A device measuring the difference between the incoming fluid flow temperature and the temperature of artificially heated fluid (see Fig. 1).

| Fig. 1. Thermoanemometer sensor schematic . |
The temperature difference is related to thermal properties of fluid () and flow velocity
:
\Delta T = \frac{q \, r}{\lambda}\frac{1}{\rm Nu} |
The calibration plot is usually set in coordinates or in cae of a small velocity range in
coordinates.
