EL-FLOW Base F-201CB

Gas Mass Flow Controllers for OEM Applications

Bronkhorst^® EL-FLOW^® Base model F-201CB Mass Flow Controllers (MFCs) are standard and straightforard instruments suited for precise measurement and control of flow ranges between 0,16…8 ml_n/min and 0,4…20 l_n/min at operating pressures between vacuum and 10 bar(g). EL-FLOW^® Base instruments are equipped with a digital pc-board, offering high accuracy, excellent temperature stability and fast response. In addition to the standard analog I/O the MFCs also offer RS232 or Modbus-RTU or -ASCII communication.

EL-FLOW^® Base is an economical solution for installation in (OEM) systems e.g. in coating or welding applications.
