Abstract:
|
The buyer/seller of a commodity in the worldwide market place must be assured of an accurate measurement of the quantity under purchase. For fluids, the quantity bought/sold is most commonly determined by flow measurements. Small errors in flow measurements may have enormous engineering and financial consequences. To assure the accuracy of flow meters, flow standards are established and maintained by National Measurement Institutes (NMIs) in various countries worldwide. NIST's Process Measurements Division is the United States' NMI for water flow. There is need to identify and address all of the relevant issues dealing with both water flow transfer standards and water flow proficiency testing protocol. The resulted protocol includes: 1.) the commonly-employed solo meter test set up has been replaced by a drift-eliminating 2**3 full factorial dual-meter set up; and 2.) the Youden Plot has become a formal part of the protocol to assist in the determination of meter and lab effects. The application of this protocol to a pilot in-house NIST system has already resulted in a significant improvement in insight regarding the relative importance of meter, meter position, and flow rate.
