A medicament preparation system includes a disposable cartridge with a flow path. Various sensors may be placed on the cartridge to measure qualities of the fluid flowing through the flow path. The sensors are placed in precise locations using various approaches that make manufacturing of the cartridge efficient and repeatable. A drain line that is susceptible to fouling may be preattached and various approaches are used to remove or reduce the fouling. An elastomeric contact can also be present in the medical preparation system and used in a conductivity measurement subsystem.

A system for agricultural irrigation water oxygenation for enriching soil oxygen level comprises a source of compressed oxygen (and not compressed air) coupled to a water line feeding an irrigation system, such as a drip irrigation system. The coupling system may include a pressure sensor for measuring the pressure in the water line, a solenoid safety valve, a control valve, a flow meter and a controller that controls the flow of oxygen from the source of compressed liquid oxygen to the water line using the components of the coupling system, without using a special cavitation valve and using off-the-shelf components while achieving the same benefits as a system incorporating the special cavitation valve.

A chemical liquid dilution system includes a first material offering device providing fluid, a second material offering device, and a mixing device. The second material offering device provides liquid. The mixing device includes a fluid mixer, a first connection port, a second connection port, and an output port. The fluid mixer has a fluid limiting channel with an interface communicating with the first connection port and another interface communicating with the second connection port and the output port. The first connection port is connected to the first material offering device. The second connection port is connected to the second material offering device. After the fluid passes through the first connection port and the fluid limiting channel, the fluid and liquid are mixed up to form a diluted chemical liquid, and the output port discharges the diluted chemical liquid. A chemical liquid dilution method is also disclosed.

A fluid dilution control system includes a processor and a plurality of sensors communicatively coupled to the processor. Each of the plurality of sensors is configured to sense a tracer component in a mixed solution of solution and motive fluid, where the tracer component is present in a pre-defined amount in the solution prior to being mixed with the motive fluid in the mixed solution. Each of the plurality of sensors senses a level of the tracer component present in the mixed solution and transmits the sensed information to the processor such that the processor compares the sensed level of each tracer component to a target level of a respective tracer component and causes a rate of dilution of one or more solutions containing the sensed tracer component to be adjusted to reach the target level of the respective tracer component.

A water bottle system for adding an additive, which may be flavoring, to the line of flow without contaminating the main reservoir. The system may include a water bottle with a lid feature that may maintain a flavor that may be infused into the water within the water bottle. The infusion of the additive may be adjusted by a user to have the desired concentration of additive to a user’s liking. The additive cartridge may be reusable or disposable depending on a user's preference.

A dispensing system includes a container containing a flowable base formulation to be dispensed, an additive mixing device, and an actuable pump engine which draws the flowable base formulation from the container and pumps it through the mixing device. The additive mixing device includes a body with an internal cavity, an additive ingredient within the cavity, and a flow path/mixing chamber between an input and an output. With each pump of the device the additive ingredient is introduced into, and mixed with, a flow of the base formulation traveling through the mixing device. Multiple additive mixing devices may be interchangeable for different formulations, and the mixing devices may be refillable.
