IN-FLOW 'High-Flow' - Industrial style
(IP65) Mass Flow Meters / Controllers for gases


IN-FLOW Series Thermal Mass Flow Meters/Controllers for high flow rates of clean gases are equipped with a 'industrial style' pc-board housing. Ranges:

Mass Flow Meters: from 0.24 ... 12 scfm up to 120 ... 6,000 scfm
Mass Flow Controllers: from 0.24 ... 12 scfm up to 5.8 ... 290 scfm

The control valves are normally closed and available up to Kv-values of 6.0.

"Multibus" Digital Mass Flow Meters/Controllers

Bronkhorst developed their digital instruments according to the flexible "multibus" concept, due to which the instruments can be equipped with on-board interface board with CANopen®, DeviceNet™, PROFIBUS DP, PROFINET, Modbus or FLOW-BUS protocol.
