The possibility of studying fluxes in gaseous media by using fiber-optic distributed temperature sensors with heating elements is considered. Traditionally gaseous media are studied by point electrical devices, anemometers and thermal anemometers. However study of extended objects permits the negligence of information regarding the temporal relevance and area correlation of the data obtained. The use of an extended distributed fiber-optic sensor in the form of a cable version of a thermal anemometer can increase the efficiency of studying the dynamic characteristics of gaseous media, providing not only extensive spatial coverage of the studied object, but also synchronicity of studying recorded events. This prediction is confirmed by the results of laboratory tests conducted by the authors of the article, which additionally demonstrate the possibility of using various research methods that differ from each other by an interpretative approach.
