Abstract
A transfer system for transferring a conductive liquid from a reservoir of the liquid at a first electric potential to receiving equipment which charges the liquid to a second electric potential includes a sump, pump, inlet piping to the sump from the reservoir, and outlet piping from the sump to the receiving equipment. The inlet piping is electrically isolated from the sump. The conductive liquid is introduced into the sump in an interrupted stream to provide electrical isolation between the liquid in the reservoir and the liquid in the sump. The flow of liquid to the sump is controlled by a sensor system to maintain a predetermined level of liquid within the sump.
