ADM Flow Meter
Principles of Operation
10 Agilent CrossLab CS ADM Flow Meter Operation Manual
Principles of Operation
The ADM flow meter provides continuous, real-time
measurements of dry gas flows, such as those used for gas
chromatography. Unlike bubble flow meters, the flow meter
operates without liquids, bubbles, or glass parts. When
activated, a solenoid actuated valve interrupts the gas flow
momentarily. The gas flow moves a diaphragm in proportion to
the flow rate. This movement is transformed by the flow
meter's electronics into a digital value, which is displayed on the
flow meter's screen. The flow meter provides two different
types of flow measurements: volumetric flow (mL/min) and
mass flow reported in standard cubic centimeters per minute
(sccm). Mass flow values are calculated from the volumetric
measurements by correcting for ambient temperature and
atmospheric pressure, and reporting the flow rate referenced to
0 °C and one atmosphere of pressure, using digital temperature
and pressure sensors installed in the mainframe of the
flow meter.
The flow meter uses a replaceable cartridge that contains all
parts subject to calibration. This eliminates the need to ship the
entire meter back to the factory to maintain its calibration. The
cartridge calibration is valid for a period of one year from its first
use. A new, calibrated cartridge can be ordered in advance, and
installed when necessary.
When the flow meter is powered on with a new cartridge
installed, the current date is written to the cartridge’s memory
based on the mainframe’s internal clock. Each time the flow
meter is turned on, the meter will compare the current date to
the initial turn on date of the cartridge. If the initial turn on date
is more than a year from the current date, the flow meter will
flash a notification to the user that the calibration has expired.
The flow meter will still function with an expired calibration. This
eliminates downtime, enabling you to keep working. See
Installing and Replacing the Cartridge on page 31.
The flow meter is powered by three AA alkaline batteries. Power
can also be supplied via the micro USB port located on the side
of the unit.

Display
The flow meter has a bright OLED display with a battery
strength indicator.
The unit automatically adjusts the resolution of the display in
response to various gas flow ranges as follows:
When the battery strength indicator shows that the battery
strength is low, replace the batteries. See Replacing the
Batteries on page 33.

Operating Modes
Agilent CrossLab CS ADM Flow Meter Operation Manual 13
Operating Modes
With the flow meter switched on, briefly press the Power/Mode
button to scroll through the different operational modes.
The available modes are as follows:
Volumetric flow mode
This is the default mode on power up. In this mode, the
volumetric flow rate is displayed in mL/min.
Mass flow mode
In this mode, the volumetric flow rate is corrected taking into
account the current atmospheric pressure and ambient
temperature. The flow rate is displayed in sccm (standard cubic
centimeters per minute) referenced to one atmosphere of
pressure and 0 °C.

ADM Flow Meter
Split mode
14 Agilent CrossLab CS ADM Flow Meter Operation Manual
Split mode
In this mode, you can store a flow measurement as a reference
value, and then compare subsequent flow measurement values
as a ratio of the current measurement to the reference
measurement. This is useful when trouble shooting a GC Inlet.
Info mode
Info mode provides details on the flow meter and the installed
cartridge. In addition, Info mode allows you to set the display
brightness and control the Auto off functionality.
To access Info mode:
1With the unit switched on, repeatedly press the
Power/Mode button until Info mode is displayed.
2Once in Info mode, pressing the Enter/Clear/Toggle button
scrolls through the available screens.
Display brightness
Display brightness can be set to high or low.
To change the display brightness setting:
1With Info mode displayed, briefly press and release the
Enter/Clear/Toggle button to cycle through available
screens until the Brightness screen is displayed.
2Press and hold the Enter/Clear/Toggle button for
two seconds to toggle between High and Low options. The
screen brightness changes based on the selected option.

Auto off
In battery power mode, the unit defaults to “auto off” when the
power is on. This means that every time the unit is activated, a
“power-off” cycle begins, lasting for 10 minutes. The flow meter
will operate continuously until it is manually turned off.
In USB power mode, the Auto off function is always off and the
option to change the Auto off setting is disabled.
To change the Auto off setting:
1With Info mode displayed, briefly press and release the
Enter/Clear/Toggle button to cycle through available
screens until the Auto off screen is displayed.
2Press and hold the Enter/Clear/Toggle button for
two seconds to toggle between On and Off options. The
Auto off function changes based on the selected option.

Making a Flow Measurement
CAUTION
Make sure that the flow to be measured is within the range of
the flow meter (750 mL/min). Over ranging the flow meter can
damage the transducer.
NOTE
Always turn the flow meter on before connecting it to a
flow source.
1When the unit is powered on, it defaults to volumetric flow
mode. (If you want to use the mass flow mode, briefly
press the Power/Mode button.)
2Connect the flexible tubing to the gas source to
be measured.
3Wait for the reading to stabilize (1 to 2 seconds), then
observe the reading.
NOTE
Low flows (less than 1 mL/min) may take up to 5 seconds for
the reading to stabilize
