In-Situ Thermal Flow Meter Calibration Validation


In-situ calibration validation is one of the great benefits of thermal mass flow technology. This video reviews in-situ calibration validation and details how the DrySense sensor stability only found in Sierra thermal flow meters is the only way a calibration validation is actually Valid!

When evaluating thermal mass ­flow meters for in-situ calibration validation capability, beware that sensor drift will create false positives that reduce the reliability of the validation. The assumption by all manufacturers, including Sierra, is that their sensor does not drift. Only with sensor stability, can users truly validate a thermal mass flow sensor’s factory-calibrated accuracy in the field. Assure that your thermal mass flow meter has a drift-free, dry sensor, which has no organics and cements that drift over time.
