Thiết bị điều khiển lưu lượng Coriolis Bronkhorst mini CORI-FLOW™ M12V10I
Thiết bị điều khiển lưu lượng Coriolis lưu lượng thấp cho khí mini CORI-FLOW™ M12V10I Low Flow Coriolis Mass Flow Controller for Gases is 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 M12V10I Mass Flow Controller (MFC) is suited for highly accurate control of gas flow in the range of 0…200 g/h (which corresponds with 0…2,66 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. The instrument contains a microprocessor based pc-board with signal and fieldbus conversion and a PID controller for mass flow control by means of an integrated control valve (normally closed).
