Hot-wire anemometers use a heated sensor element to measure wind speed. As wind flows over this sensor, it carries away a certain amount of heat, which is used to calculate wind speed. Traditional vane anemometers, on the other hand, use a mechanically rotating vane to measure wind speed. Hot-wire models are generally more accurate and suitable for applications requiring high precision, while vane types are more economical and portable.
When using an anemometer, avoid aiming the instrument directly into strong or turbulent winds to prevent damaging the sensor element. Ensure that the sensor is clean for accurate readings. Calibration is also crucial, especially when performing critical measurements.
