FIELD: measurement technology. SUBSTANCE: invention refers to equipment measuring temperature, moisture content and speed of flow of gases with the help of electric means. Device testing parameters of heat transfer agent has hollow axle, temperature and moisture content sensors, tachogenerator, filtering drum and measurement unit. Drum is made of two discs and small-cell gauze. Discs are put on hollow axle with the use bearings. One of discs carries anemometric cups. This disc is connected to tachogenerator. Small-cell gauze is produced from non-wettable material. Sensors and tachogenerator are located inside drum. EFFECT: increased accuracy of test of parameters of heat transfer agent, expanded functional capabilities of device. 1 dwg
