Abstract

The article is focused the analytical tasks that describe the most typical cases of using of the heat flow sensor to control the heat losses on various types objects. Recommendations to improve the accuracy of measurement of surface heat flow density depending on the heat transfer characteristics of an object-to-be-controlled.
