Bronkhorst IN-FLOW mass flow meters

Click2Contact

For the consumption measurement of high gas flow rates, volumetric flow meters are often selected, such as 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. The Bronkhorst IN-FLOW Series F-106 and F-107 directly measure high mass flow rates of gases up to a pipe size of 10″ or DN 250. Their digital electronics offers counter and alarm functions as a standard feature, as well as the option to integrate an onboard interface board for DeviceNet, Profibus DP, Profinet, Modbus or FLOW-BUS communication.

IN-FLOW ‘High-Flow’ models F-206AI and F-206BI are compact mass flow controllers with integrated, normally closed control valves with K_V values up to 6.0 and flow rates up to approx. 375 m³/h N₂-equivalent. For higher flow ranges Bronkhorst can offer IN-FLOW ‘High-Flow’ flow meters combined with separate control valves from other manufacturers.

As an option, IN-FLOW Mass Flow Meters and Controllers can be offered for use in explosive environments. For the European market, all IN-FLOW instruments can be adapted for application in ATEX Category 3, Zone 1. For the North American market, IN-FLOW devices can be offered with FM Class I Division 2 approval.
