Thermal mass measurement
Thermal dispersion
A heated cylindrical transducer is cooled by the flowing gas or liquid stream. The power in the transducer is controlled such that the transducer temperature is maintained at a constant differential temperature relative to the medium temperature. The transducer power is proportional to the medium flow speed. |
