FIELD: measuring equipment.
SUBSTANCE: invention can be used to measure the amount (volume, mass) of a dielectric liquid in a metallic container of arbitrary configuration regardless of its dielectric constant. In a method for determining the amount of a dielectric liquid in a metal container, in which, in the first measurement cycle, electromagnetic oscillations are excited in series in a fixed frequency range [ƒ1, ƒ2] in the cavity of the tank and count the number N of excited types of oscillations, in addition, in the second measurement cycle, electromagnetic waves of fixed frequency are emitted ƒ, for which the wavelength λ in the free space is less than the characteristic size of the cavity, into the space bounded by the metal shell of the container, the average value of the output of the electromagnetic field power P output from the cavity is measured at the wavelength λ, perform a joint functional transformation of N and P.
EFFECT: technical result is the expansion of the functionality of the measurement method.
