Pneumatic Cylinder

Article is devoted to the issue of selecting a gas representative sample directly of consumer (from low-pressure gas pipelines) as well as conducting representative studies of the natural gas heat combustion by using a direct method with gas calorimeter. Article describes the disadvantages of chromatographic method for determining the heat of gas combustion and indicates the necessity of developing a gas calorimeter. Development of a sampler on the basis of a typical cylinder with the using pneumatic drive of various configurations is proposed. Lack of existing samplers is proved.
