mini CORI-FLOW Ex dXM12

Ex-proof Coriolis Mass Flow Meters/Controllers for low flow rates

mini CORI-FLOW Ex d Mass Flow Meters are precise and compact instruments for low flow rates, based on the Coriolis measuring principle, built in an explosion proof housing for use in IECEx and ATEX Zone 1 hazardous areas, ATEX approval II 2 G Ex d e IIB T6 Gb. Bronkhorst® model XM12 Mass Flow Meter (MFM) is suited for highly accurate measurement of gas or liquid flow ranges between 0,1…5 g/h and 2…200 g/h (which corresponds with 1,33 …66,6 mln/min up to 0,03…2,66 ln/min when used on nitrogen) at operating pressures up to 138 bar (a).

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.
