A dispensing unit having a circulation system for circulating a fluid in the dispensing unit is provided. The circulation system comprises, a circulation circuit, and a mechanism configured to circulate the fluid in the circulation circuit. By circulating the fluid, the fluid is counteracted from crystallizing. A method for circulating a fluid in a dispensing unit is also provided.

The present application discloses a method, device and system for automatic oiling of a long-distance transport vehicle. The method provided by the present application includes: obtaining, by a transport planning system at a network side, vehicle status information, transport mission information and highway port information of the vehicle before the long-distance transport vehicle starts from a highway port of departure; generating a transport plan according to the vehicle status information, the transport mission information and the highway port information, wherein the transport plan comprises at least one highway port to be stopped at, cargo quantity to be loaded at each highway port to be stopped at and oil mass to be filled at each highway port to be stopped at; and sending the transport plan to the vehicle.

A fuel dispenser comprises fuel flow piping defining a flow path from a source of fuel toward a fueling nozzle. A plurality of fuel handling components are disposed along the fuel flow piping. Control electronics are in operative communication with the fluid handling components. The fuel dispenser includes network circuitry operative to create a wireless peer to peer network with an adjacent vehicle. After creation of such network, the control electronics receive transaction information from the vehicle in electronic form via the network circuitry, and cause at least one function of the fuel dispenser to be controlled for a transaction based on the transaction information.

A fuel management method for long term stationary truck use is provided. This method includes a truck with at least a first saddle tank or a second saddle tank integral to the truck. Each saddle tank has a fuel level sensor to measure the fuel level. A fuel trailer provides supplemental fuel, and a fuel pump downstream of the fuel trailer and upstream of the truck pressurizes the fuel from the fuel trailer. The method includes supplying fuel to local users from saddle tanks, activating the fuel pump when the fuel level of both the saddle tanks is less than a first predetermined threshold, thereby transferring fuel from the fuel trailer to the first saddle tank and the second saddle tank, deactivating the fuel pump when the fuel level of either the saddle tanks is greater than a second predetermined threshold.

Various systems, devices, and methods are provided for facilitating communication between a forecourt controller and a fuel dispenser. In certain aspects, a fuel controller translator is provided for translating commands transmitted between the forecourt controller and the fuel dispenser. For example, where the forecourt controller transmits commands that are compatible with the payment terminal, but not with the fuel controller, the fuel controller translator can translate the commands received from the forecourt controller into a format compatible with the fuel controller. Conversely, the fuel controller translator can translate commands received from the fuel controller into a format that is compatible with the forecourt controller.

A method for receiving a plurality of captures of a vehicle from a plurality of locations. Calculating a plurality of signatures of the vehicle, each respectfully associated with a corresponding capture from the plurality of captures. Associating the plurality of signatures resulting in a single signature and utilizing the single signature for identifying the vehicle.

A refueling vehicle may have a front fuel dispensing module with at least one or more hoses for dispensing fuel product from the fuel tank to an external tank. The front fuel dispensing module is located between the cab and the fuel tank containing the fuel product.
