Recalculation of a rotameter calibration characteristics

The main provisions of the proposed method of recalculating the calibration characteristics of a liquid rotameter based on numerical modeling of its operation are presented. Modeling was performed using the finite element method with the ANSYS 5.6 software package. Calculations were carried out for water as a calibration liquid and a working liquid with physical properties different from water. Comparative analysis of flow rates for both water and working liquid with the data of the current method confirmed their convergence, which is sufficient for metrological calculations. The method was brought to an engineering form. The results of the work can be used for any type of constant differential pressure flow meters.
