A fluid management system includes an authentication device and a fluid dispensing meter, and the fluid dispensing meter includes a processor and a memory. The authentication device is configured to provide user-identification data to the processor. The processor is configured to recall approved user identities from the memory, to compare the approved user identities to the user-identification data received from the authenticator, and to control a trigger control mechanism between the activated state and the deactivated state based on the comparison of the user-identification data and the approved user identities.

A fluid management controller includes a processor, a wireless interface, and a memory. The wireless interface is configured to communicate between the processor and one or more fluid management components. The processor is configured to authorize control of the one or more fluid management components over the wireless interface. The memory is encoded with instructions that, when executed by the processor, cause the processor to provide dispense authorizations to the one or more fluid management components and record fluid dispense information from the one or more fluid management components in the memory.

A system ensures the correct type of fuel is dispensed in an aircraft while removing the introduction of human error in the refueling process. The system includes an RFID tag disposed at one or more aircraft that electronically stores data such as engine type, engine hours, fuel type, tail number, and pilot/subscriber data for the aircraft on which the RFID tag is disposed. An RFID reader is disposed at or near a fuel dispensing mechanism, such as a fuel truck or tank. A signal indicative of fuel type is emitted from the RFID tag to the RFID reader. RFID tags on aircraft that are enrolled in the system's subscription service enable aircraft to be recognized by a module operating the fuel dispensing mechanism. Based on a comparison performed by the module, authorization to begin fueling is either permitted or declined.

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.

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.

A fluid management system includes a fluid management controller and a fluid dispenser. The controller authorizes control of the one or more fluid management components over a wireless interface. A dispensing meter can be activated by an authentication device. The fluid meter includes a cartridge valve with a valve cartridge and a valve stem. The cartridge valve guides the valve stem and provides the only sealing surface for the dynamic seals and control seal disposed on the valve stem. The handheld meter dispenses through a nozzle, which includes an overmolded stem tip that generates a laminar fluid flow as the fluid exits the nozzle. The handheld fluid meter includes circuitry configured to invert the orientation of a visual output provided by a display of the handheld fluid meter to facilitate installation of the handheld fluid meter for use in an oil bar application.

A fuel dispensing system includes a fuel tank, a pump that pumps fuel from the fuel tank, and a fuel sentry controlling pumping of the fuel from the fuel tank. The fuel sentry includes a processor, storage storing configuration data, a communication module, and memory operatively coupled to the processor, the storage, and the communication module. The memory includes instructions that, when executed by the processor, cause the processor to: receive, from an external device and via the communication module, a request to perform a fuel dispensing operation from the at least one fuel tank, determine, based on the configuration data stored in the storage, whether a user of the external device is authorized to perform the fuel dispensing operation from the at least one fuel tank, and in response to determining that that user is authorized to perform the fuel dispensing operation from the at least one fuel tank, transmit power to the pump from a power source to allow the user to pump fuel.

The application relates to a fueling station for a fuel generator having a fuel generator reservoir, the fueling station comprising: a station reservoir (11) for storing at least one reactant for fuel generation; a fueling interface (14) configured to engage with the fuel generator reservoir and dispense the at least one reactant to the fuel generator reservoir; and a controller (18) configured to: receive a parameter indicative of an intended use of the fuel generator; and control the fueling interface to dispense the at least one reactant in accordance with the parameter.

A fluid nozzle includes a housing, a poppet configured to move within the housing, and a contact sensor disposed in the housing and configured to sense a position of the poppet. A contact sensor may include an actuation rod configured to move in response to contact with the poppet, an actuation rod spring configured to apply a biasing force to the actuation rod, a push rod, a rolling member disposed between the actuation rod and the push rod, and a switch actuated via movement of the push rod. In a connected position of the poppet, the actuation rod may push the rolling member, the rolling member may push the push rod, and the push rod may activate the switch to indicate a connection.

A radio frequency identification (RFID) dispenser that includes low cost electronic components that can read and write to the tag of a refill cartridge. In one embodiment, the reader utilizes a multi band pass filter to convert the radio frequency identification into a digital signal that is processed by a controller to perform a dispensing function representative to the code of the tag. In another embodiment, the controller utilizes an internal comparator to convert the radio frequency identification into a digital signal that is processed by a controller to perform a dispensing function representative to the code of the tag. The dispenser in both embodiments also includes a pair of transistors that write to the RFID tag of the refill cartridge. A dispenser according to the invention also includes the capability to read and/or write to tags upon cartridges employed by the dispenser, and augmenting the operation of the dispenser as a function thereof. Additionally, a dispenser of variable size is presented that is adaptable, through adjustable partitions or a telescoping cup, to receive and maintain cartridges of various sizes.
