Abstract The two evaluation methods for the turbine meter by the use of non-fixed point as master meter, linear interpolated method and curve fitting method were presented in detail. On the base of calibration results of 10 pieces of turbine meters, the uncertainties for each method were calculated. The results showed that, the prediction of the curve fitting agreed very well with the calibration result, and the uncertainty was obviously smaller than that of the linear interpolated method.
