A simplified analysis of the density effect and the Reynolds-number effect on the performance of a gas turbine flowmeter is presented. The analysis indicates a simple method to determine numerically both the density effect and the Reynolds-number effect by a single calibration of the meter in a convenient gas (air) at any convenient pressure and temperature. Results of the analysis are used to predict meter performance in other gases under other operating conditions. A 6-in. gas turbine meter is used to illustrate the practical application of the analysis.
