Abstract
Apparatus for batching a metal melt such as steel from a pressure tapping furnace in which a level measuring device is provided for measuring the melt level in the tapping spout and using that level to calculate a signal for terminating the batching which is dependent on the integral of melt flow, and the rate of change of melt flow so as to take in to account the double draining which occurs after the termination of batching is initiated.
