There are two common ways to measure air velocity: by using pressure-based instrumentation or by using temperature-based instrumentation. Before we discuss the different technologies available for measuring velocity pressure, it is important to understand the basics of air velocity. Air velocity is the area of air movement measured in distance traveled relative to time elapsed. It...
