Taking the DN 80 mm gas turbine flowmeter as the research object,experimental research was conducted on the instrument coefficient of the tur-bine flowmeter under different media and pressures,and the metrological performance of the flowmeter was analyzed.The instrument coefficients calibrated with different media have significant differences.To ensure fair trade,flow meters used in the same measurement system should be calibrated using the same medium.
