Turbine flowmeter calibration parameter obtaining method applied to real medium

The invention relates to a turbine flowmeter calibration method, in particular to a turbine flowmeter calibration parameter obtaining method applied to a real medium. The turbine flowmeter calibration method solves the technical problems that an existing turbine flowmeter calibration method used in the real medium environment has deviation, accurate turbine flowmeter calibration parameter indexes are difficult to obtain, and measurement data of a turbine flowmeter are not accurate. The invention discloses a turbine flowmeter calibration method applied to a real medium. The turbine flowmeter calibration method comprises the following steps: step 1) obtaining a volume flow value of a liquid oxygen container; 2) establishing a calibration system according to a dynamic volume method principle; 3) determining a calibration flow point of a liquid discharge test; 4) performing a liquid pre-discharge test and a liquid discharge calibration test of all calibration flow points, and recording and storing all effective c
