A mobile fluid transfer system. The system includes a fluid evacuation system, a fluid refill system, a sensing system and a control system. The fluid evacuation system comprises a first fluid storage container. The fluid refill system comprises a second fluid storage container. The sensing system is coupled to the fluid evacuation system and the fluid refill system. The control system is coupled to the sensing system, the fluid evacuation system and the fluid refill system. The control system is configured to determine an amount of a first fluid in the first fluid storage container based on a first signal from the sensing system, and determine an amount of a second fluid in the second fluid storage container based on a second signal from the sensing system.

A fully-integrated, flow-control module for top-fill fuel tanks is designed to operate with a fuel line attached that supplies fuel under constant pressure. A main flow control valve within the flow-control module closes automatically when the fuel tank is full, and automatically opens when the fuel level drops a certain amount below the full level. A spring-biased valve plunger of the main flow control valve has a bleed aperture that diverts a small amount of incoming fuel to a bleed path that is controlled by a fuel level float that operates on a lever arm that either opens or closes the bleed path. When closed, fuel pressure beneath the valve plunger increases sufficiently that the plunger biasing spring is able to exert a force sufficient to close the valve plunger. Bleed path control hysteresis prevents rapid cycling of the main flow control valve.

The present invention is directed broadly to a tank overfill protection system (10) generally comprising a flow control valve (12) operatively coupled to a tank level sensor via a pilot line (16). The flow control valve (12) generally comprises: 1. a valve body (26) defining a fluid passageway (28) between a fluid inlet (30) and a fluid outlet (32); 2. a piston (34) slidably mounted within the fluid passageway (28) and arranged for displacement for opening and closure of the fluid outlet (32); 3. a bleed fluid cavity (36) located within the valve body (26) and arranged to cooperate with the piston (34); 4. a bleed fluid conduit (38) operatively coupled to the bleed fluid cavity (36); 5. a venturi arrangement (40) operatively coupled to the bleed fluid conduit (38) to promote evacuation of bleed fluid from the bleed fluid cavity (36) thereby opening the fluid outlet (32) by displacement of the piston (34).

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 and method for delivering fuel to a plurality of vehicles comprising a distribution manifold having a plurality of outlets, said distribution manifold in fluidic communication with a fuel source, each of said plurality of outlets having an associated control valve for controlling fluid flow therethrough and a plurality of tank valve assemblies in fluidic communication with one of said plurality of fuel lines each located at an inlet to a tank of one of said plurality of vehicles, each of said tank valve assembly being operable to shut off flow of fuel therethrough when said tank is filled to a predetermined level. The system further comprises a plurality of fuel lines, each of said plurality of fuel lines extending between an outlet of said distribution manifold and a tank valve assembly and a controller operably coupled to said plurality of control valves wherein said adapted to sequentially open at least one of said plurality of control valves at a time.

A personal vaporizer has a hollow tube that extends from an atomizer through a tank for holding vaporization media. The hollow tube has a filling hole formed through a side wall thereof. To fill the tank, vaporization media can be injected into a mouthpiece and flows into the hollow tube. A divider wall in the hollow tube deflects vaporization media through the filling hole and into the tank. After the tank is filled with vaporization media, vaporizer is moved to an assembled configuration in which the filling hole is blocked.

Method for autonomously fueling machinery operating at fracking sites. A fuel tank with a plurality of fuel lines individually coupled to a fuel tank are used. Pumps are connected to some of the fuel lines. Pump outputs are coupled to hoses extending to machinery tanks to be refueled. A cap is detachably connected to the hoses and machinery tanks to be fueled. The fuel tank includes an intake filter capable of blocking approximately 10 micron contaminants with about 250 gallon per minute flow rate. The methodology of the present invention includes measuring the duration of machinery tank fuelings and the interval between fuelings. A first alarm is generated if the duration of fuelings is longer than a first interval. A second alarm is generated if the interval between fuelings is longer than a second interval.

Improvements in a portable vehicle fueling kiosk is disclosed. The kiosk is constructed on a pallet or a skid that allows the kiosk to be placed, located or moved to a location where the fuel dispensing is desired. A fuel tanker that would normally dispense fuel to a storage tank of a gas station is connected to one side of the kiosk. The kiosk accepts payment by nearly any form of money, credit card or token to measure, dispense and bill or invoice the user. The kiosk can have a Wi-Fi or cellular communication to communicate with a user at a distance and can monitor, use, status and remaining fuel in the tanker. If a fuel tanker has been depleted additional tankers can be connected to the kiosk, and when the kiosk is no longer needed it can be transported to another location.

A system for delivering fuel to an equipment fuel tank. The system includes a remote fuel storage tank and a valve assembly coupleable to the equipment fuel tank. The system includes a fuel supply line extending between the remote fuel storage tank and the valve assembly and a pneumatic valve disposed in the fuel supply line. The pneumatic valve can prevent flow of fuel into the fuel supply line or can enable flow of fuel into the fuel supply line. The valve assembly includes pressure tubes to detect changes in fuel level inside the equipment fuel tank. A switch actuates the pneumatic valve to prevent the flow of fluid in response to an overfilled position; and actuates the pneumatic valve to enable the flow of fluid in response to an underfilled position.

The present invention provides a smart and automated system that is used for refueling of frac truck tanks during fracturing operations. The system is used to refuel the frac truck tanks which are constantly working in the high pressure and high-temperature zone for the fracturing of the wellbore to extract oil and gas. For safety, the system is equipped with explosion/fire free wiring system. The system incorporates inventive fuel valve to avoid the fuel clogging that increases the frac truck performance. The system employs artificial intelligence (AI) and cloud-based software for ease of operation and to maximize economic performance. The system is equipped with artificial intelligence and Programmable Logic Controller (PLC) software and incorporates charge pump and loop systems which maintain a predetermined pressure (in Pounds per Square Inch (PSI) unit) in each loop so as to maximize the performance and control function in the refueling system.
