A system comprising a plurality of ports is capable of automated, remote detection of conditions indicating that refill is required in one of a plurality of remote tanks and causing refill of the tank via at least one of the plurality of ports. Further, the system includes automated monitoring and supply of a fuel tank.

A system includes a plurality of mobile fuel distribution stations. Each mobile fuel distribution station includes a mobile trailer, a pump, a manifold, a plurality of hoses, a plurality of fuel caps connected or connectable with the hoses and attachable on fuel tanks of pieces of equipment, a plurality of valves, and a plurality of fuel level sensors operable to generate signals indicative of fuel levels in the fuel tanks. The mobile fuel distribution station is configured to operate the pump responsive to a low fuel threshold to provide fuel to the manifold, from the manifold to the valves, and from the valves through the hoses. A server is operable to communicate with the mobile fuel distribution stations. An electronic device is operable to communicate with the server and display the fuel levels in real-time.

A fuel delivery system and method for reducing the likelihood that a fuel tank of equipment at a well site during fracturing of a well will run out of fuel. A fuel source has plural fuel outlets, a hose on each fuel outlet of the plural fuel outlets, each hose being connected to a fuel cap on a respective one of the fuel tanks for delivery of fuel to the fuel tank. At least a manually controlled valve at each fuel outlet controls fluid flow through the hose at the respective fuel outlet.

The filling module includes: a first receptacle to be coupled to a first filling nozzle on a gas station side; a second receptacle to be coupled to a second filling nozzle on the gas station side; a first transmitter to transmit infrared rays to a first receiver disposed on an end portion of the first filling nozzle, the first transmitter being provided near the first receptacle; a second transmitter to transmit infrared rays to a second receiver disposed on an end portion of the second filling nozzle, the second transmitter being provided near the second receptacle; and first and second screen portions that project toward the gas station, the first and second screen portions being provided between the first transmitter and the second transmitter.

A multiply-redundant system that protects fueling of rockets, aircraft and other vehicles using Liquefied Natural Gas (LNG) along with an oxidizer such as Liquefied Oxygen. One or more sensors in combination with one or more optional microswitches combine to detect any leaks, fire or explosion hazards quickly locking out further fueling. For different levels of safety, different combinations of sensors can be used.

A system includes one or more mobile fuel distribution stations that have a mobile trailer, a pump, a manifold, a plurality of hoses, detachably connectable fuel caps connected or connectable with the hoses, valves, and fuel level sensors. The mobile fuel distribution station is configured to operate the pump responsive to a low fuel threshold to provide fuel to the manifold, from the manifold to the valves, and from the valves through the hoses. One or more servers are operable to communicate with the mobile fuel distribution station. The server is configured to receive fuel operating parameter data from the mobile fuel distribution station, determine whether the fuel operating parameter data is within a preset limit, and send a control action in response to the operating parameter data being outside the preset limit.

A fuel head assembly for a fuel tank has a fuel head body, an inlet connector, an inlet tube, an overflow tube, and a fuel level sensor. An upper end of the fuel body has an inlet port, a sensor port, an overflow port, and a vent port. The lower end of the fuel head body is connectable to the fuel tank. The inlet connector is connected to an upstream end of the inlet port. The inlet tube is connected to a downstream end of the inlet port. The inlet tube extends into the fuel tank. The overflow tube is connected to the overflow port. The fuel level sensor is positioned in the fuel sensor port and has a portion extending into the fuel tank
