APPARATUS FOR SENSING THE PRESENCE OF A CONDUCTIVE LIQUID IN A NON-CONDUCTIVE LIQUID

摘要

An apparatus for sensing the presence of a conductive liquid in one or more containers (12) for containing a substantially non-conductive liquid (20) and discharging the conductive liquid (22) from the one or more containers. The conductive liquid has a higher specific gravity than the non-conductive liquid. The apparatus includes a submersible pump (24) disposed in each one of the one or more containers for pumping liquid from near the bottom of the container. The submersible pump includes an inlet (26) proximate the bottom of the container and an outlet (27). A sensor (29) is provided disposed in each one of the one or more containers for sensing the presence of conductive liquid in the container. The sensing means is disposed proximate the submersible pump. An alarm is operably connected to the sensing means for energizing when the sensing means detects the presence of conductive liquid in at least one of the one or more containers. A pump energizer energizes the pump when the sensing means detects the presence of conductive liquid in the container.
