0254 Four Channel Power Supply, Readout & Set Point Controller

The 0254 is an innovative, reliable microcomputer-based controller provides power for up to four Brooks Instrument thermal mass flow, Quantim Coriolis mass flow, and/or pressure devices; all in a new compact design. Additionally, the 0254 can be used to generate flow set point commands, display flow rate, totalize flow, for blending multiple flow streams, and more. This fully RoHS compliant device has a very user-friendly operation and is offered with multiple mounting capabilities such as rack mount, panel mount, and table-top mount.

  • Variety of mechanical configurations for users’ specific application (panel, desktop, rack mount)
  • Self-diagnostics on every power-up ensures device is fully functional
  • Totalization can be used for inventory management
  • Batch control allows single or multi-channel batch recipes
  • Blending supports master slave blending configuration and operation
  • Gas factor scaling adapts 0254 to any non-calibrated fluid
  • Valve Override Control (VOR) – open, closed or normal
  • Large, graphic, high-contrast, eight (8) line backlit display
  • Brooks Smart DDE Software simplifies data exchange between the 0254 and commonly used programs such as Microsoft® Excel, Test Point™ and LabVIEW™
  • RS232 serial port allows remote control, data logging, and remote alarms


  • Valve open (using VOR) allows rapid purge or chamber flooding
  • Easy-to-read display shows all process variables and setpoints for quick reading and adjustment
