Swirl flowmeters, often referred to as swirl meters or precision vortex flowmeters, operate on the principle of imparting angular momentum to the flowing fluid through a set of stationary blades or swirl vanes. As the fluid passes through these vanes it acquires a swirling motion. These swirls are detected by a sensor, and the frequency of their formation is directly proportional to fluid velocity — allowing the meter to accurately calculate the flow rate.
