Abstract
An apparatus and method of measuring free water, also known as undissolved water, in hydrocarbon fuel. A housing defines a chamber and is adapted to receive a fluorescein impregnated filter pad in the chamber between a UV light source and a light sensor. The filter pad is exposed to the fuel causing the free water to react with the fluorescein and is then placed within the chamber between the light source and sensor. The UV light strikes one side surface of the filter pad and excites the reacted fluorescein thereby causing light emitted from the UV light reacted fluorescein filter pad opposite side surface to strike the light sensor. An output from the light sensor is proportional to the fluorescein on the filter pad which reacted with free water and is used for providing an output value representative of the free water present in the hydrocarbon fuel.
