ABSTRACT:
An electromagnetic flowmeter has a ferromagnetic main casing and a nonmagnetic flow speed measuring tube passing through the main casing. A pair of electrodes are diametrically disposed in the measuring tube and insulated from it. Magnetic flux generators are disposed in the main casing and arranged perpendicularly to the measuring tube and the central line of the electrodes. Magnetic flux induction elements are formed in the main casing for reducing and extending a magnetic flux density in the measuring tube.
