Certain embodiments of the present disclosure are directed to a method that may include identifying at least one metric for a fluid flowing through a line from a vessel to a dispenser. The method may include identifying a reference value for the at least one metric for the fluid. The method may include performing an analysis of the fluid based on the at least one metric for the fluid. The method may include comparing results of the analysis with the reference value. The method may include performing at least one action based on determining that there has been a change in the at least one metric relative to the reference value.

An adapter for an airtight connection to a container and for airtight dispensing of the container's contents, the adapter having: a gate valve, a tube extending from the gate valve to a female coupling, the female coupling being configured for insertion in a mouth of the container, the female coupling having a dispensing valve for opening when dispensing the container's contents and closing when dispensing is finished as needed, such that air is prevented from entering the container, and an airtight connector for connecting the adapter to the container.

A self-propelling container having: a top; a bottom; a plurality of vertical walls extending between the bottom and the top; an inner bag for holding contents to be dispensed; a female coupling configured to receive and establish a friction seal with a male coupling of an external device for inserting or extracting the contents to or from the container after the friction seal is established between the female and male couplings; and at least one independent panel positioned inside the container; a compressible element associated with the at least one independent panel wherein during filling of the inner bag the compressible element is compressed, thus causing the at least one independent panel to exercise pressure onto the inner bag, and thus, helping to empty the inner bag.

A variable-flow beer faucet mechanism includes a housing including a flow-through valve, a beer inlet mechanism fluid coupled to the flow-through valve, a beer outlet mechanism fluid coupled to the flow-through valve, and a variable-flow activation handle coupled to the flow-through valve, the handle being mounted for limited rotational movement in 360 degrees with the amount of movement determining the flow.

Described herein are various embodiments of systems, devices, components and methods for providing hydration to a user from a fluid reservoir or bladder, where the fluid is provided on demand by the user activating and controlling a user interface that communicates wirelessly with a control assembly operably connected to a pump and the fluid reservoir.
