METHOD FOR DETERMINING AT LEAST ONE PARAMETER THAT REPRESENTS A CHANGE IN A FLUID BY MULTI-POINT NEAR-INFRARED SPECTROSCOPY

摘要

The present invention relates to a method for determining at least one parameter that represents a change in a fluid (F) due to a temperature variation in the fluid, for which the fluid is in a medium (2) that is transparent to the near-infrared field, and multi-point (1) and multi-temperature spectral measurements are performed by near-infrared spectroscopy Next, by multivariate analysis of the measurement, the parameter being sought is deduced. In addition, the invention relates to a method for monitoring and/or controlling a flow of a fluid in a duct by implementing such a method for determining a parameter that represents a change in a fluid.
