Abstract
The invention is an oil-water detection device for monitoring the presence of water in a container. The device consists of a probe having two thin strips of sheeting within a fiberglass circuit board for sensing the presence of water in a container and generating a signal dependent on the presence of water, a divide counter and Stamp II micro-processor and an accessory communications link connected to the micro-processor. A power supply is also provided. The detection device can differentiate between oil and water and will not be activated merely by the presence of oil on the water.
