Low Flow Coriolis Mass Flow Meters / Controllers for Liquid and Gases

mini CORI-FLOW™ MI-series Mass Flow Meters and Controllers are precise, versatile and compact instruments, based on the Coriolis measuring principle, featuring fast response and designed to cover the needs of the low flow market. Bronkhorst® model MI130 Mass Flow Meter (MFM) is suited for highly accurate measurement of gas or liquid flow ranges up to 2000 g/h (which corresponds 26,6 ln/min when used on nitrogen) at operating pressures up to 200 bar. The instruments are equipped with a robust IP66/IP67 weatherproof housing with screw terminal connections. The MI-series MkII are suitable for an industrial area up to pollution degree 3 with additional gas or dust (Ex) atmosphere (zone 2/22 or EPL Gc/Dc).

The instrument contains smart electronics, featuring alarm and counter functions, and a PID controller for optional mass flow control by means of a separately mounted control valve or pump. With regard to connectivity, the instruments can be equipped with a wide range of fieldbus options, beside their standard analog and RS232 I/O communication.
