Calibrating Thermal Mass Flowmeters

摘要

Proper calibration ensures new and old instruments deliver reliable results. Instrument calibration should never be taken for granted, and thermal mass flowmeters are no exception. Flowmeters can be built with the highest safety ratings, features, and functions and the most industrially robust sensor technology, and still deliver unsatisfactory performance. This happens if the calibration is inaccurate or subject to uncertainty due to an equivalency-based calibration or simulation methods rather than an "actual" fluid calibration.
