The swirl flow meter, also known as a vortex flow meter or a spiral flow meter, is a type of flow meter that uses the principle of the Karman vortex street to measure the flow rate of a fluid.
The swirl flow meter works by creating a series of vortices in the fluid as it flows through a specially designed meter body. These vortices are generated by a bluff body, which is a small obstruction located in the flow path. As the fluid flows past the bluff body, it creates alternating vortices that are shed downstream of the bluff body at a frequency proportional to the flow rate.
The frequency of the vortex shedding is detected by a sensor, such as a piezoelectric crystal, and is used to calculate the flow rate using the swirl flow meter equation.
Swirl flow meters are commonly used in a variety of industries, including oil and gas, chemical processing, and water treatment. They are particularly useful for measuring the flow of fluids with high viscosity or suspended solids, as they are less likely to become clogged or fouled than other types of flow meters.
One of the key advantages of swirl flow meters is their high accuracy and repeatability, which allows for precise measurement of flow rates over a wide range of conditions. They are also highly reliable and require little maintenance, making them an ideal choice for applications where uptime is critical.
