Abstract
A signal generator for reducing the influence of fluctuations in flow rate distribution in a fluid passing through the flow tube of an electromagnetic flowmeter, which fluid intercepts a magnetic field therein to induce an emf which is transferred to the meter electrodes, thereby yielding a signal as a function of flow rate. To this end, the tube is provided with auxiliary electrodes disposed at arbitrary positions at which the potentials developed thereon are equal to each other when the existing flow rate distribution is symmetrical with respect to the flow tube axis, the auxiliary electrodes being interconnected.
