EL-FLOW Select F-110C

Gas Mass Flow Meters for lowest flow rates

Bronkhorst^® model F-110C Mass Flow Meters (MFMs) are suited for precise measurement of flow ranges between 0,014…0,7 ml_n/min and 0,6…9 ml_n/min at operating pressures between vacuum and 100 bar. The MFM consists of a thermal mass flow sensor and a microprocessor based pc-board with signal and fieldbus conversion and a PID controller for optional mass flow control by means of a separately mounted control valve.

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. The EL-FLOW^® Select design features optional Multi Gas / Multi Range functionality, providing (OEM-) customers with optimal flexibility and process efficiency.
