ABSTRACT:
An electromagnetic flowmeter generates a magnetic filed perpendicular to a ring earth electrode contacting fluid at an end portion of a measuring tube and a point electrode attached to a lower portion of the measuring tube so as to measure a flow rate without depending on a fluid level. The electromagnetic flowmeter comprises magnetic field generation means for generating the magnetic field in the measuring tube to be perpendicular to an axial direction of the measuring tube such that electromotive force generated in fluid is not influenced by the fluid level, flow rate output means for calculating a flow rate of fluid flowing in the measuring tube based on a potential developed in the fluid by said magnetic filed generated by the magnetic field generation means so as to output the calculated flow rate, and display means for displaying the flow rate calculated by the flow rate calculation means.
