Simply hold the FloRite® in the air stream or in an open area or against the face of a flat-surfaced register, so that air current is flowing directly into the instrument. No stop watch, curves or calculations of any kind are necessary. Instantaneous, direct readings of air velocity without timing or calculations. Scale lock holds readings until lock is released. Chart converts air velocity readings to cubic feet per minute without calculations.
