On the Correction Factor for Calibration of the Flowemeters with Axial Turbine

Abstract

This paper refers to axial turbine flowmeters used for technical measurements of volumetric flows at hydraulic driving systems. This study demonstrates that volumetric flow through the transducer has proportional value with the angular speed of turbine, and the proportionality factor the depends on constructive parameters and on hydraulic agent characteristics. The proportionality parameter was introduced as a calibration factor of the apparatus with respect to the transducer type which was used for measurement. This paper is useful for designing and developing this kind of apparatus, for measurement activities that involve flowmeters, and for those who analyze the basic principles of flow measurements (researchers, designers, students, etc).
