Abstract

To satisfy the need for a gasoline leak sensor with faster detection of fuel leaks and a much faster recovery after detection, an optical approach has been developed. This approach uses differences in refractive indices to discriminate gasoline from air or water. The sensor is designed to detect an 1/8-inch layer of gasoline, even when it is floating on water, but it will not trigger on a gasoline layer less than 1/32 inch thick. The basic sensor design is described including techniques used to stabilize the output over a range of required operating conditions.
