Abstract
An improved floating sensor for the detection of oil leaks at a water surface is provided wherein a cloth layer is affixed to the outside of a leak detector which, by capillary action, results in a threshold level of oil film thickness below which no alarm sounds and above which an alarm will sound. The invention provides means for the pre-selection of the thickness of oil film which will be detected and eliminates the detection of very thin, inconsequential oil leaks.
