Shanghai Yichuan Spiral Vortex Flow MeterIt is a flow measurement device designed based on the principle of vortex generator, mainly used to measure the flow velocity and flow rate of gases or liquids. Its working principle is based on the Karman vortex street theory, which places a non streamlined obstacle (vortex generator) in the direction of fluid flow. When the fluid passes around the obstacle, a series of vortices are alternately generated at its rear. By detecting the frequency of these vortices, the flow velocity and flow rate of the fluid can be calculated.

The characteristics of the vortex flowmeter include:

High precision: able to provide accurate measurements over a wide range of flow rates.

No moving parts: Due to the absence of moving parts, the need for wear and maintenance is reduced.

Suitable for multiple media: can be used to measure gases, vapors, and different types of liquids.

Easy installation: Usually does not require a straight pipe section, suitable for applications with limited space.

Strong anti-interference ability: able to effectively resist the influence of vibration and other external factors.

Shanghai Yichuan and other instrument manufacturers also produce this type of flowmeter and provide various models and specifications of products according to different application scenarios. For example, some models may be particularly suitable for high-temperature and high-pressure environments, while others may focus more on improving measurement accuracy or reducing the minimum measurable flow range and other characteristics.
