High Sensitivity DN250-300 Vortex Flow Meter Compact For Accurate Detection
Our DN250-DN300 Vortex Flow Meter is specifically engineered for high-precision measurement in large-diameter industrial pipelines. Despite its large caliber, this high sensitivity sensor features a compact design that allows for easier installation in tight spaces compared to traditional flow meters. Utilizing the Karman vortex principle, it provides accurate detection of steam, compressed air, and large-volume liquids with zero moving parts, ensuring long-term reliability and minimal pressure loss in high-flow applications.
The vortex flowmeter produces a velocity flowmeter based on the Karman vortex principle for measurement and metering of conventional gases, vapors and liquids. The vortex flow sensor has high precision and a wide range ratio. It has no moving parts in use, which can improve mechanical stability and reduce maintenance. Vortex is almost unaffected by the temperature, pressure and composition of the medium when measuring the working volume, so it is convenient for the calibration production of the instrument. Therefore, the vortex flow sensor is widely used in production and life.
When a triangular column type vortex generator is provided in the fluid, regular vortices are alternately generated from both sides of the vortex generator. These vortices are called Karman vortices, and the vortex rows are arranged asymmetrically downstream of the vortex generator. Vortex is produced according to this principle. The vortex is generated by the generating body, and the high-sensitivity sensor detects the number of vortices. The number of vortices generated in a certain range is proportional to the flow rate, so the flow rate can be calculated by a precision processor.
