mini CORI-FLOW™ Mass Flow Meters and Controllers are precise and compact instruments, based on the Coriolis measuring principle, designed to cover the needs of the low flow market. Bronkhorst® model M14V10I Mass Flow Controller (MFC) is suited for highly accurate control of gas flow ranges between 0,03…1 kg/h and 0,6…30 kg/h (which corresponds with 0,4…13,3 ln/min up to 8…400 ln/min when used on nitrogen) at operating pressures up to 100 bar (higher on request). The instruments are equipped with a robust IP65 weatherproof housing and are optionally available with ATEX approval for use in Zone 2 hazardous areas.
