One link of the three-link phasing RC chain includes the upper plate of the central capacitor with an external resistance, and the other two links include the upper plates of the capacitors arranged uniformly symmetrically along one axis, connected in parallel, and external resistances. The mass of the liquid is determined accounting for the shape of the inner cavity of the reservoir, and the calculations are adjusted depending on the temperature, permittivity and density of the liquid. The program of the microcontroller included in the apparatus is equipped with a graduated characteristic of the dependence of frequency on the mass of the liquid, accounting for the shape of the inner cavity of the reservoir, as well as an adjustment of the calculations of level and mass from the sensors of the temperature, permittivity and density of the liquid, supplied to the input thereof.
