Product Description
High Sensitivity Vortex Flow Meter
The vortex flow meter operates on the Karman vortex principle to provide accurate measurement and metering of gases, vapors, and liquids. This advanced flow sensor delivers high precision with a wide range ratio, ensuring reliable performance across various industrial applications.
Key Features & Benefits
- High precision measurement with wide range ratio capabilities
- No moving parts for enhanced mechanical stability and reduced maintenance
- Minimal impact from temperature, pressure, and medium composition variations
- Compact design suitable for DN250-300 pipeline installations
- High-sensitivity sensor detects vortex counts with exceptional accuracy
Operating Principle
When fluid passes a triangular column vortex generator, it produces alternating Karman vortices on both sides. These vortices are arranged asymmetrically downstream, and the high-sensitivity sensor precisely counts the vortex frequency. Within specific ranges, the vortex count is directly proportional to flow rate, enabling precise flow calculations through advanced processing.
