A procedure for indirect measurement according to arguments that are random variables can be regarded as a process of transformation of these variables by a zero-lag nonlinear element. The probability characteristics of the result that are obtained at the output of the element in this case determine the error of indirect measurement. The indicated transformation procedure can be solved, e.g. by analytical methods. However, these methods for the analysis of the errors of computations of complex functions of many variables are exceedingly time-consuming. On the other hand, the classical method of estimating the errors of indirect measurements by expansion of the primary function in a Taylor series for large mean-square values is inefficient. Simulation modeling has been proposed in order to overcome the indicated difficulties. The author discusses the determination of the characteristics of the error of measurement of the heat-transfer coefficient k of a coolant oil in a gas-transport system (GTS), determined on an IVK-7 apparatus, along with the total error of one of the channels.
