Monitoring changes of integral composition of a substance is based on measuring changes in phase progression of a microwave signal in its multiple distribution through a volume of the controlled substance. Each passage of electromagnetic oscillations through the controlled substance is characterized by an artificially introduced frequency shift of the microwave oscillations by a certain value. After homodyne conversion in the microwave mixer of initial microwave oscillations and transformed by frequency oscillations passed through the substance at the output of the mixer there is a series of combination low-frequency difference components, of which one is selected determined by the required ratio of the passage of microwave oscillations through the substance.
