Abstract:Based on the principles of Viscous fluid mechanics and the theory of rotor dynamics, the slippages through the clearances ef an oval wheel flowmeter is analyzed, and a theoretical model which can predict the effect of fluid viscosity on the error claracteristics of the meter is developed in this paper. It has been shown that the computed results, by using the model are in a reaconable agreement with the experimental data.
Keywords:Flow mcesurement  Oiai wheel fleuweter  Viscosity effect  Leakage  Measuring error
