The purpose of this study is to improve the power generation efficiency of the self-powered turbine flowmeter developed by the authors. To increase the efficiency, the NACA airfoil was applied to the blade of the rotor. It was shown that the efficiency is favorably improved over the entire range of the flowrate by using the NACA airfoil blade.
