ABSTRACT:
A pair of electrodes and a pair of magnetic poles are mounted to a resin-made conduit body with each of those parts partly exposed to the lumen. The magnetic poles are formed by an electrically conductive material and serve also as ground electrodes by being connected to ground. The magnetic poles serving also as the ground electrodes are positioned in the same plane as signal electrodes with a result that the distance on the axis of the conduit between the signal electrodes and the ground electrodes is fixed, more precisely, the distance is zero, so that the zero point of the electromagnetic flowmeter is stabilized. The magnetic poles, mounted to the conduit body, are separated from the yokes on which coils are wound, and both the magnetic poles and the yokes are detachable.
