Abstract
A detector for an electromagnetic flowmeter provided with a pair of detecting electrodes disposed opposite to each other on the inner surface of a piping, through which fluid, whose flow rate is to be measured, flows, and a magnet forming a magnetic field in the direction perpendicular both to the axis of the piping and to the line connecting the detecting electrodes, in which the magnet has a pair of magnetic poles, which are so formed that the magnetic flux density is greatest in the neighborhood of the position apart from the middle point of the straight line segment connecting the detecting electrodes by 0.3 d in the direction towards each of the detecting electrodes, d being the inner diameter of the piping.
