mini CORI-FLOW™MI130

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

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 MI130 Mass Flow Meter (MFM) is suited for highly accurate measurement of gas or liquid flow ranges between 1…50 g/h and 20…2000 g/h (which corresponds with 13,3…666 mln/min up to 0,26…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 instrument contains a microprocessor based pc-board with signal and fieldbus conversion and a PID controller for optional mass flow control by means of a separately mounted control valve or pump.
