Vortex steam flowmeter is one of the main flowmeter products, widely used in petroleum, chemical industry, metallurgy, heating and other departments. Test and measure the flow of liquid, gas and steam.

Vortex flowmeter is widely used because of its wide range, small pressure loss, medium accuracy, linear output, no moving parts, high reliability, small maintenance, medium low price, relatively high performance and price characteristics.

Reliability is a hallmark of vortex flow meters, as they exhibit robust performance in harsh operating conditions. Their simple yet sturdy design, often featuring no moving parts, results in minimal maintenance requirements and increased longevity. This reliability is particularly crucial in industries where consistent and accurate flow measurement is essential for process control and optimization.

vortex flow meter is a specialized instrument designed for measuring the flow rate of liquids, gases, or steam in various industrial processes. It operates on the principle of the Von Kármán effect, where a bluff body (typically a shedder bar or a blunt object) is placed in the flow stream. As the fluid passes by the bluff body, vortices are formed alternately on either side, creating a pattern. The frequency of these vortices is directly proportional to the velocity of the flowing fluid, allowing the vortex flow meter to accurately determine the flow rate.
