The flow meter can be placed between an air motor and a valve. The flow meters can be placed downstream and upstream of the valve, respectively. The flow meters can be placed downstream and upstream of a joint, respectively. The flow meters can be placed downstream and upstream of a pump, respectively.

Provided is an apparatus for ejecting viscous liquid aerosol, and more particularly, an apparatus for ejecting viscous liquid aerosol capable of dispensing a viscous liquid to a work with a fine line width by ejecting the viscous liquid in the form of aerosols. The apparatus for ejecting viscous liquid aerosol may be configured compactly by miniaturizing a device capable of aerosolizing and ejecting viscous liquid in the form of aerosols. In addition, since the apparatus for ejecting viscous liquid aerosol has a structure that is easy to miniaturize, it is easy to uniformly maintain the characteristics of aerosol.

A coating apparatus can include a spray applicator configured to discharge a coating material toward a surface of a workpiece, wherein the spray applicator includes an air shaping orifice, and wherein the spray applicator is configured to generate an electric field between the spray applicator and the workpiece, and a positioning system configured to adjust a position of the spray applicator relative to the surface of the workpiece. It can further include a control system configured to regulate operation of the spray applicator and/or the positioning system to: maintain the spray applicator within a coating distance, maintain a flow rate of shaping air through the air shaping orifice, and maintain an electrical potential of the electric field.

A work machine can include a frame; a spray system couple to the frame and including a spray bar having a plurality of nozzles; a pressure sensor to detect a pressure of a liquid within the spray bar; and a controller to determine whether the detected pressure of the liquid within the spray bar has exceeded a pre-determined pressure threshold.

A printing apparatus includes a carrying platform on which a substrate is placed, a cartridge configured to store and supply ink, and a print head configured to atomize the ink into ink droplets and deposit the ink droplets on a printing region of the substrate.

A powder conveying device for coating powder includes a powder conveyor having a powder outlet duct and a powder outlet valve for opening or for closing the powder outlet duct. Additionally, a setpoint value generator for specify a setpoint opening period of the powder outlet valve, and a sensor for determining the actual opening period of the powder outlet valve are provided. The powder conveying device furthermore includes an evaluation unit for determining the deviation between the setpoint opening period and the actual opening period.

The present invention relates to a method and apparatus for delivering droplets of fluids onto an open tray (15) containing poultry. According to the invention, the apparatus comprises a stationary working surface, a single arm (16) supporting a plurality of fluid dispensing nozzles, a drive unit for driving the translation of said arm (16), said plurality of dispensing nozzles being connected to at least one fluid supply circuit comprising a fluid reservoir and a pumping unit, a control unit configured to control the drive unit of the arm and to define at least one duration T of travel of the arm (16) above said working surface. The travel time T includes a period of gradual acceleration of said arm (16) outside an area of said working surface occupied by said tray and bringing said arm to a first end of said tray (15) along the first direction at a travel velocity V, a period of constant velocity V when the arm (16) moves above said tray (15), and a period of gradual deceleration of said arm (16) when the latter has passed a second end of the tray (15) along the first direction. The control unit is also configured to control each pumping unit and activate each pumping unit only when said arm is above said tray.
