EL-FLOW Select F-202AV

Gas Mass Flow Controllers for medium flow rates

Bronkhorst^® model F-202AV Mass Flow Controllers (MFCs) are suited for accurate measurement and control of flow ranges between 0,8…40 l_n/min and 5…250 l_n/min at operating pressures between vacuum and 64 bar. The MFC consists of a thermal mass flow sensor, a precise control valve and a microprocessor based pc-board with signal and fieldbus conversion. As a function of a setpoint value, the flow controller swiftly adjusts the desired flow rate.

EL-FLOW^® Select 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, EtherCAT^®, PROFINET or FLOW-BUS protocols
