Commonly Used Sensors: ▪ A fine wire is electrically heated to some temperature
above the ambient.
▪ The wire is cooled by the air flowing past it.
▪ Measuring resistance of the wire provides this
temperature indirectly.
▪ A relationship can be obtained between the resistance
of the wire and the flow speed.
