Abstract
Apparatuses of the present invention create a backward pressure in fluid traversing a pipe, wherein the backward pressure within the pipe provides compression to the fluid effectively compressing entrapped gas bubbles within the fluid, allowing more accurate water meter measurements. The apparatus comprises a poppet valve having multiple springs to minimize or eliminate spring-binding caused by off-center hydraulic force during use.
