FIELD: measuring equipment.
SUBSTANCE: method of measuring the level of a substance in a vessel, in which its surface is probed by frequency-modulated electromagnetic waves in a fixed frequency range, receive reflected waves, with frequency modulation dividing a fixed frequency band by at least two subbands, and frequency modulation is performed in all subbands simultaneously, and determine the number of excited types of electromagnetic oscillations, characterized in that the sounding of the surface of matter by electromagnetic waves is carried out along the normal to it, in each of the subbands are formed from probing and reflected electromagnetic waves after their repeated successive sounding and reflection from the surface of the matter standing electromagnetic waves and judging the level of the substance according to the number of the types of excited electromagnetic waves corresponding to them during the deviation of the frequency in the resulting resonator.
EFFECT: higher processing speed and accuracy of the measurement procedure.
