Abstract

According to one embodiment, an electromagnetic flowmeter includes a measurement pipe, a first coil, a second coil, core members, and an electrode. An object to be measured flows through the measurement pipe. The first coil is provided radially outside the measurement pipe, the first coil generates a magnetic field in the measurement pipe. The second coil is provided radially outside the measurement pipe and forms a pair with the first coil, the second coil generates the magnetic field in the measurement pipe. The core members are provided in an inner circumference of the first coil and an inner circumference of the second coil in a radial direction of the measurement pipe. The electrode is provided in the measurement pipe, the electrode detects induced electromotive force generated from a flow of the object to be measured through the measurement pipe. The inner circumference of the first coil, the inner circumference of the second coil, and an outer diameter of the core member have shapes such that the core members can be provided in the inner circumference of the first coil and the inner circumference of the second coil.
