An automated liquid dispensing attachment monitors and controls preparation of drinks poured from bottles. The automated liquid dispensing attachment attaches to a bottle and senses multiple aspects of the pouring of the drink, and based on the sensor outputs, monitors and controls the flow of fluids from the bottle through the attachment. The automated liquid dispensing attachment communicates with other electronic devices to enable individualized control and monitoring, and data aggregation and analysis.

The present invention relates to a An electromagnetic flowmeter for measuring flow of fluid flowing in a conduit of the electromagnetic flowmeter, wherein the electromagnetic flowmeter comprises: a coil attached to an inner surface of the conduit; a movable magnetic ring having segments of magnetic materials that is magnetically coupled with the coil to generate an electromagnetic field to interact with the fluid flowing through the conduit wherein the conduit is provided with an insulating liner. A pair of electrodes mounted on the conduit for measuring potential difference generated by the interaction of the electromagnetic field in the fluid. Wherein the segments of magnetic materials are having varying magnetic properties arranged to have an orderly varying electromagnetic field in the conduit adjustable by rotating the movable magnetic ring. The movable magnetic ring is positioned between the at least one coil and the insulating liner.

Devices, methods, and systems for operating gas meters are described herein. The systems may include a gas measuring system connectable to a gas line, where the gas measuring system may include a flow rate sensor, a pressure sensor, and a controller in communication with the flow rate sensor and the pressure sensor. The flow rate sensor and the pressure sensor may be configured to sense measures of a gas passing through the gas line. The controller may repeatedly obtain pressure measurements at set pressure measurement times. Measures from the flow sensor may be monitored and when a measure from the flow sensor measure meets a flow rate criteria, the controller may trigger an extra pressure measurement without waiting for a next pressure measurement time. The controller may initiate closing of a gas valve when a measure from the pressure sensor exceeds a threshold value.

A flow rate control apparatus can obtain a flow rate of a fluid passing through a downstream-side valve in a form in which noise is significantly reduced with little time delay, and has improved responsiveness. The flow rate control apparatus includes: a downstream-side valve flow rate meter that measures a downstream-side valve flow rate that is a flow rate of a fluid passing through a downstream-side valve; and an observer including a downstream-side valve flow rate estimation model that estimates the downstream-side valve flow rate on the basis of an input parameter that changes an opening degree of the downstream-side valve. The observer is configured so as to be fed back a deviation between the measured value of the downstream-side valve flow rate and the estimated value of the downstream-side valve flow rate.

A method for calibrating a product valve disposed along a flow path in a duct, with a calibration valve in a duct remote from the product valve and having a geometric shape and operational parameters corresponding to those of the product valve. A calibration controller establishes calibration conditions and, in responsive thereto, generates a calibration flow rate (CFM) function by measuring for the calibration valve, a sparse set of flow rates and determining a surface-fit mathematical representation of fluid flow through the calibration valve over applied calibrated flow rates and the measured pressure drops. The CFM Function is transferred to a product blade controller, which in turn, processes the representation of the mathematical surface, and controls fluid flow through product valve based on values extracted from the received CFM Function as well as at least one parameter control signal indicative of a desired set point.

A fluid delivery system for an appliance includes a fluid line in selective communication with a fluid source. A shelf defines a fill zone positioned below an underside of the shelf. A shelf spigot is coupled with the fluid line and disposed proximate the underside of the shelf and over the fill zone. A fluid level sensor is positioned in communication with the fill zone. The fluid level sensor is also in communication with a controller that regulates a flow of fluid through the shelf spigot.

A method for calibrating a product fluid flow valve disposed along a flow path in a site duct, and including damper blades, an actuator coupled thereto, a differential pressure sensor, and a blade controller adapted to define adjustable product flow apertures, comprising the steps: with a calibration fluid flow valve in a calibration duct remote from the product fluid flow valve, and characterized by a geometric shape and operational parameters corresponding to those of the product fluid flow valve, and with a calibration controller, establishing a plurality of calibration conditions including pressure drop across the calibration blades and area of the calibration apertures, determining a calibration flow rate (CFM) function, transferring the CFM function to the product blade controller and adjusting the adjustable product flow apertures so that a parameter set point is attained. In a form, fluid flowing through the product flow apertures forms a vena contracta.

A method for determining the flow rate of combustible fluid injected into a combustion chamber (120) of a turbine (100) includes determining the cross section of the orifice of the at least one injector (112, 113, 114, 115) through which the combustible fluid is injected into the combustion chamber (120). The pressure of the combustible fluid upstream of the orifice of the injector (112, 113, 114, 115) is determined. The pressure downstream of the orifice of the injector (112, 113, 114, 115) is determined. The flow rate of combustible fluid flowing through the orifice of the at least one injector (112, 113, 114, 115) is determined.
