An improved method of delivering fluid to a fluid consuming asset having a fluid tank. A tank filled with fluid is coupled to a manifold through a fluid delivery coupling having a first pressure relief valve set at a first predetermined pressure threshold disposed between the tank and the manifold. The fluid is directed back to the tank through a first re-circulation inlet when the first pressure relief valve opens. A second pressure relief valve is disposed between the manifold and the tank and directs fluid back to the tank when back-pressure in the manifold exceeds a second predetermined pressure threshold. The manifold is coupled to a fluid transporting mechanism which is fluidically coupled to the fluid tank. fluid flows out of the manifold into the fluid transporting mechanism, through a fill cap and into the fuel tank.

The liquid material ejector has a liquid material supply port through which the liquid material is supplied, a nozzle for ejecting the liquid material, a valve block having a metering bore to be filled with the ejected liquid material and a liquid material supply channel communicating with the liquid material supply port, a selector valve having a first channel for allowing communication between the metering bore and the liquid material supply channel and a second channel for allowing communication between the metering bore and the nozzle, a plunger advancing and retracting in the metering bore, a plunger driving section for driving the plunger, a valve driving section for driving the selector valve, and a transmission section for transmitting driving power from the valve driving section to the selector valve. The plunger driving section, the valve driving section, and the valve block are arranged successively in the longitudinal direction.

The invention comprises a main and a subsequent stage. At the main stage, the medium is pumped into a first instrument line. This first instrument line is mounted in a main pipeline system and is equipped with an inlet mass meter with a first flow rate range. After reaching of a set value from the instruments, an automated control system (ACS) stops the first line pump, ensures operation of its driving isolation valves, thus, completing the main stage measurement cycle, and switches the system into the subsequent stage mode. At the subsequent stage, the medium flow is collected from the tank and cavities of the measuring system. It flows by gravity into the bottom of the system inner volume (9) and is then supplied by a to a second instrument line equipped by a mass meter with a second and lower flow rate range.

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.
