How does a hot wire anemometer work

WebThis heat transfer leads to a change in the ohmic resistance of the wire, which is detected by an electrical circuit and related to the flow velocity. Generally, hot-wire anemometry is divided into two circuit variants: Constant Current Anemometer (CCA) and Constant Temperature Anemometer (CTA). The CTA is used on the TFD. WebA hot wire anemometer works by heating through a constant current. As the movement of air passes over wire it has a cooling effect, it’s then this changing of temperature on the …
