A float probe configured to regulate fluid flow into a fluid container is disclosed. The float probe comprises an upper assembly having one or more outlets, a plurality of rods extending from the upper assembly to a lower assembly and a float assembly disposed between the upper assembly and the lower assembly. A first distal end of the rods is coupled to the upper assembly and a second distal end of the rods is coupled to the lower assembly. The rods extend along an outer surface of the float assembly and the float assembly is movable along the rods between a first position proximate to the upper assembly and a second position proximate to the lower assembly. The float assembly prevents fluid flow out of the outlets when disposed in the first position.

Scalable greenhouse gas capture systems and methods to allow a user to off-load exhaust captured in an on-board vehicle exhaust capture device and to allow for a delivery vehicle or other transportation mechanism to obtain and transport the exhaust. The systems and methods may involve one or more exhaust pumps, each with a multi-function nozzle assembly including an exhaust nozzle corresponding to a vehicle exhaust port and a fuel nozzle for supplying fuel to a vehicle fuel tank. Upon engagement with the vehicle exhaust port, the exhaust nozzle may create an air-tight seal between the exhaust nozzle and the vehicle exhaust port. An exhaust conduit may be configured to transport captured exhaust therethrough from the exhaust nozzle to an exhaust holding tank connected to and in fluid communication with the exhaust conduit.

A gravity-fed fuel delivery system is provided. A central storage tank holds fuel to re-supply a number of pump trucks or other mechanized equipment, such as on a hydraulic fracturing location, and can be selectively raised or lowered. Hoses or other conduits extend from the central storage tank to individual fuel tanks of the equipment to be refueled. Adapters allow connection of the distal end of each hose or conduit to an inlet opening of a fuel tank. A float valve assembly senses when fuel inside an individual fuel tank is below a predetermined level, thereby mechanically opening a valve assembly to permit fluid to flow from the central storage tank, through a conduit, through the float valve assembly and into the fuel tank.

In general, intelligent fuel dispensers are provided. In at least some implementations, an intelligent fuel dispenser can determine customer identities and/or other characteristics and provide customized fueling sessions based on the determined customer identities and/or other characteristics. In at least some implementations, the fuel dispenser includes a touchless interface allowing customers to complete fueling sessions with minimal physical contact with the fuel dispenser.

A mobile fuel monitoring system (MMU) is disclosed. The fuel monitoring system may be skid mounted and is configured to monitor fuel transfers between a fuel source and a vessel, such as a ship. The disclosed MMU is a stand-alone, self-contained unit that can be easily moved from place to place. The MMU is configured to monitor and remotely report custody transfers of fuel performed at any location. Parameters of the fuel transfer operation, such as the amount of fuel transferred, the flow rate, the fuel density, and fuel temperature can be monitored and alarms may be issued if any of the parameters are out of specification. The parameter values may be transmitted to a remote location, for example, via a satellite link.

A fuel dispensing system comprising a fuel tank adapted to contain a quantity of fuel. A fuel dispenser is in fluid communication with the fuel tank via piping. A pump operative to transfer fuel from the fuel tank to the fuel dispenser is also provided. The fuel dispensing system further comprises a corrosion detection assembly operative to identify presence of a corrosive substance in the fuel. The corrosion detection assembly includes at least one corrosion sensor positioned to be in contact with fuel vapor in the fuel dispensing system, the corrosion sensor producing a detector signal indicating presence of the corrosive substance. The corrosion sensor according to this aspect has a printed circuit multilayer structure in which at least one sensing element is positioned on an exposed surface of the multilayer structure and at least one reference element is positioned on an inner surface of the multilayer structure to be unexposed to the fuel vapor. Electronics in electrical communication with the corrosion sensor are operative to interpret the detector signal and produce an output if the corrosive substance is present.

A refueling system has a fuel tank, a sealing member, a camera, and a controller. The fuel tank includes a main chamber. The sealing member is disposed between the main chamber and the atmosphere. The sealing member is configured to selectively move between a first position in which the fluid communication between the fuel tank and atmosphere is allowed and a second position in which fluid communication with atmosphere is inhibited. The camera is configured to retrieve an image of a fuel source within a predetermined proximity of the fuel tank. The controller is configured to actuate the sealing member in response to an evaluation of the image determining that fuel from the fuel source is consumable with the fuel tank.
