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 distribution station includes a mobile trailer and first and second pumps on the trailer. At least one manifold on the mobile trailer is fluidly connected with the first pump. A plurality of first reels on the mobile trailer are fluidly connected with the at least one manifold. A plurality of first hoses are connected with different ones of the first reels. A plurality of first valves on the mobile trailer are situated between the manifold and respective different ones of the first reels. A plurality of fluid level sensors are associated with different ones of the first hoses. A second reel is not fluidly connected with the manifold, and is fluidly connected with the second pump. A second hose is connected with the second reel that has a manual pump handle, and a controller is configured to individually open and close the valves responsive to the fluid level sensors.

A handheld fluid meter includes a cartridge valve controlling the flow of fluid through the handheld meter. The cartridge valve includes a valve cartridge and a valve stem disposed within the valve cartridge. 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 overmolded stem tip is a compliant material. 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 liquid transfer apparatus and a control method thereof are provided. The liquid transfer apparatus includes a first auxiliary cover, a second auxiliary cover, a transfer tube and a breathing pipe. The first auxiliary cover is configured to cover a container for holding a liquid to be transferred; and the second auxiliary cover is configured to cover a target container. One end of the transfer tube runs through the first auxiliary cover and the other end runs through the second auxiliary cover. One end of the breathing pipe runs through the first auxiliary cover and the other end is configured to introduce nitrogen, or an inert gas, so that the liquid in the container for holding the liquid to be transferred can be transferred to the target container through the transfer tube.

A point-of-sale fuel dispensing system, a pump assembly and a method of dispensing fuel at a point-of-sale. The system includes a market fuel storage tank, pump assembly, fuel conduit, separation unit, numerous enriched fuel product tanks and a controller. The separation unit may selectively receive at least a portion of market fuel and convert it into an octane-rich fuel component and a cetane-rich fuel component that may be subsequently dispensed to a vehicle being fueled, where a fuel grade selection and retail payment of a fuel containing the octane-rich or cetane-rich fuel components is provided to the vehicle based on user input at the customer interface.
