Anemometers
Hot wire anemometers use a very fine wire electrically heated up to some temperature above the ambient. Air flowing past the wire has a cooling effect on the wire. As the electrical resistance of most metals is dependent upon the temperature of the metal, a relationship can be obtained between the resistance of the wire and the flow speed. Because of their high-frequency response and fine spatial resolution, hot-wire anemometers are ideal for the detailed study of turbulent flows, or any flow in which rapid velocity fluctuations are of interest.

Here are a few questions to help prepare for your next anemometer project:
-
Will you need to datalog?
-
Which parameters do you need to monitor?
-
What is the possible range for each parameter?
