Best Practices: Safety And Certainty With Actual Gas Calibration Of Thermal Mass Flow Meters

Flow meter calibration should never be taken for granted, and thermal mass flow meters are no exception. Flow meters can be built with the highest safety ratings, features and functions, and the most industrially robust sensor technology, but if the calibration is inaccurate or subject to uncertainty due to an equivalency-based calibration or simulation methods rather than an "actual" fluid calibration, then the device could produce unsatisfactory performance issues.

The results of poor calibration practices can include possible safety exposures and process inefficiencies that might go undetected until the process is running and something goes wrong. Inefficient processes also frequently result in poor product quality and excessive costs which negatively impact the bottom line and competitiveness.
