Abstract: A fuel moisturization sensor system is disclosed. The fuel moisturization sensor system includes a first light source configured for emitting light through a fuel and moisture flow path at a first wavelength, wherein the first wavelength is at least partially absorbable by the moisture when in a vapor phase and substantially not absorbable by the fuel, and a second light source configured for emitting light through the fuel and moisture flow path at a second wavelength, wherein the second wavelength is preferentially scattered by moisture when in a liquid phase and substantially not absorbed by the fuel or by the moisture when in a vapor phase, a detector system configured to detect light transmitted through the flow path at the first and second wavelengths and to generate a first data signal corresponding to the transmission at the first wavelength and a second data signal corresponding to the transmission at the second wavelength.

Abstract: Determination of steam quality by passing one or more laser beams through steam in a steam chamber and directly determining a total number of vapor molecules and a total number of water molecules based on absorption of radiation in the one or more laser beams by the water vapor phase and the liquid water phase in the steam. Specific volumes of water vapor phase and liquid water phase in the steam using the total numbers of water vapor and liquid water molecules are determined and the quality of the steam is calculated based on the specific volumes of the water vapor phase and the liquid water phase in steam. One embodiment comprises a narrow linewidth laser for measuring steam quality and another embodiment comprises multiple broadband lasers for measuring steam quality.
