A distribution station includes a mobile trailer, a pump on the mobile trailer, a manifold on the mobile trailer and connected with the pump, a plurality of hoses connected with the manifold, a plurality of valves on the mobile trailer, each of the valves situated between the manifold and a respective different one of the hoses, a plurality of guided wave radar level sensors, each of the guided wave radar level sensors being associated with a respective different one of the hoses, and a controller configured to communicate with the guided wave radar level sensors and operate the valves responsive to signals from the guided wave radar level sensors.

A distribution station includes a mobile trailer, a pump, a manifold connected with the pump, reels, flow passages connected to the manifold and running through the reels, hoses, connected the flow passages via the reels, valves situated between the manifold and the reels and operable to control fluid flow through the flow passages, fluid level sensors connected or connectable with the hoses, and a controller configured to operate the valves responsive to fluid level thresholds to control fluid flow to the hoses.

An apparatus is provided. The apparatus may include an elongated shaft including a passage terminating at a nozzle including a dispersion plate and tapered sidewalls between the dispersion plate and the elongated shaft. The tapered side walls may define a single opening, an outer surface of the sidewalls may define a tapered exit for the opening, an inner surface of the sidewalls may define a non-tapered entrance into the opening, the nozzle is sized to be received by a transmission case inlet, and an internal diameter of the passage is less than the tapered exit.

The present invention relates broadly and separately to a flow control valve and a float control valve assembly for use in the refilling of storage vessels, particularly fuel tanks. The invention also relates generally to a vessel overfill protection system. The flow control valve comprises a valve body defining a fluid passageway disposed between a fluid inlet and a fluid outlet and a piston assembly located at least in part within the fluid passageway. The piston assembly includes a piston support to which a piston is slidably mounted for opening and closure of the fluid outlet. The piston support includes at least one fluid sampling passage arranged to provide pressurised fluid from the fluid inlet to an upstream surface of the piston which is urged for opening of the fluid outlet to permit flow of fluid through the fluid passageway. The float control valve assembly includes a float assembly body adapted to mount within a vessel to be filled with fluid via the flow control valve. The float control valve includes a pilot valve and a pilot control passage in fluid communication with the flow control valve. The pilot valve is operatively coupled to a float member for closure of the pilot control passage on flooding of the float housing to promote closure of the flow control valve.

A mechanical system for calibration during a chemical feed process includes a ball valve that includes three openings. The ball valve is in communication with a lever, which when turned to a fill position, allows the filling of a drawdown cylinder for calibration. The ball valve automatically returns to its original default position within about a minute with a spring force automatically pushing it back to its start position.

Method and system for measured dispending of a liquid to a target reservoir. An oval gear flow meter provides two pulses from different magnets. A pipe subsystem allows liquid from an above-ground reservoir measured through the oval gear flow meter to be controllably dispensed using a controllable valve. A processor module, upon receipt of a start-signal, opens the controllable valve and, until receipt of a stop-signal, computes a volume of the liquid dispensed by the system into the target reservoir by counting the pulses as a first and second counts. An adjustable volume-per-count value is computed with the count(s) to obtain the volume of liquid dispensed. The processor generates an error when a difference between the two counts is greater than a predetermined threshold set considering a target precision setting for the dispensing system.

An electromechanically operated fuel nozzle having continuously adjustable flow rate settings between a closed position and maximum flow. The fuel nozzle includes a fuel dispensing pipe for dispensing fuel; an electromechanical valve device to control a flow of fuel in the fuel dispensing pipe, comprising an inlet pipe and an outlet pipe. The electromechanical valve device comprises at least one continuously variable flow electromechanical valve to control the flow of fuel; an electronic board for operating the at least one continuously variable flow electromechanical valve; and electric accumulator means for electrically powering the at least one variable flow electromechanical valve and the electronic board such that the predetermined portions provide the particular one of the flow rate settings. The electromechanical valve preferably comprises a servomotor controlled ball valve.

To prevent fuel from leaking to outside even when the fuel flows back at the time of an automatic stop operation during refueling. A fuel supply portion structure of a fuel supply pipe, including a tubular portion having a filler port and a connection port, a first flap mechanism which is provided on the filler port side of the tubular portion, a drain hole, and a drain hole on-off valve, wherein the drain hole on-off valve is disposed on a placement surface located at the lowermost side of a vehicle on an inner wall of a first inner diameter member, the placement surface is made of an inclined surface falling from the filler port side toward the connection port with respect to a horizontal plane of the vehicle, and a wall portion rising toward the filler port is provided on the filler port side of the inclined surface.
