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.

A refuelling system suitable for use with an overwing fuelled aircraft comprising: (b) a stored fuel grade identification means for identifying the fuel grade stored in the fuel storage vessel and available type(s) of delivery of the fuel to the aircraft; (d) an aircraft fuel grade identification means being attached to, or forming part of, an overwing fuelled aircraft, wherein said aircraft fuel grade identification means represents the fuel grade requirement of the aircraft and is readable from the exterior of the aircraft; (g) a transmission and receiving system which enables information regarding the fuel grade that had previously been supplied to the aircraft having the aircraft registration number inputted into the computer interface and the type of delivery of fuel which may be used by said aircraft to be retrieved from a remote database; (i) an automated cross-check system which is configured to retrieve the fuel grades identified by the fuel identification means in (b), retrieve the fuel grade identified in (d) from the hand-held device, retrieve the type(s) of delivery of fuel identified by the fuel identification means in (b) and by the system of element (g), and the previous fuel grade supplied to the aircraft identified by the system in element (g) which can generate a positive response signal if all of the fuel grades identified are compatible with each other and the type(s) of delivery of fuel to the aircraft are compatible.

A system includes a processor configured to wirelessly instruct fuel dispensation initiation over a direct wireless connection between a vehicle and a refueling truck, responsive to a wireless request made by the refueling truck, the request including a valid token and a refueling truck MAC ID with which the wireless connection is established.

In one aspect, data characterizing a session during which fuel is to be dispensed from a fuel dispenser can be received from the fuel dispenser and by a client device of a user of the fuel dispenser. A fuel dispensing parameter characterizing an operational parameter of the fuel dispenser can be received at a field of a graphical interface displayed on the client device. A token characterizing a credential associated with the user for initializing the dispensing of the fuel during the session can be determined. An initialization of the dispensing of the fuel from the fuel dispenser can be authorized based on the determined token and the received fuel dispensing parameter.

Methods and systems provide for detecting tampering of a fuel dispenser. Power is applied to a valve coil of a fuel dispenser. The valve coil is part of a control valve configured to accomplish a gradated fuel flow of the fuel dispenser. Current flowing through the valve coil is measured in response to the power being applied to the valve coil. The current measurements are compared with predetermined criteria and tampering with the valve coil is determined if the current measurements are sufficiently different than expected.

Fluid storage and dispensing systems and processes involving various structures methods for fluid storage and dispensing, including, pre-connect verification couplings that are usefully employed with fluid storage and dispensing packages to ensure proper coupling and avoid fluid contamination issues, empty detect systems (e.g., monitoring pressure of dispensed liquid medium to detect pressure droop conditions) useable with fluid storage and dispensing packages incorporating liners that are pressure-compressed in the fluid dispensing operation, ergonomically enhanced structures for facilitating removal of a dispense connector from a capped vessel, cap integrity assurance systems for preventing misuse of vessel caps, and keycoding systems for ensuring coupling of proper dispense assemblies and vessels. Fluid storage and dispensing systems achieve zero or near-zero headspace character, and prevent or ameliorate solubilization effects in liquid dispensing from liners in overpack vessels.
