A vortex flow meter is a type of flow measurement instrument that uses the principle of the Von Karman vortex street to measure the flow rate of fluids, such as liquids, gases, and steam. It is commonly used in industrial processes and applications where accurate flow measurement is critical. The device typically consists of a bluff body, also known as a shedder bar, mounted in the flow stream. The bluff body causes vortices to form in the fluid as it flows past, which are detected by a sensor or a series of sensors placed downstream. The frequency of the detected vortices is proportional to the flow rate of the fluid, allowing the device to calculate and display the flow rate in real-time. Vortex flow meters are known for their accuracy and reliability, even in harsh environments with high temperatures and pressures. They are also relatively easy to install and require minimal maintenance compared to other types of flow measurement instruments. In addition to measuring flow rate, vortex flow meters can also provide information on fluid temperature, density, and viscosity. Some models may also feature digital displays, analog outputs, and advanced communication protocols, allowing for easy integration with control systems and data acquisition systems. Overall, vortex flow meters are a versatile and dependable solution for measuring fluid flow rates in a wide range of industrial applications, from chemical processing and power generation to water treatment and HVAC systems
