The article is devoted to coverage of the new approach in creating of the combined principle bell prover for gas meters calibration. The authors analyzed the main sources of errors for bell provers classical design and developed practical solutions for minimizing measurement uncertainty. Servodrive application for bell motion control for minimize of the transition process and allows to achieve optimum use of interior bell volume for realization of volumetric gas flowrate was suggested. The results of the pressure stability investigations under the bell space as an indicator of the feasibility of combined prover technical implementation given in this article.
