Tips: Hot wire anemometer working principle
It places an electrically heated thin metal wire (hot wire) in the airflow, the heat dissipation of the hot wire in the airflow is related to the flow rate, and the heat dissipation causes the temperature change of the hot wire and causes a change in resistance, and the flow rate signal is converted into an electrical signal. The above is the working principle of a hot wire anemometer.
