The CI-FT80 and CI-FT80T thermal mass flow meters are advanced instruments engineered for accurate, real-time measurement of standard flow, mass flow, gas consumption, and temperature. Built with an explosion-proof structure certified by national authorities, these meters are ideal for use in demanding industrial environments where safety and performance are paramount.
With cutting-edge full-digital signal processing technology, the CI-FT80 series delivers superior measuring accuracy and a wide turndown ratio of up to 1:2500, outperforming conventional flow meters. It features no moving parts, ensuring excellent long-term stability, vibration resistance, and reliability.
Capable of detecting ultra-low flow rates down to 0.1 Nm/s, the CI-FT80/FT80T is perfectly suited for applications involving volatile flow conditions, low-flow bypasses, or the precise monitoring of gas usage in individual equipment.
Enhanced with intelligent self-diagnostic functionality, these meters can detect sensor contamination in real time and proactively protect against overheating—setting a new benchmark in flow measurement technology.
