Extensive Mechanical Configurations
GF Series supports all metal seal/UHP industry gas connection interface
standards for full OEM and process coverage.
• Downport 79.8mm and 92mm C-seal and W-seal on 1-1/8" and 1-1/2"
bodies
• 124mm 4 VCR on 1-1/2" body
Enhanced Diagnostics and User Interface
The mass flow controller is one of the most complex and critical
components in gas delivery systems. When dealing with ultra-high-purity
gas distribution or highly toxic or corrosive gases, removing the mass flow
controller to assess functionality should be the last resort. Brooks GF
Series devices provide for in-line device evaluation and instantaneous
troubleshooting through:
• Embedded self test routines and independent diagnostic/service port
• High visibility LCD display with easy accessible push button for local
indication of Flow (%), Temperature (
o C), Pressure (PSIA/kPa) and
Network Address
• Zero button to easily re-zero the device during scheduled maintenance
This combination of features results in limiting service interruption and
reduced downtime.
Communication Interfaces
The GF100 Series supports analog 0-5 Vdc, RS485, and DeviceNet™
communication protocols. Analog connections can be accessed via the
DeviceNet or RS485 or Analog only connector options. DeviceNet and
RS485 are multi-drop connections that allow a maximum of 64 devices for
DeviceNet and 32 devices for RS485 to be connected on the same
network. Brooks Instrument’s DeviceNet profile has been certified by the
ODVA™ (Open DeviceNet Vendor’s Association). A range of low profile
adapter cables facilitate replacing previously installed devices eliminating
the need to carry multiple devices of the same gas/range but different
electrical connectors.
