Vortex Flowmeter
The vortex flow meter is a precision instrument designed for measuring the volume and mass flow of liquids, gases, and steam based on the Kármán vortex principle. Utilizing advanced differential algorithms along with isolation measurement, shielding, and wave filtering technologies, vortex flowmeters provide high accuracy while maintaining strong immunity to vibration and noise.
Our LUGB series vortex flow meters feature unique sensor packaging technology, ensuring long-term reliability and stability even in harsh industrial environments. Upon receipt, carefully inspect your vortex flow sensor for visible damage. As a high-precision measuring instrument, it should be handled with care. Remove all protective plugs and caps for thorough inspection, and if any items are damaged or missing, contact us immediately.
Before installation, confirm that the vortex flow meter model meets your specific application requirements, whether it is for measuring water, steam, gas, or other industrial fluids. Our industrial vortex flowmeters are suitable for a wide range of applications, including chemical, petrochemical, HVAC, water treatment, and energy management systems.
