring electromotive forces generated by interaction of electromagnetic and flow fields in fluid. To improve measurements during flow distortion, a system configures current in the pair of coils based on a relation between a distance of the EM flowmeter from flow distorting features in the flow pipe and the characteristic length of the EM flowmeter. Further, based on configuration of current in the pair of coils, signals are generated due to electromotive forces and are measured to estimate flow in the pipe.

Abstract: An electromagnetic flowmeter for measuring flow of fluid flowing in a conduit of the electromagnetic flowmeter, wherein the electromagnetic flowmeter includes: a coil attached to an inner surface of the conduit; a movable magnetic ring having segments of magnetic materials that is magnetically coupled with the coil to generate an electromagnetic field to interact with the fluid flowing through the conduit wherein the conduit is provided with an insulating liner. A pair of electrodes mounted on the conduit for measuring potential difference generated by the interaction of the electromagnetic field in the fluid. Wherein the segments of magnetic materials are having varying magnetic properties arranged to have an orderly varying electromagnetic field in the conduit adjustable by rotating the movable magnetic ring. The movable magnetic ring is positioned between the at least one coil and the insulating liner.
