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.
NOTE: Modifying the length of tubing can cause a shift in calibration.

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). (White
tubing ID 0.125"; OD 0.250")
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
values 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.)
 è See Section 8.6: Adjust Auto Shutoff Duration

6.0 Interpreting results
The unit has an operating range of 0.50 mL/min to 500 mL/min (Figure 7). If the flow is less than
0.50 mL/min., the display will read “under range.”
If the flow exceeds 515 mL/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.
Table III shows the resolution of the flow ranges.

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
feature, 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 programmatic 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, and then connect a powered ProFLOW
6000 to the USB port. You will see the new COM port appear. Open
your serial terminal.
è See Section 8.2: USB Activation
Figure 8: Screen capture of data collection.

- 8 -
www.restek.com
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: 115200
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
transmission 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).
*This software is not supplied or supported by Restek. User assumes all responsibility for the
downloading and use of the program.

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 that they give slightly different flow
rate values than the Restek ProFLOW 6000. This error is due to technology limitations inherent in
the bubble 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.

1.0 Einleitung
Restek’s ProFLOW 6000 Flow Meter wurde speziell für die Benutzung in Gaschromatographie (GC) Systemen entwickelt. Die Prüfspitze wird
direct an den Gasfluss gehalten und die gemessene Flussrate wird auf einem LCD Bildschirm angezeigt. Der Fluss wird in mL/min gemessen.
Dieses Gerät bietet kontinuierliche real-time Messungen von Gasströmen im Bereich von 0.50 mL/min bis 500 mL/min. Da die verwendete
Technologie auf volumetrischen Flussmessungen beruht ist das Gerät mit allen Laborgasen kompatible.
