NEW DESIGN FOR A TRANSFER STANDARD METHOD FLOW STAND

Dean M. Standiford
Abstract:
In 2000, Micro Motion, Inc. presented a paper at FLOMEKO introducing a new system for calibrating its flow meters referred to as a Transfer Standard Method (TSM) liquid calibration system. The transfer standards for this system are Coriolis reference meters installed in parallel. The stability of the reference meters is one of the largest contributors to the overall measurement uncertainty in this system. To reduce the measurement uncertainty, reference meters are limited in flow range and two reference meters of each size are used as a quality check with one installed upstream of the unit under test (UUT) and the other installed downstream of the UUT. An updated design of the Transfer Standard Method liquid calibration system incorporating reference meters in series was recently built and put into service at Micro Motion. A discussion of the updated design, the quality check data that is inherently built into the updated design and an analysis of these results are presented in this paper.
