Abstract
An electromagnetic flowmeter in which the fluid to be metered is conducted through a flow tube in which it intercepts a magnetic field, the voltage induced in the fluid being transferred to electrodes disposed at diametrically opposed points on the tube. In phase noise arising from asymmetry in the main magnetic fluxes as well as noise resulting from leakage magnetic fluxes are both compensated for by a unitary compensation system.
