Abstract: Featured are systems and methods for measuring differential and absolute pressure of a flowing fluid/gas in a fluid system. In such a method the fluid system is configured with first and second pressure taps that are spaced from each so the second pressure tap is downstream of the first pressure tap in a direction of flow. An absolute pressure sense element and a differential pressure sense element are provided, where the absolute pressure sense element is first fluidly coupled to one of the first or second pressure tap to measure an absolute pressure representative of the flowing fluid/gas. The differential pressure sense element is second fluidly coupled to each of the first and second pressure taps so as to measure a differential pressure of the flowing fluid/gas between the first and second pressure taps.

Abstract: The present invention consists of a water or soda bottle or vessel which is designed to allow for the bottle to interconnect with other bottles of similar design and standard dimensions to form useful second use products. A recess in the lower surface of the bottle receives the neck of another storage bottle. There are recesses perpendicular to the vertical axis of the bottle capable of receiving the mating side recess of another storage bottle. There are two such recesses on each storage bottle, one on each side of the bottle, parallel to each other. This allows for a bottle positioned on its side perpendicular to a vertically positioned bottle to be used to connect two vertically perpendicular storage bottles.
