An attachment element for a static mixer and an attachment system with such an attachment element, the static mixer, and a pressure sensor. The attachment element has a flow channel with an inlet opening and an outlet opening arranged opposite the inlet opening in a longitudinal direction of the flow channel and designed as an injection nozzle. The attachment element is designed to be fastened at an inlet side having the inlet opening by a fastening unit of the attachment element on top of an injection tip of the static mixer. Furthermore, the attachment element has a receiving opening for the pressure sensor. The receiving opening extends from an exterior side of the attachment element to an opening in a subsection of a channel wall of the flow channel.

A nozzle assembly for use with an agricultural crop sprayer includes a nozzle body and a turbine element journaled to the body. The turbine element has a fluid-conveying internal passage having a rifled profile. Other nozzle assemblies have a nozzle tip journaled to a nozzle body, and the nozzle tip has a fluid-carrying passage with a surface profile configured to interact with fluid passing therethrough to apply a torque on the nozzle tip.

A spray nozzle for an agricultural sprayer includes a first actively controlled valve configured to control flow through the spray nozzle. A first pressure sensor is disposed upstream of the valve and a second pressure sensor is disposed downstream of the valve. The position of a valve member of the valve can be sensed, and a size of a restrictive orifice defined by the valve can be determined based on the sensed position of the valve member. A controller is configured to determine a flow rate through the valve based on a difference between a first pressure reading from the first pressure sensor and a second pressure reading from the second pressure sensor.

A sensor for determining the oscillating frequency in a fluidic oscillating nozzle and provides an oscillating nozzle, comprising a fluidic oscillator with inlet and outlet and a main channel and at least one control passage surrounding the main channel, and a splitter comprising at least two splitter channels which is attached to the outlet of the fluidic oscillator, wherein the sleeve of at least one of the at least two splitter channels comprises partially a flexible foil. The invention also relates to a method for monitoring a dispensed fluid jet, comprising the steps of providing an oscillating nozzle as described above; and injecting a fluid jet and in parallel determining the oscillation frequency by determining the deformation changes of the flexible foil.

A water jet device for recreational purposes, in particular a fountain, having: a jet head with at least one water infeed opening and at least one set of water outlet nozzles, the nozzles being arranged in a same plane and on a peripheral line of the jet head, the nozzles including respective outlets oriented towards the outside of the jet head, a water flow regulator supplying the nozzles to produce a water velocity defining a water jet, exiting each nozzle, having a selected substantially parabolic-shaped path, the water jets exiting the nozzles forming at least one dome portion, and at least one water supply column made of a rigid material and including an inlet connected to a water infeed and a water outlet connected to the opening of the jet head and mechanically integral thereto, the supply column having the selected parabolic shape to blend with the dome portion.

A fluid delivery system includes a status indicator and control system comprising a processor. The processor is configured to receive a first signal indicative of a first status of operations of a spray application system. The processor is further configured to provide to an operator of a spray gun, via a display system, a visualization representative of the first status of operations, and techniques to control the fluid delivery system, wherein the spray application system is configured to deliver at least one fluid to the spray gun during operations.

By measuring a position of a spray gun relative to a physical surface to coat, using data on technical characteristics of the spray gun, like a spray cone the spray gun may produce and data on a coating fluid used, characteristics of a coating layer thus physically deposited may be reconstructed. With data being recording during the spray job, this is faster and more accurate than measuring layer thickness at various locations, either pre-determined or randomly. By determining flow characteristics in a spray cone and position of the spray cone relative to the surface over time and using a model of the spray cone, deposition of the layer of coating may be determined and the final layer, cured or uncured, may be reconstructed, including thickness.

A programmable, electronically controlled sprinkler system has a hermetically sealed internal chamber which encloses all of the internal water flow, valves, mechanical and rotational components. A plurality of magnetic coupling arrangements allows external motors to control operation of the internal mechanical components without requiring any hydraulic seals.

A foam generating device includes a housing defining an agitation chamber and a conditioning chamber. A cartridge assembly arranged within the agitation chamber defines an agitation flow path of the solution to increase a quantity of a gas in the solution. A conditioning assembly arranged within the conditioning chamber defines a tortuous flow path for the solution including a plurality of cylindrical discs configured to sequentially receive the solution. Each of the discs defines a plurality of radial ribs on a first side and on a second side opposite the first side, the first and second sides separated by a floor, and a disc passage defined in the floor. The conditioning assembly is adjustable in order to selectively define the tortuous flow path with a first quantity of radial ribs and second quantity of radial ribs in order to alter the aeration of the solution along the tortuous path.

A method for monitoring a nozzle mouthpiece for placing on a nozzle for spraying materials, in particular dispersions, emulsions or suspensions.
