Study about an influence of impedance element for dynamic characteristics measurement with oscillatory gas flow generator

In this paper, at first, we consider the tested flow meter as the impedance element including the connected pipe and evaluate the impedance characteristic. And we try to examine the performance of the oscillatory gas flow generator experimentally including the measurement set up condition of the connected pipe and the tested flow meters. Moreover, we will examine the policy how the dynamic characteristic measurement of the tested flow meter is possible in the same condition and will clarify the compensation methods.
