With the use of electromagnetic radiation sources, such as lasers emitting light, and corresponding detectors, spray patterns from spray nozzle assemblies can be sampled and compared to one or more calibration patterns to determine if nozzles of spray nozzle assemblies are worn out. A unique calibration pattern could be used to compare for each spray nozzle assembly, and/or a single calibration pattern could be used to compare for multiple spray assemblies. In one aspect, detectors can be arranged near sources to detect electromagnetic radiation reflected by spray patterns. In another aspect, detectors can be arranged opposite of sources to detect electromagnetic radiation transmitted through a spray pattern.

The shower head nozzle as disclosed herein includes a quick-connect coupling for selectively attaching the nozzle to a downwardly extending conduit or tube for directing tested water through a test unit and into a bucket or drain, wherein the test unit may include a flow meter for measuring real-time water flow rate and a temperature sensor for measuring real-time water temperature dispensed from the shower head, thereby reducing the testing time, more accurately determining flow-rate and water temperature, and decreasing the amount of waste water.

A dispenser system for a pressurized canister including an actuator including components such as an external housing, a valve having a top stem connector for attachment to an output hose, support pins, and a one way ball check valve having a stem fitting with an extended valve stem for engaging the pressurized canister, a pivoting actuator control or trigger, having a trigger return spring, to bias the trigger out of engagement with the valve, unless a stop pin is removed and the trigger is pivoted into operating engagement under compression of the trigger and trigger return spring by a user. The sensor may communicate with a mobile device to indicate when to stop dispensing contents from the canister.

A spray system and method for testing the flow rate of individual nozzles in the spray system are disclosed. The spray system can include a spray tank for holding a fluid to be sprayed, a pump in fluid communication with the spray tank, a manifold in fluid communication with the pump, a plurality of spray nozzles in fluid communication with the manifold, a main flow meter located in a first branch line in fluid communication with the pump and the manifold, a nozzle check flow meter located in a second branch line in fluid communication with the pump and the manifold, and a valve assembly for operating the spray system between a normal operation mode and a nozzle test mode, wherein in the normal operation mode, the valve assembly directs flow to the main flow meter, wherein in the nozzle test mode, the valve assembly directs flow to the nozzle check flow meter.

A method of equalizing a spray system for an agricultural sprayer includes measuring an output flow rate or fluid pressure for one or more nozzles on a boom assembly, determining an amount of tilt of the boom assembly with respect to a reference frame, and associating the amount of tilt with the output flow rate or fluid pressure for each of the one or more nozzles. The method also includes determining tilt-updated flow settings for the spray system based on the output flow rate or fluid pressure and storing the tilt-updated flow settings in a spray profile for later use during a spray operation.

A wireless metered fluid dispenser brings discrete fluid dispense events inside of a fluid management system. The wireless metered fluid dispenser allows a customer to visually confirm the fluid being dispensed and provides automatic tracking of the fluid dispense event within a wireless tracking system. A volumetric flowmeter attached to the bottom of a container or funnel tracks the amount of fluid dispensed when pouring from a container. The volumetric meter is wirelessly connected to a computer system for the transmission of data, for the purpose of centralized control and billing.

An electric solenoid valve, methods for operating and/or actuating the solenoid valve, valve system diagnostics, and applications for use are described. The valve may be designed to actuate in a manner so as to control liquid flow into and/or through a device, such as a spray nozzle. By altering the characteristics of the electrical signal transmitted to the solenoid valve, the instantaneous pressure across the valve and duration of fluid flow through the valve can be controlled with a single actuator. Controlled cyclic durations of flow may be implemented to regulate the exact timing of flow through the valve. Alternatively, cyclic durations may occur with a pulse-width modulation technique in which the duty cycle regulates average flow rate through the valve.

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 drain clearing air gun includes a housing defining a main body, a handle positioned on a first end of the main body, and a nose positioned on a second end of the main body. A tank is at least partially positioned within the housing and includes a chamber for receiving pressurized air, where the tank has a first portion and a second portion that are coupled together to form the chamber. The first portion is disposed within the nose of the housing and is formed of a first material. The second portion is disposed within the main body of the housing and is formed of a second material that is different than the first material.

A filter system that includes: a shower head; a filtration system integrated within the shower head; and a set of water flow nozzles on the shower head. The filter system also includes a sensor, where said sensor measures water flow through the shower head. The sensor includes an alerting mechanism related to water flow, where said alerting mechanism is a light.
