Abstract
The flow rate of molten aluminum through a trough is measured by damming off the trough and diverting the flow through the measuring tube of a magnetic flow meter having a diameter, and located at a level in the trough to create a head of molten aluminum sufficient to produce a flow through the tube which is within the operating range of the meter. The apparatus includes a pair of spaced apart dam members forming a cavity therebetween which is transversed by the measuring tube. The magnet of the flow meter is located in the cavity preferably in a housing through which cooling air is circulated. The electrodes are made of an electrically conductive material which is resistant to corrosion by the molten aluminum, preferably, titanium diboride. Spring biased tapered connections seal the measuring tube with the dam members which have peripheral seals to keep molten aluminum out of the cavity.
