YUNYI Vortex flow meters are volumetric flow meters designed based on the “Karman vortex street” principle. When a fluid flows past a non-streamlined obstruction (vortex generator), regular vortices are alternately generated on both sides of the obstruction. The frequency of these released vortices is proportional to the fluid velocity. By precisely detecting the vortex frequency through built-in piezoelectric or capacitive sensors, the instantaneous and cumulative flow rates of the fluid can be calculated. Due to its simple structure, lack of moving parts, high reliability, and wide range of applicable media, it has become the dominant product for measuring the flow of steam, gases, and low-viscosity liquids. Product Advantages The core value of vortex flow meters lies in their perfect balance of reliability, applicability, and cost-effectiveness. 1. No moving parts, high reliability: With no internal impellers or moving components, the robust structure minimizes wear and tear, requires minimal maintenance, ensures long-term stable operation, and offers extended service life. 2. Wide range of applicable media: Accurately measures steam, gases, liquids, and other media. One meter serves multiple purposes, reducing spare part varieties and lowering procurement and management costs. 3. Wide Turndown Ratio for Broad Applicability: Typically offers a turndown ratio of 10:1 or higher, maintaining accuracy under significant flow rate variations to meet production demands from low to full load. 4. High Measurement Accuracy with Stable Output: Achieves accuracy up to ±1.0% R or better. Outputs stable, interference-resistant frequency pulse or standard current signals,
