Abstract
An electromagnetic flowmeter includes a measuring pipe and a cylindrical case. The measuring pipe has a pair of pipe connecting flanges at both ends of its outer surface. The cylindrical case surrounds the outer surface of the measuring pipe so as to cover a pair of excitation coils arranged on the outer surface of the measuring pipe, and is welded and fixed to ring-like collar portions extending from inner surfaces of the flanges. The thickness of the ring-like collar portions to which the case is welded and fixed is set to be larger than that of the case.
