Fox Thermal Thermal Mass Flow Meter | Model FT3 Temperature Transmitter
The Fox Model FT3 measures two important process variables with a single instrument, providing isolated 4-20mA and pulse outputs for flow rate, and a 4-20mA pulse output for process gas temperature or a second flow rate output.
Direct mass flow measurement, exceptional low-flow sensitivity, fast response, and low maintenance requirements distinguish the Fox Model FT3. Virtually immune to changes in temperature and pressure, the flow meter delivers repeatable, accurate mass flow measurement under varying loads.
It’s rugged, no- moving-parts design is also ideal for high-vibration industrial environments and enhanced EMI immunity makes it suitable for environments where electric motors, ignitors or dirty power may affect instrument performance.
