Brooks® GF40 (elastomer seal) thermal mass flow controller (MFC) and thermal mass flow
meter (MFM) achieves unprecedented performance, reliability, and flexibility in many gas
flow measurement and control applications.
At the heart of the GF40 is Brooks’ patented 4th generation MultiFloTM capable device.
MultiFlo overcomes a long-standing limitation of many thermal MFCs – when changing
gas types, a simple correction factor, such as the ratio of heat capacities between the
calibration gas and new gas, cannot account for accuracy-robbing viscosity and density
differences. The Brooks MultiFlo database is built on thousands of native gas runs to
establish correction functions that account for both thermal and physical differences
among gases making the GF40 Series among the most accurate and flexible MFCs/MFMs
available today.
The Brooks GF40 Series is the perfect choice for customers who use thermal mass flow
controllers or thermal mass flow meters on a variety of gases, who need to change gas
type frequently, or who need to re-range while preserving gas measurement and control
accuracy. Some examples:
• OEMs will reduce the number of gas and range-specific MFCs that they inventory
• Solar, biotech, CVD, plasma, glass, web coating, nanotechnology, vacuum processing
and similar large users of mass flow meters and mass flow controllers will greatly
reduce their gas- and range-specific spares inventory
• R&D, research, and laboratory users can quickly change experiment conditions and
achieve much better actual process gas accuracy vs. traditional mass flow devices
MultiFlo programming is simple and fast – a new gas and range can be programmed
under 60 seconds plus the device can be programmed without removing it from service
or disconnecting the device from any process or tool control system.

The Brooks GF40 Series features a corrosion-resistant Hastelloy C-22 sensor for durable,
long-term operation. Sub-1 second settling times and 1% of set point accuracy ensure
that the GF40 will provide reliable flow measurement or flow control in demanding gas
flow applications. The GF40 achieves excellent internal to external leak integrity for
challenging process gases as found in CVD, solar, and other processes. With a wide range
of connector types, seal and seat materials, and digital and analog I/O options available,
the GF40 represents an extremely powerful, yet easy, upgrade for existing MFCs or MFMs.

A major advancement over traditional single point gas
conversion factors, Brooks MultiFlo technology delivers up to a
three-times improvement in process gas accuracy. This is
achieved through advanced gas modeling plus extensive actual
gas testing protocols that provide extremely accurate
compensation. MultiFlo also allows the device to be quickly and
easily configured for another gas and/or flow range without
sacrificing accuracy or range-ability. Selecting a new gas
automatically creates a new calibration curve, establishes
optimized PID settings for dynamic control, compensates for
gas density and viscosity effects, and ensures smooth,
overshoot-free transitions between flow rates with excellent
steady state stability.
Brooks MultiFlo technology offers unparalleled flexibility; a
single device can be configured for thousands of different gas
and flow range configurations.
Re-programming is simple and fast; a new gas and range can
be programmed in under 60 seconds. Brooks provides an
enormous gas database to ensure the maximal value of
MultiFlo is realized:
• Dramatically reduces inventory or spares expense
• The MFC full scale flow range can be scaled down typically by
a factor of 3:1 with no impact on accuracy, turndown or
leak-by specifications for tremendous process flexibility

The mass flow controller remains one of the most complex and
critical component in gas delivery systems; removing the mass
flow controller to determine if it is faulty should be the last
resort. In response to this fact, Brooks pioneered smarter mass
flow controllers with embedded self test routines and
introduced an independent diagnostic/service port to provide
access to diagnostic data for troubleshooting without
interrupting flow controller operation.
• Improved signal to noise performance for improved accuracy
at low setpoints
• Improved reproducibility at elevated temperatures through
new isothermal packaging, onboard conditioning electronics
with ambient temperature sensing and compensation
• Improved long-term stability through an enhanced sensor
manufacturing process
• Optimized temperature profile for gases prone to thermal
decomposition

Brooks Instrument can provide start-up service prior to operation when required. For some process applications, where ISO-9001
Quality Certification is important, it is mandatory to verify and/or (re)calibrate the products periodically. In many cases this service
can be provided under in-situ conditions, and the results will be traceable to the relevant international quality standards.
