A method for controlling a magnetic valve and particularly a method for dispensing and/or aspirating a volume of liquid as well as a corresponding dispenser/pipetting apparatus is disclosed. The method for controlling a magnetic valve has measuring a capacitance at the magnetic valve and determining a position of a plunger based on the measured capacitance. The method for dispensing or aspirating a volume of liquid has controlling a flow of a system fluid by a magnetic valve located between a pressure source and a dispenser/pipetting tip, dispensing or aspirating a volume of liquid through an exterior opening of the tip dependent on the flow of the system fluid, wherein controlling the flow and determining a flow time in dependence of the volume of liquid to be dispensed or aspirated, and controlling the magnetic valve is held open for the duration of the flow time.

The present invention relates to a flowmeter for monitoring physical parameters of fluid passing through the flowmeter. The flowmeter being installed in a plant and communicatively connected through a gateway device to a server having a virtual model. The flowmeter comprising: a processing unit for computing a first processed data of a physical parameter associated with the fluid measured by the flowmeter. The flowmeter receives a second processed data from the server having the virtual model, wherein the virtual model provides the second processed data by computing the second processed data based on the first processed data and data from at least one sensor provisioned in the plant. The present invention also provides for a system for monitoring physical parameters of fluid passing through a pipe in a plant with the flowmeter.

A horizontal fluent material dispenser for the even dispensing of a metered quantity of powder. A hopper holds the powder. The hopper has a mixing portion with rotating beaters. A horizontal conduit is coupled to the hopper and receives powder from the hopper. A screw conveyor—or auger—within the conduit transfers the material through the horizontal conduit. A knife assembly, disposed at the distal longitudinal end of the screw conveyor, breaks off a continuous and even flow of powdered material out the discharge opening. A modular screw conveyor assembly is disclosed for changing the material dispensing rate range without changing the conduit diameter. A dual drive mechanism is also disclosed for independent adjustment of the rotating beater speed and the screw conveyor.

A fluid dispensing apparatus includes an actuator body with an actuator and a valve stem coupled for movement with the actuator, and a fluid body having a fluid chamber capable of fluid communication with an outlet. The valve stem is adapted to extend from the actuator body into the fluid chamber for dispensing fluid from the fluid chamber through the outlet. A quick connect member is provided to selectively fully engage and disengage a first coupling element on the actuator body with a second coupling element on the fluid body, to connect and disconnect the actuator body and the fluid body with respect to each other. The quick connect member advantageously connects or disconnects these bodies without requiring disassembly or dismounting of the bodies from other elements associated with the fluid dispensing apparatus, with a simple manual movement such as a sliding linear continuous movement.

A conveyor mechanism conveys a powder along a path. A first camera device arranged above the conveyor mechanism detects movement of a recognizable feature on an upper surface of the powder over a period of time. A velocity of the powder can be determined based on the movement of the recognizable feature over the period of time. A device can be used to generate the recognizable feature. A first light-emitting device can illuminate the upper surface to aid detection of the recognizable feature. A second light-emitting device can project a contour line on the upper surface, and a second camera device can be used to detect a position of the contour line. A cross sectional area of the powder can be correlated based on the position of the contour line.

A method and a system for controlling automatic quantitative fluid supply are disclosed, and the method and the system automatically control the quantitative fluid supply by timing a period of time t required for introducing gas (20) into a sealing tank (4) in such a way that the pressure in the sealing tank (4) reaches a default value and calculating a period of time T, required for continuously introducing the gas (20) into the sealing tank (4) to extrude a fixed volume (V) of the fluid, from the time t, in the process of automatic quantitative fluid supply, so as to automatically control the switching-on and -off of a gas passage (1), overcome the impact of the reduction of the liquid level on the quantitative supply accuracy and guarantee the accuracy requirement of repeated quantitative supply.

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.

A sensor arrangement is described for determining at least one parameter of a fluid medium flowing through a measuring channel, particularly of an intake air mass flow of an internal combustion engine. The sensor arrangement includes a sensor housing, in particular a plug-in sensor which is introduced or may be introduced into a flow tube and in which the measuring channel is formed, and at least one sensor chip which is situated in the measuring channel for determining the parameter of the fluid medium. The sensor chip is attached to a sensor carrier protruding into the measuring channel. The sensor carrier is designed in such a way that it has a chord. The chord has a length of 4.5 mm to 6.5 mm. In a preferred refinement, the sensor carrier is shaped like a double ellipse or a diving board.
