MultiFlo™ Gas and Range Configurability
The Brooks MultiFlo technology delivers exceptional improvement in
process gas accuracy for linear and non-linear gases. This is achieved
through advanced gas modeling and optimized through actual gas testing.
Brooks MultiFlo
TM
allows the device to be quickly and easily configured for
another gas and/or flow range without sacrificing accuracy or rangability.
Selecting a new gas automatically creates a new calibration curve,
establishes optimized PID settings for dynamic control, automatically
compensates for gas density effects, and ensures smooth overshoot-free
transitions between flow rates with excellent steady-state stability. Brooks
MultiFlo technology offers unparalleled flexibility. An extensive gas
database is provided and a single device can be quickly programmed for
thousands of different gas and flow range combinations. Process benefits
achieved include:
Mass flow controller full scale full range can be rescaled down typically
by a factor of 3:1 with no impact on accuracy, turndown or leak by
specifications
Optimum process and inventory flexibility resulting in dramatically
reduced inventory costs
Fewer configurations/bin sizes required to support many different
processes
Less down-time with rapid process recovery

Section 1 Introduction
Enhanced Diagnostics and User Interface
The mass flow controller is typically the most complex and critical
component in a gas delivery system, When dealing with toxic or reactive
gases, removing the MFC to access its functionality should be the last
resort. To address this, Brooks GF Series devices include self-diagnostics
and an independent service port for in-situ device evaluation and
troubleshooting:
Embedded self-test routines at power-up
Independent RS485 service port that can be accessed while the MFC is
in operation for data logging and troubleshooting
A convenient Zero button to enable easy re-zeroing during scheduled
maintenance
Communication Interfaces
The GF40 Series supports 0-5 Vdc, 0-10 V, 4-20 mA, 0-20 mA, RS485,
DeviceNet, EtherCAT, and Profibus communication protocols. DeviceNet,
Profibus, EtherCAT and RS485 are multi-drop connections that allow a
maximum of 64 devices for DeviceNet, 128 devices for Profibus, 32
devices for RS485, and 65,535 devices for EtherCAT to be connected on
the same network.
Brooks Instruments' DeviceNet profile has been certified by the ODVA
(Open DeviceNet Vendor's Association).
Brooks Instrument Profibus interface has been certified by the PNO
(Profibus User Organization).
The Brooks Instrument EtherCAT interface has been successfully tested

Section 2 Installation
2-1 General
This section provides installation instructions for the Brooks GF40 Series
Thermal Mass Flow Devices. The installation process consists of purging
the gas supply line prior to installation, unpacking and inspecting the
device, connecting the device to the gas supply line and testing for leaks.
2-2 Receipt of Equipment
When the equipment is received, the outside packing case should be
checked for damage incurred during shipment. If the packing case is
damaged, the local carrier should be notified at once regarding his liability.
A report should be submitted to the nearest Brooks Instrument location
listed on the Global Service Network page on our website:
BrooksInstrument.com/GlobalSupportCenters
Carefully remove the equipment from the packing case. Make sure spare
parts are not discarded with the packing material. Inspect the contents for
damaged or missing parts.
2-3 Recommended Storage Practice
If intermediate or long-term storage of the device is required, it is
recommended that it be stored in accordance with the following conditions:
Within the original shipping container.
Ambient temperature 21°C (70°F) nominal, 32°C (90°F) maximum,
7°C (45°F) minimum.
Relative humidity 45% nominal, 60% maximum, 25% minimum.
2-4 Return Shipment
Prior to returning any instrument to the factory for any reason, visit our
website for instructions on how to obtain a Return Materials Authorization
Number (RMA #) and complete a Decontamination Statement to
accompany it: BrooksInstrument.com/Service. All instruments returned to
Brooks also require a Material Safety Data Sheet (MSDS) for the fluid(s)
used in the instrument. Failure to provide this information will delay
processing of the instrument.
Instrument must have been purged in accordance with the following:

2-5 Transit Precautions
To safeguard against damage during transit, transport the device to the
installation site in the same container used for transportation from the
factory, if circumstances permit.
2-6 Removal from Storage
Upon removal of the device from storage, a visual inspection should be
conducted to verify its "as-received" condition. If the device has been
subject to storage conditions in excess of those recommended (refer to
"2-3 Recommended Storage Practice"), it should be subjected to a
pneumatic pressure test in accordance with applicable vessel codes. To
maintain a device's clean integrity, this service should be performed by
the factory or one of the certified service centers.
2-7 Gas Connections
Prior to installation, ensure that all piping is clean and free from
obstructions. Install piping in such a manner that permits easy access to
the device if removal becomes necessary.
2-8 In-Line Filter
It is recommended that an in-line filter be installed upstream from the
device to prevent the possibility of any foreign material entering the flow
sensor or control valve. The filtering element should be replaced
periodically or ultrasonically cleaned.
2-9 Mechanical Installation
The recommended installation procedure guidelines are as follows:
The device should be located in a clean, dry atmosphere relatively
free from shock and vibration.
Leave sufficient room for access to the user interface and MAC
ID and baud rate switches (if equipped) at the top of the device.
Install the device in such a manner that permits easy purge and
removal if the device requires servicing.

The GF40 Series also utilizes MultiFlo
®
technology that allows the user to
configure standard configurations ("SAs") or "blanks" for a variety of pure
gases and mixtures. As a result, MultiFlo
®
technology enables the user to
reduce unique inventory requirements.
2-10 Flow Controller Installation Arrangement
Typical gas supply arrangements are shown in Figure 2-1. GF40s are often
arranged inside a gas panel. Configure standard configurations ("SAs") or
"blanks" for a variety of pure gases and mixtures. As a result, MultiFlo
technology enables the user to reduce unique inventory requirements.

2-11 Purge the Gas Supply Line Before GF40 Series Installation
Before operating the GF40 Series, the gas supply line must be completely
purged with nitrogen or argon to ensure the line is free from toxic or
flammable gases, contaminants, moisture, and oxygen. The purge gas
must be free of moisture and oxygen to less than 100 ppb. Purge the gas
lines as follows or in accordance with prescribed company and safety
procedures.
1. Shut off the process gas supply valve(s) upstream of the GF40 Series.
If such a valve is not available, shut the valve on the gas panel. Tag the
valve at this point to prevent accidental re-exposure of the process gas
to the gas line.
2. Cycle purge the gas line with dry nitrogen or argon to fully flush out the
process gas. Cycle purging consists of evacuating to a low pressure
adequate to induce out-gassing and then purging to remove adhered
moisture and oxygen. If a toxic or reactive gas is present and a clogged
GF40 Series is suspected, then proceed with caution. Pump down and
purge the GF40 Series from both downstream and upstream lines. If
check valves are present in the gas line, both pumping down and
purging are required. Pumping down without purging is inadequate. If a
good vacuum source is not available, the GF40 Series can be de-
contaminated by purge only.
3. Repeat the purge cycle several times within 2-4 hours to complete the
cleaning. For toxic and corrosive gasses, it is recommended to use
