The relevance of the issue of controlling the quality of natural gas, in particular its specific higher and lower calorific value, is currently primarily due to the requirements of the Law of Ukraine, which regulates the introduction of gas volume accounting and calculations in energy units on the natural gas market. The paper presents the results of research on improving the method of express control of the calorific value of natural gas, both higher and lower, that meets the requirements of the Law of Ukraine «On the Natural Gas Market». It is shown that the applied circuit and technical solutions allow significantly increasing the accuracy of measurement, realizing the possibility of measuring not only the lower, but also the higher calorific value of natural gas, as well as expanding the possibilities of using the implemented device in both industrial and domestic conditions. 11 Ref., 9 Fig.
