Abstract. The article is focused on creating high-precision measurement assurance of volume and volumetric gas flowrate measurement, in particular the bell provers. The analysis of key factors influencing the measurement accuracy and realization of gas flowrate and assessment of the impact of pressure fluctuations under gauging tank space of metrological plant of bell prover type was conducted. The practical solutions for accuracy increasing of bell prover by ensuring of pressure quasi stability under gauging tank by using servo drive for gauging tank control movement has been suggested. It is minimizes the transient process duration and allows optimal using of interior volume for realization of volume and volumetric gas flowrate.
