Carrying/storage case included
with purchase of unit.
Soft-side storage case is ideal for
storing your flowmeter in smaller
spaces such as your tool box.
Flowmeters that can measure flammable gases are becoming mandatory, due to the
increased use of hydrogen in chromatography. With its Ex rating, the Restek ProFLOW
6000 Flowmeter is designed specifically with explosive and flammable gases in mind.
The new Restek ProFLOW 6000 is the only flowmeter you need for any type of chro-
matography gas measurement because of its wide range of capabilities. The ProFLOW
6000 is an electronic device capable of measuring bidirectional volumetric flow for most
gases. Real-time measurements can be made for various types of flow paths, including
continually changing gas types. This portable unit is designed for easy hand-held use,
and the stand adds bench-top convenience.
State-of-the-art features include:
• Measures volumetric flow for all gases across a range of 0.5-500 mL/min.
• NIST traceable calibration
• Explosion-proof rating for flammable and explosive gases
• Accuracy of +/- 2% of flow or +/- 0.05 mL/min., whichever is greater
• Over range warning indicator
• Auto shut-off feature
• Use as a bench-top or hand-held unit
• Ergonomic design and side grips for comfort
• Measures most gas types*
• Convenient carrying/storage case included
• CE certified
• Uses 2-AA batteries
• Data output via USB port
• Re-calibration service available
Backed by a 1-year warranty, the Restek ProFLOW 6000 flowmeter will set the industry
standard for electronic flowmeters!

1.0 Introduction
Restek’s ProFLOW 6000 Flowmeter is specifically designed for use with gas chromatography (GC) systems. The probe is applied directly to the
gas flow stream and the measured flow rate is presented on the LCD screen. Units of flow are measured in mL/min.
This unit provides continuous real-time measurements of gas streams ranging from 0.50 mL/min to 500 mL/min. Because the technology uses
volumetric flow measurement, the unit is compatible with all laboratory gases.
CAUTION: Do NOT exceed maximum operating flow rates.
Recalibration may be required if the unit has been
subjected to extreme flow rates.
Always use appropriate laboratory safety practices when
operating this device. Wear laboratory safety goggles when
operating this unit.
NOTE: There are no serviceable parts in this unit. Opening the
device—other than to change the batteries—or tampering with the
internal parts will void the factory warranty.
NOTE: To ensure accurate measurements and effective clearance of
the flow gas from the unit, DO NOT obstruct the vent holes on the
back of the unit.

5.0 Operating instructions
CAUTION: Do not exceed maximum operating flow rates.
Recalibration may be required if the unit has been sub-
jected to extreme flow rates.
Connect the white probe end tip to the output of the gas flow line to
be measured. Be sure the probe tip connection is completely sealed
around the flow source outlet and is free of leaks (Figure 4).
Press and hold the (power) button until the unit responds
with a regular clicking sound. The ProFLOW will immediately begin
to provide flow measurements (Figure 5). Wait for the measured val-
ues to stabilize. It takes a few seconds for the unit to reach a steady
state with the gas flow line.
To power down the unit press and hold the (power) button
until the unit stops clicking.
The unit is equipped with a timed auto shutoff option (Default: 6
minutes).
➜ See Section 8.7: Adjust Auto Shutoff Duration (p.12).

6.0 Interpreting results
The unit has an operating range of 0.50mL/min. to 500mL/min. (Figure 7). If the flow is less than
0.50mL/min., the display will read “under range”.
If the flow exceeds 515mL/min., the display will read “over range”. Excessively high flow rates may dam-
age this unit.
NOTE: units of mL/min. are equivalent to ccm.
6.1 Flow range display
The unit automatically adjusts the resolution of the display depending on the flow range being measured.

7.0 Data collection on the PC
WARNING: ONLY connect USB cable to USB port
while unit is OFF.
The ProFLOW 6000 provides you with a data stream of real time
flow values via the USB port (Figure 1, p. 3). In order to use this fea-
ture, you must first install the appropriate FTDI Virtual Com Port
(VCP) Driver available at:
http://www.ftdichip.com/Drivers/VCP.htm
The VCP driver will cause the ProFLOW to appear as a standard
RS-232 port. This will work on any operating system for which
there is an FTDI VCP driver. After installing the driver, connecting
the device, and determining which port it creates, you can access the
data stream through any programmatical means, or by using any
serial terminal software.
For Windows systems:
To determine which port the ProFLOW is using, go to the Control
Panel and open System. Go to the Hardware tab and click the Device
Manager button. Expand the Ports (COM & LPT) entry. Make sure
the VCP driver is installed, then connect a powered ProFLOW 6000
to the USB port. You will see the new COM port appear. Open your
serial terminal.
➜ See Section 8.3: USB Activation (p.10).

If you do not already have serial terminal software, free, open source
options are available online (i.e. RealTerm, etc.). You can download
RealTerm* software from:
http://realterm.sourceforge.net/
After installation, click the Port tab and set the following:
Baud: 57600
Port: the appropriate VCP for your ProFLOW
Parity: None
Data Bits: 8 bits
Stop Bits: 1 bit
HardwareFlow Control: None
Go to the USB menu entry in the ProFLOW and turn the transmis-
sion on. Finally, click Open on the Port tab in RealTerm and you will
see the serial data stream begin in the terminal window (Figure 8).
If you would like to log the flow data, this can be done by clicking
on the Capture tab. Set File to the name and location of the log file
that you would like to save and click either the Start: Overwrite or
Start: Append buttons appropriately (Figure 9).

11.0 Volumetric vs. mass flow measurements
The Restek ProFLOW 6000 is a volumetric flow measurement device. Volumetric flow is the measure-
ment of the volume of gas through a conveyance per quantity of time. Standard units of measure for
this parameter are given in mL/min. The advantage of measuring volumetric flow is its independence to
the composition of the flow gas. It is not necessary to correct the flow values based on the gas composi-
tion, as is required for mass flow devices.
Mass flow measures the weight of the gas flowing through the instrument per quantity of time. Mass
flow units of measure are commonly g/sec.
12.0 Bubble flowmeter measurements
If you employ bubble flowmeters in your laboratory, you may find they give slightly different flow rate
values than the Restek ProFLOW 6000. This error is due to technology limitations inherent in the bub-
ble flowmeter device; error from variances in air humidity within the bubble chamber and its direct
contribution to the measured flow rate. In the event a bubble flowmeter is used to measure flow gas
where the gas is at elevated temperatures, the error due to humidity contributions can be extreme. For
the most accurate measurement of laboratory gas flow rates, we recommend using the Restek ProFLOW
6000 over bubble flowmeters.

13.0 Product case specifications 14.0 Calibration and service
The Restek ProFLOW 6000 comes factory calibrated and carries a
one year warranty from time of purchase. All units are calibrated to
NIST traceable standards.
Recommended schedule for recalibration is once every year from
time of purchase. Customers will need to return the unit to Restek
for recalibration. At that time, preventative maintenance services
can also be performed. A fee will be charged for recalibration and
servicing of the unit. Prolonged failure to recalibrate the instrument
may result in increased error.
Call Technical Service at 800-356-1688 or 814-353-1300, ext. 4 (or your Restek representative)
if you have any questions about this product or any other Restek product.
Please have the serial number available when calling Restek with any concerns you may have.
Additional charges may apply if the warranty is expired or the damage is due to misuse.
