摘要：
In-this paper, an improvement of heating method for measuring wetness of the flowing wet steam is developed, the basic principle of the heating method is presented and the mathematical model has been built for analyzing the thermodynamics problems during the process of heating. Moreover, an instrument for measuring wetness of wet steam flow was designed and made out. This instrument has been used for measuring wetness of the wet steam flow at the outlet of the nozzle rig in Thermal Turbine Laboratory, Xi'an Jiaotong University. By analyzing the relative error of the result, it was found that this instrument has fairly high accuracy, it can be used as the prototype of practical instrument and has an important applicable value in engineering.
