A filling valve for filling a container with a filling product, e.g., a beverage in a beverage filling system, includes a valve base body. The valve base body includes an outlet configured to discharge the filling product into the container; a swirl chamber configured to receive the filling product and is able to be brought into a fluidic connection with the outlet; and a main inlet, which feeds into the swirl chamber and is configured to introduce at least one main component of the filling product into the swirl chamber such that the filling product is swirled in the swirl chamber, whereby after exiting from the outlet the filling product flows downwardly in a spiral movement in the container. The swirl chamber has an annular shape, the cross-sectional contour thereof having a rounded shape, substantially without corner points, in the direction of extent and perpendicular to the direction of extent.

A multiply-redundant system that prevents a driver from starting and/or moving a vehicle if a compressed natural gas fill system is not correctly and completely disconnected from the vehicle. One or more sensors in combination with one or more optional microswitches combine to lock-out the vehicle's ignition or otherwise prevent it from starting and/or moving. For different levels of safety, different combinations of sensors can be used with the lowest level having a single proximity sensor sensing the presence or absence of a high-pressure fill hose. The highest level of safety being achieved by having separate proximity sensors on the fuel fill hose fitting, the gas cap cover and a manual safety valve along with a redundant microswitch. An optional override that may be restricted as to the number of times it can be used can allow starting with a faulty sensor in order to allow maintenance.

A method and system of dispensing a fuel from a fuel tank to a recipient fuel tank. The method includes scanning a tag by a scanner from a smart device, wherein the smart device also comprises a communications processor, recording an initial inventory level of the fuel in the fuel tank, estimating a density of the fuel, opening a valve to dispense a predetermined amount of the fuel, and recording a final inventory level after the dispensing the fuel, upon estimating that the density of the fuel is within a predetermined range, and shutting the valve and communicating to relevant personnel about the difference in fuel density, upon estimating that the density is outside of the predetermined range.

A fluid filling system for filling a tank from a source of fluid. The system is particularly beneficial for filling a DEF tank. The system has a pump connected to a fluid source, such as DEF. A fill hose has a proximal end and a distal end. The proximal end is connected to the pump. The distal end includes at least one first sensor mounted adjacent the distal end. The distal end is adapted for insertion into the tank. A CPU is operatively connected to the first sensor and the pump. The first sensor communicates with the CPU to energize the pump when the sensor fails to sense fluid when the fill hose is inserted into the tank. The CPU deenergizes the pump when the first sensor senses fluid when inserted into the tank. As a result, the fluid filling system continually fills the container through the fill hose.

A method and apparatus are provided for controlling a fuel delivery system to limit acidic corrosion. An exemplary control system includes a controller, at least one monitor, an output, and a remediation system. The monitor of the control system may collect and analyze data indicative of a corrosive environment in the fuel delivery system. The output of the control system may automatically warn an operator of the fueling station of the corrosive environment so that the operator can take preventative or corrective action. The remediation system of the control system may take at least one corrective action to remediate the corrosive environment in the fuel delivery system. One or more sensors may be employed to signal proper operation of the remediation system.

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.

Fluid storage and dispensing systems and processes involving various structures methods for fluid storage and dispensing, including, pre-connect verification couplings that are usefully employed with fluid storage and dispensing packages to ensure proper coupling and avoid fluid contamination issues, empty detect systems (e.g., monitoring pressure of dispensed liquid medium to detect pressure droop conditions) useable with fluid storage and dispensing packages incorporating liners that are pressure-compressed in the fluid dispensing operation, ergonomically enhanced structures for facilitating removal of a dispense connector from a capped vessel, cap integrity assurance systems for preventing misuse of vessel caps, and keycoding systems for ensuring coupling of proper dispense assemblies and vessels. Fluid storage and dispensing systems achieve zero or near-zero headspace character, and prevent or ameliorate solubilization effects in liquid dispensing from liners in overpack vessels.

A fleet refueling silo tank system gravity feeds fuel through hoses to fleet units without requiring pressurizing pumps. A specialized valve at the fleet unit fuel tank prevents vapor escape and admits fuel at low, gravity-feed pressures. The valve includes a valve body with an upper end and a lower end, the upper end adapted to engage a cap which affixes the valve body to the fuel tank fill mouth. Below the cap, a fuel cut-off plunger and seat selectively interrupt fuel flow through the mouth by responding to a buoyant float extending coaxially beneath the valve body and into the fuel tank. Linkage coupled to the plunger extends through the valve body to the float, and roller bearings within the valve body engage a shaft extending from the float coaxially into the lower end of the valve body.
