摘要： A flowmeter for measuring the flow of liquid metal in a conduit has a tubular drag body which extends diametrically into the conduit and terminates, with a closed end, within the flowing liquid. The drag body which generates vortexes in the flow, accommodates a magnet that generates a magnetic field in the liquid metal. The potential difference induced in the liquid and being a function of the flow velocity and the frequency of vortex detachment, is sensed by electrodes which are situated within the drag body and, for the purpose of being exposed directly to the liquid, project through respective bores provided in the drag body. The electrodes are bonded gastight to the drag body.
