Abstract: An optical fluid sensor (OFS) is disclosed that includes a body defining a chamber and having one or more apertures to allow a fluid to enter the chamber, a light source optically coupled to the chamber and configured to emit light into the chamber, and a detector optically coupled to the chamber and configured to receive light from the chamber. The light source may emit IR, visible, and UV light into the chamber, and the detector may measure an intensity of one or more wavelengths of IR or visible light received by the detector. When fluid is disposed within the chamber, the light emitted by the light source may pass into and through the fluid disposed in the chamber before being received by the detector. A crossover protection system is also disclosed that includes an OFS for determining a transported liquid type.

Abstract: A crossover protection system including a product transport vehicle having a tank compartment for containing a liquid product, a fluid property sensor positioned to contact liquid product stored in the tank compartment, a system controller, and a valve coupled to the tank compartment. The valve regulates a flow of liquid product from the tank compartment and has a normally locked state. The system controller may compare a received transported liquid type signal from the fuel property sensor indicative of the type of liquid product in the tank compartment and compare the type of liquid product to a stored liquid product type. If the two types match, the crossover protection controller transitions the valve to an unlocked state to allow the liquid product to unload from the tank compartment. If the two types do not match, the crossover protection controller will disable the valve from transitioning to the unlocked state.
