Abstract: A high accuracy, flowmeter calibration transfer standard with an airflow range of 0.0182 (hereafter noted as 1.82E-02) to 18 kg/s (0.04 to 40 Ibm/sec) is described. The transfer standard contains 162 critical flow venturi meters that have a common discharge coefficient curve traceable through a Mass-Time calibration system to the U.S.A. National Bureau of Standards. The transfer standard venturi meters have a continuous curvature entrance and are designed to avoid boundary layer t r a n s i t i o n throughout their operating range. The venturi configuration is described and compared to the familiar circular arc configuration of Smith and Matz.(1) Data are presented which substantiate the method used to obtain a common operating curve. Calibration results from the Mass-Time System are presented and discussed. Discharge coefficient uncertainty is estimated to be 0.07% for individual meters and 0.05% for several meters operating in parallel.
