针对蒸汽干度、流量的测量问题，提出将两个结构特性不同的V锥测量元件组合在一起，建立双V锥组合体进行测量，并进行了现场试验，利用“双V锥”测量了锅炉排量为15～18 t/h、干度为55%～80%时蒸汽的参数，并对锅炉出口干度进行人工化验，经过对试验数据的详细分析，得出该装置测量蒸汽干度的相对误差都在4%之内、流量的相对误差都在3%之内，测量装置可应用于现场测量。
針對蒸汽榦度、流量的測量問題，提齣將兩箇結構特性不同的V錐測量元件組閤在一起，建立雙V錐組閤體進行測量，併進行瞭現場試驗，利用“雙V錐”測量瞭鍋爐排量為15～18 t/h、榦度為55%～80%時蒸汽的參數，併對鍋爐齣口榦度進行人工化驗，經過對試驗數據的詳細分析，得齣該裝置測量蒸汽榦度的相對誤差都在4%之內、流量的相對誤差都在3%之內，測量裝置可應用于現場測量。

Aiming at the problem of steam dryness and flow measurement, two V-cones with different structure and nature were combined together, and then the double V-cone system was established to carry out the field test. The double V-cone system was used to measure the steam parameters of boiler with capacity of 15 ~18 t/h and the dry degree of 55%~80%. And the steam dryness of boiler outlet was determined by artificial test, and the test data were analyzed in detail. The results show that the relative error of the measuring device is within 4%, the flow error is within 3%, the measuring device can be used in field measurement.
