MINI CORI-FLOW™ M15

Model: M15-MAD-33-0-S

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 M15 Mass Flow Meter (MFM) is suited for highly accurate measurement of gas or liquid flow ranges between 0,2…5 kg/h and 3…300 kg/h (which corresponds with 2,67…66,6 ln/min up to 40…4000 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 optional mass flow control by means of a separately mounted control valve or pump.
