The utility model relates to the technical field of nuclear power maintenance, in particular to a variable-diameter electromagnetic flowmeter for a nuclear sampling system of a nuclear power plant, and a variable-diameter flange A and a variable-diameter flange B are respectively arranged at openings on two sides of a measuring conduit of the electromagnetic flowmeter; the variable-diameter flange A and the variable-diameter flange B are respectively provided with a variable-diameter central taper angle; and fluid in the sampling pipeline flows into the electromagnetic flowmeter from the variable-diameter flange A and flows out of the electromagnetic flowmeter from the variable-diameter flange B. According to the utility model, the variable-diameter flange is connected with the sampling pipeline, so that the lining of the flowmeter is not stressed any more, and the lining is prevented from being deformed or blocked due to overlarge torque. 本实用新型涉及核电维修技术领域，具体公开了一种用于核电厂核取样系统的变径电磁流量计，在电磁流量计的测量导管的两侧开口处分别设有变径法兰A和变
