FF-C1xD

Downported Mass Flow / Pressure Controllers

FLEXI-FLOW Compact models FF-C10D and FF-C11D Downported Mass Flow / Pressure Controllers are suited for accurate measurement and control of flow ranges between 0…500 ml_n/min and 0…20 l_n/min at operating pressures between 0,8 and 17 bar(a). The instrument combines a swift and stable thermal mass flow sensor based on capillary MEMS technology with a precise and proven by-pass construction. Due to the unique, internationally patented TCS Technology (Through Chip Sensor), accurate mass flow measurement, virtual independent of variations in temperature and line pressure is established. In combination with integrated temperature and up- and downstream pressure sensors, the embedded database for 22 gases allows accurate, on-board conversion. The multi-parameter instruments provide the user with useful process information.

FF-C1xD FLEXI-FLOW Compact Downported Mass Flow / Pressure Controllers feature a turndown to 1:1000 and a free selection of ranges between 0,5 and 20 l_n/min (FS, based on N₂). The instruments are Built-to-Order and are currently available in 2 variants:

Type FF-C10D: flow + temperature
Type FF-C11D: flow + temperature + up- and downstream pressure
