Abstract
The present invention relates to apparatuses, systems, and methods that manage the flow of fluids, such as, for example, water, through pipes. Specifically, the apparatuses of the present invention creates a backward pressure in fluid traversing a pipe when the fluid meets a spring loaded poppet valve, wherein the backward pressure within the pipe provides compression to the fluid effectively compressing entrapped gas bubbles within the fluid. The pressure in front of the poppet valve builds and moves the poppet valve away from a seat allowing the fluid with compressed gas bubbles to flow therefrom, which provides more accurate water meter measurements because less gas is being considered in said measurements. Moreover, the apparatuses of the present invention provide backflow prevention. Systems and methods for managing fluids are further provided.
