This instrument is employed to determine the velocity of a fluid, typically air or water. It achieves this by measuring the difference between the stagnation pressure (the pressure when the fluid is brought to rest) and the static pressure (the pressure of the fluid in its undisturbed state). This pressure difference, known as the dynamic pressure, is then used in conjunction with fluid density to compute the velocity.
Accurate fluid velocity measurements are crucial in various fields, including aviation, meteorology, and fluid mechanics research. These measurements are used to monitor airspeed in aircraft, assess wind speeds, and analyze fluid flow characteristics in diverse engineering applications. The principle behind this velocity determination has been utilized for decades, providing essential data for safe and efficient operation in many different systems.
