A handheld fluid meter includes a cartridge valve controlling the flow of fluid through the handheld meter. The cartridge valve includes a valve cartridge and a valve stem disposed within the valve cartridge. The cartridge valve guides the valve stem and provides the only sealing surface for the dynamic seals and control seal disposed on the valve stem. The handheld meter dispenses through a nozzle, which includes an overmolded stem tip that generates a laminar fluid flow as the fluid exits the nozzle. The overmolded stem tip is a compliant material. The handheld fluid meter includes circuitry configured to invert the orientation of a visual output provided by a display of the handheld fluid meter to facilitate installation of the handheld fluid meter for use in an oil bar application.

An automatic shut-off fluid nozzle having a primary fluid path, a vacuum-actuated fluid shut-off assembly in the fluid path, said shut-off shutting off flow through the fluid path when the pressure chamber is subjected to a predetermined vacuum. The nozzle having a venturi port in said fluid path and connected to a vacuum channel, and a vacuum vent extending away from the vacuum channel, said vacuum vent communicating with a low vacuum environment. The nozzle further having a segregated fluid channel in the primary fluid path, the venturi port communicating with said segregated fluid channel, such that the flow of fluid past the venturi port creates a venturi vacuum in the vacuum channel. The vacuum exhausts the vacuum through the vent port when the vent port is in an open condition, and creates a vacuum in the vacuum-actuated fluid shut-off assembly when said vent port is in a closed condition.

A filling apparatus for filling gasoline and diesel vehicles at fuel oil stations and installed onto a fuel oil dispenser having a cap located on dispenser pipe entering into the vehicle tank. A diaphragm is located in the cap and operates the fuel oil way and provides flow and stop of fuel oil. A pipe sheath is installed onto the dispenser pipe and connected to the cap. A holding spring secures the pipe sheath to body of the fuel oil dispenser. A trust pipe provides a set of trust mechanism resting on the tank inlet when it is attempted to insert pipe sheath into the diesel tank. A pushing spring is connected to the thrust pipe and pushed after the tank inlet is hit by the thrust pipe. A motion spindle transmits motion from the pushing spring to the diaphragm which is moved downward and provides closing.

In a method and system for delivering fluid to a fluid consuming asset having a fluid tank, an inlet of a manifold is fluidically coupled to a tank and an outlet of the manifold is coupled to a spigot. A pressure relief valve is disposed between the tank and the manifold to facilitate fluid flow back to the tank through a recirculation inlet when the back-pressure in the system reaches a threshold value. A first distal end of a fluid transporting mechanism is coupled to the spigot and a second distal end thereof is coupled to a hydraulic connector of a fill cap having a connection plate coupled to the fluid tank of the fluid consuming asset. The fill cap further comprises a probe and fluid flows from the first tank to the second tank, through the manifold and the hydraulic connector, through the probe and into the fluid tank of the fluid consuming asset.
