The hot film anemometer (HFA) is made of a thin, structured, metallic resistive film (“heater”) which is deposited onto a substrate. In the operating state of the HFA the electrical power heats the heater up to a certain temperature. An air-flow of ambient temperature cools the heater down until equilibrium between the electrical Joule heat and the thermal heat loss is reached.Read more
