ABSTRACT:
A radial field electromagnetic flow meter includes a radial magnetic flux generator, a magnetic device surrounded by a fluid passage for fluid to be measured and electrically insulated magnetic poles separately positioned on a center line of the fluid passage, a tubular part surrounding a range including the mutually opposite magnetic poles of the magnet device through the fluid passage, and ribs radially crossing portions of the fluid passage between one end of the magnet device and a portion of the tubular part surrounding the one end of the magnet device, respective surfaces of the tubular portions and the ribs which come into contact with the fluid to be measured being electrically insulated, whereby the magnetic reluctance of the magnetic circuit of the magnet device can be reduced and the sensitivity of the electromagnetic flow meter can be improved.
