Crossover protection system graphical user interfaces, crossover protection systems that display graphical user interfaces, and methods for pairing tank delivery connectors with product delivery vehicle systems are provided. A tank delivery connector reads a tank tag with a tank tag reader, and transmits a tank tag indicator associated with the tank tag with network interface hardware. An electronic control unit receives the tank tag indicator with network interface hardware, determines a distribution tank fuel type associated with a distribution tank based on the tank tag indicator, determines that the tank delivery connector is associated with a tank compartment of a product delivery vehicle based on the tank tag indicator, and displays a graphical user interface on the display. The graphical user interface includes a tank delivery connector graphic displayed proximate a tank compartment graphic to indicate that the tank delivery connector is associated with the first tank compartment.

Methods and systems are provided for identifying misfueling in a vehicle fuel tank when an incorrect fuel type is provided. In one example, a method may include routing fuel vapors from a vehicle fuel tank to a fuel vapor storage canister and monitoring a temperature profile of a fuel system canister during a refueling operation, and when an actual temperature profile is below an expected temperature profile, misfueling is identified. Further, responsive to an indication of misfueling, further addition of fuel is disabled during the refueling event.

Methods and systems are provided for identifying misfueling of a vehicle fuel tank with a fuel that is not of a correct type for the vehicle being refueled. In one example, and method may include routing fuel vapors from a vehicle fuel tank to a fuel vapor storage canister during a refueling operation, and responsive to an indication of misfueling, where the indication of misfueling includes a monitored pressure in the fuel tank below a misfueling pressure threshold, and where the misfueling pressure threshold is adjusted as a function of expected pressure in the tank during refueling, actively terminating the refueling event. In this way, addition of an incorrect fuel type to a vehicle fuel tank may be indicated prior to completion of refueling, which may thus alert a vehicle operator of the misfueling, and which may prevent further complications arising from operating the vehicle with an incorrect fuel type.

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.

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.

A fluid detection flange for a product transfer verification system includes a coupling frame having an opening defining a fluid path configured to be fluidly coupled with a fluid source. A sensor in the flange measures at least one characteristic of a fluid in the opening and the sensed characteristic is used to determine the type of fluid pending for transfer. In operation, if the pending fluid is the same type as is meant to be placed in a destination container then the transfer is allowed.

Hydrocarbon condensate detection and control. The hydrocarbon condensate detection and control system includes detecting hydrocarbon in an aqueous mixture and controlling the flow of the aqueous mixture based on the hydrocarbon content of the aqueous mixture.

An aircraft is disclosed including a fuel tank, and a refuelling system configured to feed fuel into the fuel tank. The refuelling system includes a sensor. The sensor is configured to measure a composition of fuel in the refuelling system before it is fed into the fuel tank, and the sensor is further configured to generate an output based on the measured composition.

A product delivery system includes a product transport vehicle having at least a plurality of tank compartments, internal valves, control valves, fluid property sensors, temperature sensors, overfill sensors, pressure sensors, a system controller, and a memory module. The product delivery system may be operable to communicatively connect with the loading system at a loading station, a fleet management system, or a cloud system to obtain information, such as the amount of liquid product to be loaded into a tank compartment. The product delivery system may be operable to compare the volumes of the tank compartments with the amounts of liquid product to be loaded at a loading station and maintain the internal valve or control valve in a locked state or transition the internal valve or control valve to an unlocked state based on the comparison. Other comparisons based on liquid type or distribution tank volume can also be made.
