The invention relates to an electromagnetic flowmeter capable of avoiding fluid particle noise. Each electrode in a measuring pipe of the electromagnetic flowmeter is formed by cascading a section of solid electrode and a section of liquid electrode, and the liquid electrode parts make contact with a to-be-measured liquid in the measuring pipe. Each liquid electrode part is composed of one or more holes which extend to the corresponding solid electrode from the inner wall face of the measuring tube and filled with conductive liquid. The conductive liquid of the liquid electrodes can be liquid formed by pouring and staying the to-be-measured liquid. In this way, when the to-be-measured liquid flows in the measuring pipe, particles do not make contact with the solid electrodes directly, and noise caused by the particles is almost not produced on signals output by the solid electrodes. Meanwhile, inductive electric potential produced by the to-be-measured liquid in the measuring pipe can be transmitted to the solid electrodes through the liquid electrodes. A signal measuring unit of the electromagnetic flowmeter is connected to the solid electrodes to measure an inductive electric potential signal generated by flowing of the to-be-measured liquid.
