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.

For a reliable determination of through flow, it is currently necessary to work with external measurement devices in the case of flow machines. In particular, in contrast to displacer machines, there is no dependence of the through flow on the speed of rotation.

In order to be able to do without an external measurement device, the present invention goes back to the use of pressure sensors, which, in combination with the collection of additional data of the motor or of the conveyed medium, allow a determination of the through flow.

A method of delivering a fluid to a fluid consuming asset having a fluid tank is disclosed. A first tank is filled with the fluid and is fluidically coupled to a second tank which may be pressurized by a compressor. The second tank is fluidically coupled to a manifold which is in turn coupled to a fluid transporting mechanism. The fluid transporting mechanism is fluidically coupled to a hydraulic connector of a fill cap which is coupled to an opening of the fluid tank. The fluid is directed from the first tank to the second tank, the manifold, the fluid transporting mechanism, the hydraulic connector and into the fluid tank through an outlet of a probe of the fill cap.

An onboard apparatus, system, and method for automatically loading into or unloading from a bulk transport or other container and evaluating characteristics of a liquid during the loading or unloading, that dynamically monitors and evaluates characteristics of the flow, particularly density, which are used to determine other characteristics and values of the load, namely, presence of contaminants such as water, solids, out of specification conditions, etc. to enable accurately measuring volume, mass, and/or quality of the load, and optionally to automatically responsively perform certain operations, for example, to signal an operator, cease loading, segregate and/or return all or portions of the load, if contaminated or out of specification, and which facilitates control remotely, as well as for qualifying for government certification for custody transfer.

A fluid management system includes a fluid management controller and a fluid dispenser. The controller authorizes control of the one or more fluid management components over a wireless interface. A dispensing meter can be activated by an authentication device. The fluid meter includes a cartridge valve with a valve cartridge and a valve stem. 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 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.

A fuel delivery tracking assembly includes a fuel pumping unit that is fluidly coupled to a fuel tank for pumping fuel from the fuel tank. A monitoring unit is fluidly coupled to the fuel pumping unit. The monitoring unit records the flow of fuel through the fuel pumping unit for determining the fluid quantity of the fuel delivered from the fuel pumping unit. A data storage unit is included and the data storage unit is in wireless electrical communication with the monitoring unit. The data storage unit receives the fluid quantity of fuel delivered from the monitoring unit for the purposes of analysis and cost accounting with respect to the fuel delivered.

A device for refueling an aircraft, including a fuel flow duct, the downstream end of which is equipped with a wing coupler for connecting it to an inlet orifice of a fuel tank of the aircraft. The wing coupler includes a body, and a front valve that is movable with respect to the body. The wing coupler includes at least one detection member for detecting the position of the front valve, and an electrical or electronic transmission system for transmitting to a processing unit a signal representing the position of the front valve as detected by the at least one detection member.
