IN-FLOW 'High-Flow'F-106EI

Industrial Style Gas Mass Flow Meters for high flow rates

Bronkhorst® model F-106EI Mass Flow Meters (MFMs) are suited for precise measurement of flow ranges between 8…400 m3n/h and 80…4000 m3n/h at operating pressures up to 40 bar. The MFM consists of a thermal mass flow sensor and 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. The IN-FLOW model is of rugged design (IP65) for use in industrial environments or even Zone 2 hazardous areas, with optional ATEX Cat. 3 approval.

IN-FLOW series are equipped with a digital pc-board, offering high accuracy, excellent temperature stability and fast response. The main digital pc-board contains all of the general functions needed for measurement and control. In addition to the standard RS232 output the instruments also offer analog I/O. As an option, an on-board interface can be mounted to provide DeviceNet™, PROFIBUS DP, Modbus or FLOW-BUS protocols.
