IP66-rated multi-gas, multirange elastomer
sealed 100-250 slm mass flow controller
The I-Series IE250A mass flow controller is elastomer-sealed, multi-gas/multi-range MFC with an IP66-rated enclosure designed for use in harsh industrial environments where resistance to liquid and dust ingress are essential. The IE250A is capable of Full Scale ranges from 100 to 250 slm (N2 equivalent).

The IE250 is available with either analog I/O or digital I/O utilizing the latest control algorithms for fast and repeatable response to set point.

Key features

  • Flow Rates from 100 to 250 slm
  • Seal and valve plug option of Viton, Buna, Neoprene or EPDM
  • 1 to 2 second settling time
  • Standard closed conductance leak rate of less than 1.0% of Full Scale

Fast Settling Times

Settling times of 1 to 2 seconds and set point accuracies below 1% of set point outperform those of other typical high flow mass flow controllers. Precise control is maintained down to 2% of the IE250A configured Full Scale flow range. The multi-gas/multi-range capability, along with tight performance specifications for accuracy, control range, and transient response allow users to minimize inventory of high flow MFC part numbers.

Multi-Gas / Multi-Range Capability

The multi-gas/multi-range feature (along with other custom controls) is accessed through the MFCs embedded diagnostic interface, which requires no special software or hardware to operate. A standard Ethernet cable and JAVA-enabled HTML browser, widely available, are all the tools needed. The critical gas parameters for typical high flow rate gases are already stored on the device. Configuring the device is simply a matter of selecting the gas from a drop down menu and specifying the desired Full Scale flow range. The diagnostic interface also allows the user to perform routine device health checks, plot flow response, and store operating data for offline analysis.
