Title
(EN) APPARATUS FOR SENSING THE PRESENCE OF A CONDUCTIVE LIQUID IN A NON-CONDUCTIVE LIQUID
(FR) APPAREIL POUR DETECTER LA PRESENCE D'UN LIQUIDE CONDUCTEUR DANS UN LIQUIDE NON CONDUCTEUR
Abstract
(EN)
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.

Appareil servant à détecter la présence d'un liquide conducteur dans un ou plusieurs conteneurs (12) contenant un liquide essentiellement non conducteur (20) et à décharger le liquide conducteur (22) d'un ou plusieurs conteneurs. Le liquide conducteur possède une masse volumique plus grande que le liquide non conducteur. L'appareil comprend une pompe submersible (24) se trouvant dans chacun des conteneurs pour pomper le liquide situé près du fond du conteneur. La pompe submersible comprend une entrée (26) près du fond du conteneur, ainsi qu'une sortie (27). Un détecteur (29) est placé dans un ou plusieurs des conteneurs pour détecter la présence d'un liquide conducteur dans le conteneur. Le détecteur est placé près de la pompe submersible. Une alarme reliée au détecteur est activée lorsque ce dernier détecte la présence d'un liquide conducteur dans au moins un des conteneurs. Un activateur de la pompe excite cette dernière lorsque le détecteur détecte la présence d'un liquide conducteur dans le conteneur.
