Vintage Taylor Instruments anemometer, a mechanical device used to measure wind or airflow velocity, often in feet per minute.
Function: It works as a rotating vane anemometer; the airflow causes the vanes to spin, and the device registers the total distance of air movement over a set period, which is then used to calculate velocity.
Design: This specific model is a "Biram" style anemometer, where the dials and vanes are on the same plane.
Included Accessories: The image shows the device alongside its original instructions and a correction chart, which was commonly used with these vintage instruments to ensure accurate readings.
Usage: Historically, these instruments were frequently employed in mining, ventilation surveys, and scientific applications to measure air flow in enclosed spaces.
