Pumping and measuring apparatus for fluid metals comprising an electromagnetic pump which operates in two modes; first, an idling mode in which the pump operates at one rate of flow and continually circulates fluid metal out of a reservoir, through an opening in a conduit and back to the reservoir; second, a delivery mode in which the pump operates at a higher rate of flow and circulates fluid as in the idling mode, and further raises the fluid metal to a higher opening in the conduit for delivery therethrough. A timing control for selectively adjusting the durations of each mode as well as the time intervals between modes allows high accuracy of measurements of quantities of fluid metal delivered. |
