A Kind of New Calibration Method for the Volume of Bell Prover
Cui Lishui, Lixu
Abstract:
A new 1 m³ bell prover is developed by flow laboratory in China national institute of metrology. Laser tracker and laser interferometer is applied to measure the volume of the bell prover. The result suggests this kind of geometric method is feasible and the uncertainty of result is less than 0.1%.
