CHEMICAL TRACER METHOD OF AND STRUCTURE FOR DETERMINATION OF INSTANTANEOUS AND TOTAL FLUID FLOW MASS AND VOLUME

摘要

Total mass flow of a fluid component is determined by structure for and the method of inserting a chemical tracer into a flowing fluid at a known mass flow rate, removing a mixed sample of the flowing fluid and tracer, analyzing the concentration of tracer and the concentration of a component of the flowing fluid, the total mass of which is to be determined, determining the ratio of tracer to component of interest, integrating the ratio over a predetermined time and multiplying the result by the mass flow rate of the tracer inserted into the main fluid flow. The total particulate mass flow and total volume flow as well as instantaneous mass, particulate mass and volume flows are determined by similar structures and methods.
