Chemical tracer method of and structure for determination of instantaneous and total mass and volume fluid flow

摘要

Instantaneous mass flow rate of a component of interest in a flowing fluid is determined by structure for and method of introducing a tracer at a known mass flow rate into the flowing fluid, then analyzing for the concentration of the tracer and that of the component of interest in the mixed flowing fluid, and obtaining the product of the concentration of the component of interest, the reciprocal concentration of the tracer, and the mass flow rate of the tracer. To obtain the total mass flow of the component of interest, the instantaneous mass flow rate is time integrated over the desired period.PPIn addition to obtaining the instantaneous and total mass flow of the component of interest, similar structures and methods are used for obtaining (1) volume flow, (2) mass flow of particulate matter, (3) linear velocity of the flowing fluid or the cross sectional area of the flowing fluid, (4) concentration values of the tracer and the component of interest in the presence of particulate matter by passing three signals through the flowing fluid, and (5) single average concentration values for each component in a collected sample rather than obtaining continuous analysis data during the flow time.PPThe case is considered where the introduced tracer undergoes a reaction when the reaction products are qualitatively and quantitatively analyzable.
