[Applicability of methods for determining air velocity in livestock buildings]

Comparative studies were carried out on the applicability of the katathermometers, mechanical anemometers, and the thermoelectric anemometer type TEA-4, devised by the authors and introduced into practice, for determining the velocity of air in livestock buildings. TEA-4 proved more perspective for measurements in animal breedings as it makes possible a continuous automatic control on air velocity. This, in turn, renders it feasible to follow up the day-and-night and the seasonal dynamics of this microclimate factors. By preciseness and exploitation dependability TEA-4 has proved superior to katathermometers and mechanical anemometers. Its adoption into practice has made it possible to shorten the time of measurement.
