A liquid volume transfer system includes: a liquid infusion device, including a first communication module, a first controller and a first flow rate detecting module; a liquid container, including a second communication module; and an unmanned aerial vehicle, including a third communication module, a third controller and a second flow rate detecting module. The first controller obtains a remaining liquid volume value from the second communication module through the first communication module, and determines a target infused liquid volume value based on the remaining liquid volume value and a total infused liquid volume value; after completion of infusion, the total infused liquid volume value is sent to the second communication module through the first communication module; the third controller obtains the total infused liquid volume value through the third communication module, and sends the remaining liquid volume value to the second communication module through the third communication module after spraying.

Embodiments of the invention relate to a gas fire pit delivery and pay-station system for providing a gas service on a pay-per-use basis. The system provides a multi pay-station or a single pay-station configuration connected to a main gas supply of pressurized gas whereby a control signal is provided by the pay-station to a plurality of electronically controlled gas valves for disabling or enabling the pressurized gas to flow to one or more fire pit stations.

A system for delivering a fluid to a fluid consuming asset having a fluid tank is disclosed. An inlet of a manifold is fluidically coupled to a storage tank that contains the fluid to be delivered. A first distal end of a fluid transporting mechanism is fluidically coupled to an outlet of the manifold. A second distal end of the fluid transporting mechanism is fluidically coupled to the fluid tank. A primary valve is fluidically coupled to the fluid transporting mechanism and restricts fluid flow to the fluid tank when fluid level in the fluid tank reaches a first fluid level threshold. A secondary valve is fluidically coupled to the fluid transporting mechanism and restricts fluid flow to the fluid tank when fluid level in the fluid tank reaches a second fluid level threshold. The first fluid level threshold is lower than the second fluid level threshold.

The apparatus for monitoring the delivery of fuel oil through a fuel oil delivery pipe including a flow meter and property sensor associated with the oil delivery pipe for measuring the flow rate, temperature, viscosity, density and dielectric constant of the fuel oil as it moves through the delivery pipe. The digital output signals from the flow meter and property sensor are used to generate data signals which are a function of the measured parameters. A memory records the data signals. The actual total quantity of fuel oil delivered through the pipe is calculated based upon the data signals. A clock circuit generates a timing signal reflecting the date and time the measurements were taken. A transmission signal formed of the calculated actual total quantity of fuel oil delivered and time signal may be sent to a remote location by a WiFi transmitter or through the internet using a modem.

A refrigerator includes a dispenser having a dispenser well, a control for regulating a product dispensing operation, and an optical sensing system includes a camera within the dispenser well in communication with a controller for controlling the filling of a container within the dispenser well based on image data. The image data can used to detect at least one of a presence of a container in the dispenser well, a height of liquid within the container, a height of ice within the container and a shape of the container within the dispenser well, as well as to adjust a dispensing rate of product.

A fluid dispensing control unit is provided that includes at least one electronic circuitry processor configured to function as a web server, at least one generic purpose input/output block for connecting to a fluid dispensing system device being a fluid valve, a meter, a pump or a tank for controlling or metering the dispensed fluid or for controlling the fluid pump or tank. The fluid dispensing control unit further includes at least one web input/output block that is provided for connecting the web server to a web enabling a remote control of the fluid dispensing control unit and the connected fluid dispensing system device via the web. The at least one generic purpose input/output block and the one web input/output block are connected with the at least one electronic circuitry processor.

There is disclosed a refueling system and method for simultaneously refueling the fuel tanks of multiple pieces of machinery in the field. In an embodiment, the system comprises a mobile tanker with at least one fuel supply tank configured to connect and supply a plurality of refueling hoses. Each refueling hose has an upstream end connected to a supply line from the at least one fuel supply tank. At a downstream end, each refueling hose terminates at a mechanical open-close valve which is adapted to be inserted within each receiving fuel tank being refueled. The mechanical open-close valve is suitably shaped and sized to provide a clearance fit within the neck diameter of each receiving fuel tank being refueled, and has a buoyant body for mechanically actuating the mechanical open-close valve.

The present invention relates to automated batch making assemblies where various component materials, at least, some in liquid form, are combined. Specifically, the invention provides a dispensing assembly that adds efficiency by increasing dramatically the speed with which a liquid is dispensed from a container and by providing means and methods to automate the addition of and account for the amount of each component.
