METHOD FOR DETERMINING LOCAL CHANGES OF ADMIXTURE CONCENTRATION IN FLUID FLOW

摘要

FIELD: measurement equipment.SUBSTANCE: use: to measure change in the local concentration of impurities in the liquid flow at the entrance to the measuring cell. The substance is that the first change of impurity concentration is determined in time within the measurement cell to the fluid containing an impurity, wherein the concentration changes with time at the entrance of the measuring cell is known, and they find the impulse response of the measuring cell using the deconvolution method. Then they determine the change in the impurity concentration within the measuring cell for the sample liquid with an unknown impurity concentration at the entrance. They calculate the unknown concentration of impurities upon entering the measuring cell using the found impulse response of the measuring cell and a definite change in the impurity concentration inside the cell.EFFECT: improving the accuracy of determining concentration of impurities without changing configuration of a measuring cell.8 cl, 5 dwg
