Abstract
A magnetic flowmeter provides a first alternating electrical signal with at least a portion thereof comprising a first electromotive force generated by an electromagnetic interaction between an alternating magnetic field and the velocity of an electrically conductive fluid moving transversely across the alternating magnetic field, wherein the first electromotive force varies as a function of the velocity of the electrically conductive fluid, and a second alternating electrical signal with at least a portion thereof comprising a second electromotive force generated by an electromagnetic induction from the alternating magnetic field and other ambient electromagnetic field, wherein the second electromotive force is independent of the velocity of the electrically conductive fluid, and determines the velocity of the electrically conductive fluid as a function of a phase angle difference between the first and second alternating electrical signals.
