FIELD: measuring equipment.
SUBSTANCE: in the method for determining the interface position between the components of a three-component medium, in which a long line segment is placed vertically in the container with the controlled medium, filled with the medium components according to their location in the container, the medium is probed by the video signals propagating in the long line segment, and the time characteristic of their propagation is calculated, further the electromagnetic oscillations are excited in the long line segment at its resonance frequency, its measurement is carried out, and the position of each interface is determined by the difference values, one of which is proportional to the difference between the value ratio, proportional to the propagation time of the video signals in the presence of the controlled medium in the container at the time of their propagation in the absence of this medium, and one, and another value is proportional to the difference between the value, proportional to the square of the resonant frequency ratio in the absence of the controlled medium to the resonant frequency in the presence of this medium in the container, and one.
EFFECT: simplifying the measurement process and increasing the accuracy.
