EL-FLOW® Base - Laboratory style
GAS Mass Flow Controllers for OEM Applications


The Mass Flow Controllers of the EL-FLOW® Base series are standard and straightforward instruments. They provide accurate measurement, fast response and stable control in common gas flow applications. EL-FLOW Base is an economical solution for installation in (OEM) systems e.g. in coating or welding applications.

The instruments operate on the principle of thermal mass flow measurement in ranges starting from 0,2…10 mln/min up to 4…200 ln/min air-equivalent. They offer analog I/O-signals as well as digital RS232 communication and/or Modbus-RTU as a standard feature. EL-FLOW Base is a member of Bronkhorst’s most popular and field proven EL-FLOW series.
