A fleet fueling system may be implemented with controllers electronically interfacing with fuel dispensers at dispensing stations and communicating via a wide area network with one or more computing device implementing multiple subsystems. Hardware components and subsystems may be configured to avoid operating errors and provide end-to-end functionality, including one or more of: avoiding damage to movable readers that can collect information about assets positioned at fuel dispensing stations, selectively authorizing fuel to be dispensed based on the types and amount of fuel those assets are authorized to receive, quickly and reliably entering information about assets, providing analytics relating to fuel usage per asset, predicting future fuel needs at each of multiple fuel dispensing sites and scheduling fuel deliveries based on predicted needs, and detecting or correcting operating errors in the system.

Embodiments herein relate to a mobile fuel distribution station including a plurality of fuel tanks, one or more fuel pumps arranged to distribute fuel from said fuel tanks to users, a central fuel refill arrangement for refilling of one or more of said plurality of fuel tanks, and a fuel leakage prevention system, a central fuel refill arrangement and a fuel leakage prevention system arranged to prevent leakage from the central fuel refill arrangement, and from any of the plurality of fuel tanks. Other embodiments herein relate to a method and a system for predicting points of time for refilling fuel in one or more such mobile fuel distribution stations.

A variable temperature control assembly for a water dispenser, using a variable water temperature selector, that delivers water to the consumer at the temperature requested on the variable temperature selector by calculating the required ratio of hot water, cold water and ambient water needed to deliver water at the temperature requested.

Aspects of the disclosure relate to fluid injection systems, apparatus, methods, and associated components thereof that include flexible hoses for wellhead sites. In one implementation, a fluid injection system for wellhead sites includes a pump, a pump manifold, and a flexible hose coupled between the pump and the pump manifold. The flexible hose includes a first end coupled to the pump and a second end coupled to the pump manifold. The first end of the flexible hose includes a first end fitting coupled to the pump, and the first end fitting is oriented at an angle relative to a horizontal plane. The second end of the flexible hose includes a second end fitting coupled to the pump manifold, and the second end fitting is oriented vertically and perpendicularly to the horizontal plane.

A fluid supply system adapted for vacuum and pressure cycling of fluid, including a transfer vessel adapted to supply a process canister with fluid drawn from a bulk canister under a vacuum, wherein delivery of fluid from the transfer vessel to the process canister is accomplished with positive pressure. A method is also disclosed of delivering fluid, including drawing fluid under vacuum from a bulk canister and pressurizing the transfer vessel to effect dispensing of the fluid into a process canister for delivery to a location of use.

The invention relates to a tank filling system having a protective cap and having a pouring spout. The protective cap has an end position wherein it partially covers the pouring spout, and wherein the protective cap has an opened position wherein it is removable from the pouring spout into a removed position. The pouring spout includes at least one valve, wherein the valve has a venting position and a closed valve position. In the venting position, the valve frees at least one passage for a fluid. In the closed valve position, the valve closes the passage. In the end position of the protective cap, the valve is in the closed valve position. During the adjustment of the protective cap from the end position into the opened position, the valve is forcibly adjusted at least temporarily into the venting position.

A transfer pump includes a drive module having electronic components and a fluid module not including electronic components. The drive module provides motive power to a pump of the fluid module to power pumping by the fluid module. A control module is configured to monitor operation of the transfer pump and control pumping by the transfer pump. The control module is configured to receive dosing commands from a user interface, recall a dosing parameter based on the dosing command, and cause the drive module to operate the fluid module based on the dosing parameter to cause the transfer pump to output a set volume of material.

A computer device, located inside a vehicle, may include logic configured to detect a re-fueling trigger for the vehicle and may send a fuel bid request to a fuel auction system for fuel prices within a geographic area of the vehicle. The computer device may receive information relating to a fuel price reverse auction generated by the fuel auction system; generate a user interface that displays the received information that includes variable discount fuel prices associated with a plurality of fueling stations within the geographic area; receive information relating to the results of the fuel price reverse auction from the fuel auction system; display the results of the fuel price reverse auction in the generated user interface; and receive selection of a fueling station via the user interface based on the results.
