A Hot-Wire Anemometer For Particle Counters, Nicholas H. Terrell

Boise State University Theses and Dissertations

Portable real-time air quality monitoring is becoming a reality. While the data quality of these devices may be questionable, they have shown to be promising. One such device is the optical particle counter. The particle counter functions by having laminar airflow with constant velocity traverse the path of a laser beam within an airflow channel. This thesis presents the design and integration of a hot-wire anemometer into the flow channel. The addition of an anemometer allows for real-time airflow velocity measurements to be performed and adjusted. Data from the anemometer can also be used to directly offset irregularities in particulate …
