ABSTRACT:
Apparatus for repeatedly indicating incremental pressure fluctuations and methods employing same are disclosed. A chamber may be sealed at an initial pressure and configured to respond to a pressure difference between the initial pressure and subsequent pressure within a container. The container may be filled via a valve mechanism exhibiting a first operational state that may allow for entry of material into the container while sealing the chamber at the initial pressure of the container as it began to be filled. A movable element communicating with the sealed chamber and the container may respond to a pressure differential therebetween, thus causing an indicator to indicate an incremental pressure fluctuation. The valve mechanism may exhibit a second operating state that may allow for the chamber and container pressures to be substantially equalized.
