Abstract
A drum is filled with two liquids of different densities which are immiscible when combined, such as white phosphorus and water. The drum is positioned on a scale beneath a fill pipe. An actuator lowers the fill pipe into the drum. A quantity of water is injected, followed by a quantity of white phosphorus, followed by a quantity of water to rinse the fill pipe. The fill pipe is raised just out of the liquids and allowed to drip, and then is fully raised to enable the filled drum to be replaced by an empty drum. The white phosphorus is injected at varying flow rates.
