hot-wire anemometer



  • An anemometer with a velocity-sensing device consisting of a temperature-sensitive wire resistor connected to an electrical circuit and placed directly in the path of the airflow.


  • An anemometer which measures and indicates wind or air flow speeds by the cooling effect said flow has on a stretched electrically-heated wire. As the intensity of the airflow varies, so does the resistance of the wire. These changes are then correlated to a calibrated scale. For proper readings, the probe must be at a right angle to the flow. Also called thermal anemometer.
