Problems solved by technology

All of these flow measurement devices are inherently limited in how well they can keep the desired characteristic constant and are limited in measuring all variables, including time intervals
The measurement uncertainty caused by these limitations constitutes a major constraint on the ultimate accuracy of the determined flow rates

Abstract

A reference volume for use with pressure change flow rate measurement apparatus has an internal structure comprising elements with cross section and length comparable to the cross section and length of adjacent interstitial fluid regions. The reference volume may have one or more heat conduction elements exterior to and in good thermal contact with a corrosion resistant material that defines the internal fluid holding region.

Description

[0001] Cross-references to related literature [0002] This application claims U.S. Provisional Patent Application No. 62 / 396,809, filed September 19, 2016, entitled "System and Method for Reference Volumes for Flow Calibration," filed September 19, 2016, and entitled U.S. Provisional Patent Application No. 60 / 396,808 for "Systems, Apparatus, and Methods of Variable Constraint for Flow Measurement," and filed September 19, 2016, entitled "Self-Correcting Pressure-Based Mass Flow Controllers Apparatus and Methods," U.S. Provisional Application No. 62 / 396,807, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure is primarily concerned with determining the flow rate of a fluid by measuring the temperature and pressure of the fluid. As used herein, fluid is meant to include materials that are in the gas phase due to a particular combination of pressure and temperature. The invention relates more particularly to a containment ...
