Abstract
A new thermistor anemometer is described for measuring low air velocities of 0–100 cm/sec. A theoretical performance curve (anemometer output vs air velocity) was calculated for the instrument. When compared with the experimental performance data, good correlation existed. Several characteristics of the anemometer were investigated experimentally. The instrument displayed excellent sensitivity and good stability (reproducibility of the calibration curve at a given ambient temperature). The output was not affected by the air flow direction. The anemometer output was affected by changes in ambient temperature, and the use of calibration curves for various ambient temperatures is suggested.
