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.
