vortex flow meter for steam,air,gas

Product Details

The vortex flow meter is a highly accurate and reliable instrument used for measuring the flow rate of liquids, gases, and steam. Its operating principle is based on the von Karman effect, which creates alternating vortices when a fluid flows past a bluff body, such as a circular cylinder. These vortices produce pressure fluctuations, which can be measured to determine the flow rate.

The vortex flow meter consists of a bluff body, typically in the shape of a triangular or rectangular prism, placed in the flow stream. As fluid flows past the bluff body, vortices are shed alternately on each side of the body. These vortices create a frequency that is proportional to the fluid velocity. The frequency is detected by a piezoelectric crystal or a pressure sensor, which converts the frequency into an electrical signal that is proportional to the flow rate.

Vortex flow meters are highly versatile instruments that can be used to measure the flow of fluids in a wide range of industries, including oil and gas, chemical processing, power generation, and water treatment. They are particularly well-suited for applications that involve high temperatures, high pressures, or corrosive fluids. Additionally, vortex flow meters require very little maintenance and have a long service life, making them a cost-effective choice for flow measurement.

Overall, a vortex flow meter is a robust and reliable instrument that provides accurate and precise flow measurements, making it an indispensable tool in many industries.
