Densitometer calibration method |
摘要 |
A method of calibrating a densitometer to meter two gases of different molecular structures by empirically deriving a hole size function of the indicated error for one gas in the density equation of the other and performing tailored reboring of the hole in a production unit in accordance with the hole size derived from the function by determining the full scale error thereof.
