CI-FV20x-VS Steam Vortex Flow Meter
The CI-FV20x-VS measures gas, steam, or liquid using the Kármán vortex principle, offering high reliability, simple structure, and strong anti-pollution performance. Built-in temperature and pressure sensors enable real-time mass flow calculation through standard density compensation. Its dual ultra-sensitive vortex sensor detects both flow and interference signals. The advanced algorithm filters out vibration and electromagnetic noise, ensuring accurate readings. Featuring DSA (Digital Spectrum Analysis) technology, it provides a wider turndown ratio, better low-flow detection, and stronger anti-disturbance performance than traditional models. Certified explosion-proof with IP67 protection: Ex db IIC T6 Gb / Ex tb IIIC T80°C Db. A compact and powerful solution for industrial flow monitoring.
