Compact and competitive Mass Flow Meters for high gas flow rates

For consumption measurement of high gas flow rates, customers often select volumetric flow meters e.g. Vortex flow meters, turbine flow meters or instruments based on the measurement of differential pressure. To read mass flow, all these measurement principles require temperature and pressure compensation. Bronkhorst Series F-106 / F-107 directly measure high mass flow rates of gases up to a pipe size of 10 inch / DN 250. Furthermore their digital pc-board offers counter and alarm functions as a standard feature, as well as the option to integrate an on-board interface board for CANopen®, DeviceNet™, EtherCAT®, PROFIBUS DP, PROFINET, Modbus RTU, ASCII or TCP/IP, EtherNet/IP, POWERLINK or FLOW-BUS communication.

Mass Flow Controllers for high gas flow rates

IN-FLOW 'High-Flow' models F-206AI / F-206BI are compact  Mass Flow Controllers with integrated, normally closed control valves with up to Kv-values of 6.0 and flow rates up to approx. 375 m3n/h N2-equivalent. For higher flow ranges Bronkhorst can offer IN-FLOW 'High-Flow' flow meters combined with separate control valves from other manufacturers.

Approvals for hazardous locations

As an option, IN-FLOW Mass Flow Meters and Controllers can be offered use in explosive environments. For the European market, all IN-FLOW instruments can be adapted for application in ATEX Category 3, Zone 2. For the North American market, IN-FLOW devices can be offered with FM Class I Division 2 approval.
