CORI-FLOW™M54

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

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 M54 Mass Flow Meter (MFM) is suited for highly accurate measurement of gas or liquid flow in the range of 0…100 kg/h (which corresponds with 0…1333 ln/min when used on nitrogen) at operating pressures up to 200 bar. 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.
