A method of deploying a water intake device in a fuel storage tank involves providing a water intake device having an elongate flow structure including at least one flexible flow tube and an elongate substrate adjacent to the flow tube, wherein the substrate provides a semi-rigid characteristic that allows the elongate flow structure to be guided. Another step of the method involves providing a guide tube having a straight portion and an arcuate portion at a distal end of the guide tube. Another step of the method involves installing the guide tube generally vertically into a fuel storage tank with the arcuate portion directed toward a desired guidance direction. Another step of the method involves moving the elongate flow structure of the water intake device through the guide tube into a deployed position.

A water intake device for use in a fuel storage tank comprises an elongate flow structure including a plurality of flexible flow tubes having respective first ends of different lengths and a second end at a common location. A header manifold is in fluid communication with the second ends of the flow tubes, the header manifold having a single connection port. In addition, the header manifold is configured to allow flow between the flow tubes and the connection port.

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. A payment system includes a PIN pad that transmits secure tokens which are preferably cryptographically unique and independent such as not to be a function or derivative of network keys or user PIN. The tokens are then received and acted upon by a second subsystem to render PIN entry display data.

Computer-implemented method to control a dispensing machine configured to deliver fluid products inside a receptacle (118) and comprising a plurality of containing units (111), each containing a respective fluid product, one or more storage zones (128) of the containing units (111) and a dispensing zone (115) wherein it is provided to temporarily and selectively locate at least one sub-assembly of containing units (111) containing the fluid products to be delivered in a dispensing cycle, making use of a computing device (161) comprising at least one processor (164), data storage means (162) with a formulation database, an input device (163), and a display device (159), wherein the control method comprises determining the disposition of the plurality of containing units (111) in the dispensing zone (115) and in the storage zone(s) (128), receiving, via the input device, a target formulation, selected by the user, and identifying, via the processor, from the formulation database an associated plurality of fluid products contained in respective containing units (111) of the sub-assembly, each to be delivered according to a predetermined quantity to obtain said target formulation. The computer-implemented control method also comprises displaying a graphic representation of the layout of the dispensing machine with the dispensing zone (15) and the storage zone(s) (28), which respectively reflects the disposition of the sub-assembly of containing units (111) disposed in the dispensing zone (115) and in the storage zone(s) (128), and graphically highlighting, in the graphic representation, at least the sub-assembly of containing units (11) from which the selected target formulation is to be produced by means of signaling means so as to facilitate their identification by the user and thus provide guidance to the user for displacing of one or more than one containing unit(s) (111) from the storage zone(s) (128) to the dispensing zone (115), or vice versa, if required for the production of the target formulation.

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.

A fuel storage and supply arrangement serves as a source of fuel to be dispensed via at least one fuel dispenser in a fuel dispensing environment. The arrangement comprises a storage tank for containing a quantity of the fuel. A pump assembly draws the fuel from the storage tank providing the fuel under pressure to a fuel supply line. A fuel conditioning assembly includes a housing having a storage volume, a housing inlet receiving the fuel under pressure created by the pump assembly, a housing outlet through which fuel exits the housing, and a housing port through which fuel can be drawn into the housing. A vacuum source in fluid communication with the housing outlet is operative to selectively apply a vacuum to the outlet of the housing so that liquid can be drawn into the housing via the port. A water intake device is in fluid communication with the housing port. The water intake device has at least one inlet situated adjacent to a bottom of the fuel storage tank.
