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. Mass Flow Meters: from 0,4 ... 20 m3n/h up to 220 ... 11000 m3n/h. Mass Flow Controllers: from 0,4 ... 20 m3n/h up to 10 ... 500 m3n/h. The control valves are normally closed and available up to Kv-values of 6.0. "Multibus" Digital Mass Flow Meters/Controllers Bronkhorst High-Tech developed their digital instruments according to the flexible "multibus" concept, due to which the instruments can be equipped with on-board interface board with DeviceNetTM, Profibus-DP®, Modbus or FLOW-BUS protocol.
