Because the calibration factor does not change with time and there are no moving parts that wear, Micro Motion Coriolis meters rarely need to be recalibrated. One can even change process fluid and not need to recalibrate the meter. Some customers choose to prove the meters for ISO traceability or to comply with custody transfer regulations. In addition, regulatory agencies or custody-transfer contracts may require periodic proving of the meter. Many traditional proving methods may be used, including master meters, ball or compact provers. Documented techniques have been developed to assure an accurate and reliable prove.
