A method and system of dispensing a fuel from a fuel tank to a recipient fuel tank. The method includes scanning a tag by a scanner from a smart device, wherein the smart device also comprises a communications processor, recording an initial inventory level of the fuel in the fuel tank, estimating a density of the fuel, opening a valve to dispense a predetermined amount of the fuel, and recording a final inventory level after the dispensing the fuel, upon estimating that the density of the fuel is within a predetermined range, and shutting the valve and communicating to relevant personnel about the difference in fuel density, upon estimating that the density is outside of the predetermined range.

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.

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.

Dispensing device including a dispensing conduit configured to convey a liquid between a supply source and a tank, the dispensing conduit including a closure system having an open state and a closed state, an analysis system including an analysis chamber and an odor sensor, a central electronic system capable of placing the closure system in the open state if an odor signal delivered by the odor sensor matches the odor of the liquid intended to fill the tank, and placing the closure system in the closed state if an odor signal delivered by the odor sensor does not match the odor of the liquid intended to fill the tank.

Some embodiments of the present invention provide Apparatus (100) comprising: a fluid inlet (105IN) for receiving fluid from a fluid source, a fluid outlet (105OUT) and a conduit (110) disposed therebetween; fluid inspection means (152) for inspecting a fluid within the conduit (110), the inspection means (152) being configured to provide an output indicative of a type of fluid in the conduit (110); valve means (120) operable selectively to prevent or allow flow of fluid through the conduit (110) from the fluid inlet (105IN) to the fluid outlet (105OUT); and control means (150) configured automatically to cause the valve means (120) to prevent or allow flow of fluid through the conduit (110) in dependence on the output of the fluid inspection means (152) and permitted fluid information, the permitted fluid information being information indicative of a type of fluid that is to be permitted to flow through the conduit (110), the apparatus (100) comprising an electrical generator (140) configured to generate electrical power to charge a charge storage device in response to flow of fluid through the apparatus (100) during an operation in which fluid flows from the fluid inlet (105IN) to the fluid outlet (105OUT) via the conduit (110), the charge storage device being arranged to provide a supply of electrical power for the apparatus.

Hydrocarbon condensate detection and control. The hydrocarbon condensate detection and control system includes detecting hydrocarbon in an aqueous mixture by sensing fluorescence, turbidity, and color of the aqueous mixture and controlling the flow of the aqueous mixture based on the hydrocarbon content of the aqueous mixture.

A refueling system for motor vehicles, that includes a motor vehicle with a first communication interface and with a control unit, as well as a refueling installation, a second communication interface, which has a communication connection to the first communication interface for the transmission of data, as well as a tank with a fuel. The refueling installation has a sensor device, which is equipped to determine a fuel material property of the fuel of the refueling installation and to transmit it to the motor vehicle, so that the control unit of the motor vehicle controls a vehicle component on the basis of the determined fuel material property.

A product delivery vehicle system includes a product delivery vehicle with at least one tank compartment. The system includes an internal valve fluidly coupled to the tank compartment, a control valve, and an air system comprising a main air valve and a solenoid valve fluidly coupled to the main air valve and to the internal valve. The solenoid valve is operable to open and close the internal valve. The system includes an electronic control unit communicatively coupled to the control valve, the main air valve, and the solenoid valve. The system includes a tank tag reader operable to read a tank tag and transmit a tank tag indicator associated with the tank tag, the tank tag indicator indicative of a stored liquid type in a distribution tank. The electronic control unit may maintain the internal valve closed and the control valve locked when a product type mismatch is detected.

Dispensing device including a dispensing conduit configured to convey a liquid between a supply source and a tank, the dispensing conduit including a closure system having an open state and a closed state, an analysis system including an analysis chamber and an odor sensor, a central electronic system capable of placing the closure system in the open state if an odor signal delivered by the odor sensor matches the odor of the liquid intended to fill the tank, and placing the closure system in the closed state if an odor signal delivered by the odor sensor does not match the odor of the liquid intended to fill the tank.
