Calibration of Bell Prover Test Stands with Critical Flow Venturi Nozzle

Jakub Wildner , Mateusz Turkowski , Maciej Szudarek , Arkadiusz Zadworny


Bell provers are common calibration laboratory standards for the unit of gas volume and volume flow rate. The article presents a method of bell prover calibration. It bases on Critical Flow Venturi Nozzles (CFVNs) as transfer standards. The study has shown that calibration of a bell prover using proposed method gives comparable results to the other methods at lower costs, especially calibration time was greatly reduced. In the entire calibration curve the uncertainty did not exceed 0.2% at the confidence level of 95%. Uncertainty analysis is presented. Additional advantage is the possibility to determine displaced volumes for small doses.
