Abstract: This article analyzes the ways to improve the quality factor for the single-pipe resonators of vibrating densitometers of oil. An analytic expression relating the amount of reactive efforts to secure the cavity field with its parameters is derived. The condition of the options of homogeneous tubular resonator with high Q-factor is determined. The methods of calculating the non-uniform high quality factor of the resonator tube is considered. The results of the experimental study of the non-uniform resonator tube, manufactured using the proposed methodology, are given.
