Abstract: The invention provides an apparatus, system, and method for detecting a layer of contaminants, such as oil and/or hydrocarbons, on the surface of accumulated water within a confined area that is periodically evacuated by a pump. The detection of contaminant layers may be accomplished through the use of an optical detection system comprising a light source, and a conductive sensor comprising a horizontally-disposed plate and a stilling tube. Dissipation of turbulence and agitation of the accumulated water may be achieved by a stilling tube proximate one or more of the sensors disposed within the stilling tube. Additional sensors may detect high, intermediate, and low levels, and an integrated controller may determine the state of media within the confined area, the system being generally configured to keep the oil or other contaminant within the confined area while continuously and/or periodically pumping water away from the confined area.

Abstract: The invention relates to an apparatus, system, and method for detecting a layer of contaminants, such as hydrocarbons, on the surface of accumulated water within a confined area that is periodically evacuated by a pump. The detection of contaminant layers may be accomplished through the use of an optical detection system comprising a light source, a plate having conductive, capacitive, positional and/or reflective properties, and a capacitive, pressure, optical, or ultrasonic sensor capable of distinguishing between oil and water, with the plate positioned at a distance equal to the desired minimum detectable hydrocarbon layer thickness. Dissipation of turbulence and agitation of the accumulated water may be achieved with a stilling tube. Additional sensors may detect high, intermediate, and low levels, as well as trigger optical sensor measurement. An integrated controller may determine the state of media within the confined area.

Abstract: The present invention relates to methods and systems for implementing a self-test for sump system components using two-way communications between a main controller and each of the system components to check system operation and status. The self-test system is designed to remotely or locally test the installation of field wiring, system functionality and performance of equipment located in an elevator pit, a transformer vault, a transformer moat, a confined space or any other pit/ditch/sump. The benefits of this technology are: 1) ensure proper installation, 2) exercise the system that might otherwise be dormant for years, 3) avoid the costs and risks associated with entering a confined space, and 4) create an easy to implement preventative maintenance program.
