The paper presents the research results to increase the probability of mass fractions measuring control of liquefied petroleum gas components, which has various temperatures by defining the density of the liquid phase. The thermooptical method for measuring control of mass fractions of liquefied petroleum gas components is presented in the paper. The measuring conversion function of the refractive index of liquefied petroleum gas was improved based on the proposed method. Based on research conducted it was developed the device of optoelectronic mass fraction measuring of liquefied petroleum gas components. The estimation of static metrological characteristics of control device measuring channel for the liquefied petroleum gas components mass fractions. The control device basic errors are defined as well.
