[0019] Specifically, the high-efficiency condenser 12 is fixedly installed on the surface of the high-efficiency cooling fan 13; the air titration tube 14 and the first electromagnetic valve 15 are connected through pipelines; the first pressure differential sensor 16 is connected with the air titration tube 14 and the first electromagnetic valve 15 through pipelines; the second electromagnetic valve 19 is fixedly installed on the output end of the condensate water titration tube 18; the output end of the air titration tube 14 is connected with the condensate water titration tube 18 through pipelines; and the second pressure differential sensor 17 is connected with one end of the condensate water titration tube 18.

[0020] Working principle: the inlet of the steam four-way pipeline 6 needs to be connected with a pressure-resistant pipeline of a to-be-measured steam pipeline, which functions to guide the high-pressure steam in the to-be-measured pipeline out and detect the pressure by the first pressure transmitter 7; the drain valve 8 drains the steam condensate water in the steam four-way pipeline 6; the steam four-way pipeline 6 and the measurement four-way pipeline 9 have a pressure relief hole, and the high-pressure saturated steam is discharged to the measurement four-way pipeline 9 through the pressure relief hole; when the measurement four-way pipeline 9 receives the pressure relief steam, the second pressure transmitter 10 and the temperature sensor 11 measure the pressure and temperature of the pressure relief steam, and then calculate the specific enthalpy of the pressure relief steam, and then, in combination with the pressure value measured by the first pressure transmitter 7, the superheat degree and the dryness of the to-be-measured steam can be calculated.
