Gas Mass Flow Controllers for OEM Applications

Bronkhorst® EL-FLOW® Base model F-201AB Mass Flow Controllers (MFCs) are standard and straightforard instruments suited for precise measurement and control of flow ranges between 0,4…20 ln/min and 1,4…70 ln/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.
