Flow received state
FLOW
The FA Series flow meter measure flow rates using heat from the heater
and a temperature sensor. In a no flow state, the air temperature
distribution around the heater is uniform, so there is no difference in the
temperature between the upstream and downstream temperature sensor
positions. When flow is received in this state, the downstream temperature
rises while the upstream temperature falls, so a temperature difference
between the upstream and downstream sensor positions is generated.
This temperature different is measured and a flow rate is calculated.
■Rotary display
The display of the flow meter can be rotated 90°to the left or 180°to the right,
making it easy to read regardless of whether piping is horizontal or vertical.

■Features
●Separation measurement using an orifice for large-volume flow measurement at each piping port and small
pressure load.
●A self-diagnostic function simplifies troubleshooting in the case of product trouble.
●In the case of the FAS-030, FAS-060, and FAS-120 models, replacement required in the case of malfunction
can be achieve by replacing the bypass unit only, without detaching piping. However, the ±3%FS guaranteed
accuracy of the replacement product becomes ±5%FS.
●Range extension function
The FA Series flow meter displays up to double the maximum flow measurement range, and support analog
output and switch output.
However, the measurement accuracy of the additional part is approximately ±10%RD.
●Reverse flow detection function
FA Series flow meters can display a reverse flow (flow in the opposite direction from unit's flow arrow) up to 30% of the
maximum flow measurement range, and flow integration. However, reverse flow measurement accuracy is approximately
±6%FS, and analog output and switch output (except for some integrating functions) is not possible.
Example of use
Flow measurement
between lines and
divisions enables
division-specific cost
allocation. It also
helps to avoid over
use of air.
Knowing the flow over
time provides a means to
reduce power consumption
by optimization of
compressor operations
(load, unload, power off).
The integrated
reverse flow makes it
possible to integrate
reverse flows as well.
A wide flow measurement
range makes it possible to
obtain an understanding
of line stoppage time and
the amount of leakage.
* Remark: RD stands for "reading" (read value). With the FAS-002, error is ±30 ℓ/min (ANR) [±1.06 ft3/min] (normal)
for an instantaneous flow display of 300 ℓ/min (ANR) [10.6 ft3/min] (normal) and error is ±40 ℓ/min (ANR) [±1.413
ft3/min] (normal) for an instantaneous flow display of 400 ℓ/min (ANR) [14.1 ft3/min] (normal).
The results of air
consumption
reduction is readily
apparent from values
that are produced.

Safety Precautions (Flow Meters FA Series)
DANGER
●Do not attempt any adjustment (connecting or disconnecting
wire connectors, piping work, etc.) to mechanisms attached to
the product while the product is operating. Abnormal operation
creates the risk of personal injury.
WARNING
●Do not apply external magnetic field to the flow meter while it
is operating. Unintended operations could damage equipment
or cause injury.
●When wiring, take care to ensure that wiring polarity is correct.
Incorrect polarity could result in damage to the flow meter.
CAUTION
●Do not subject flow meter cables that have connectors to
excessive loads by pulling on them, lifting the product by
them, or by placing heavy objects on them. Doing so may
cause current leakage or defective continuity leading to fire,
electric shock, or abnormal operation.
●While handling the flow meter, do not subject them to
excessive shock (490 m/s2[50 G] or greater) by hitting,
dropping or bumping it. Even if the product appears
undamaged, damage to internal components can cause
abnormal operation.
●Avoid short circuiting loads.
Turning on switch output while a load short-circuit condition
exists can cause damage to the flow meter due to over
current.
Load short-circuit example: output lead of switch output
connected to DC power supply.
The safety precautions below are specific to FA Series flow
meters. For other safety precautions in addition to the infor-
mation below, also be sure to read the safety precautions at
the front of the general personal catalog.
Handling Instructions and Precautions
General precautions
Mounting location
Avoid installing the FA Series Flow Meter in the following types of locations.
1. Locations where the ambient temperature or product temperature is -10℃
[14℉] or lower, or exceeds 60℃[140℉].
2. Locations where the ambient humidity exceeds 90%RH.
3. Locations subjected to sudden temperature changes that can cause
condensation.
4. Locations subjected to concentrations of corrosive and/or flammable gasses.
5. Locations subjected to high amounts of dust, salt, iron powder, or other
conductive matter, moisture, oil mist, or organic solvents.
6. Locations where the product is directly subjected to vibration and/or impact.
7. Locations exposed to direct sunlight.
8. Locations where water, rain, or other moisture can get on the product.
9. Locations where oil or chemicals can get on the product.
10. Locations that are always wet or dusty, or subject to water or dust.
11. Locations where strong magnetism or strong electric fields are being
generated.
Operation outside the maximum flow range
When the flow rate exceeds the maximum flow rate range of the FA
Series Flow Meter, the alarm message " " will alternate on the
display with the flow rate reading. Always use this flow meter within the
specified maximum flow rate range.
Mounting and piping
Piping
1. The FA Series Flow Meter is a precision instrument. Take care when handling
it. It can be damaged by dropping it or otherwise subjecting it to strong impact.
2. Whenever connecting piping to the FA Series Flow Meter, make sure that the
direction of the arrow marked on it matches the flow direction of the fluid.
3. When connecting piping, do not apply force to the bypass unit section.
4. When connecting piping, secure the main flow channel and rotate the pipe to
the suitable tightening torque range.

5. Take care to keep foreign matter from flowing into the FA Series Flow Meter.
Any rust, water droplets, oil mist, dust, or other foreign matter inside piping
that gets into the FA Series Flow Meter creates the risk of measurement
error and damage to the flow meter. Before installation, be sure to thoroughly
flush both the upstream and downstream piping (pipe cleaning) and check to
make sure there is no foreign matter present.

Handling Instructions and Precautions
Mounting direction 1: With horizontal piping, display upwards. (Standard direction)
Mounting direction 2: Horizontal piping with the display on the right when viewed from the
flow meter IN side pipe. When using this installation attitude, set the
low flow cut parameter value to 5. Failure to do so will cause the flow
rate to be displayed (output) even when there is no fluid flowing. The
normal flow side and back flow side integral functions activate, causing
the flow rate values to be integrated.

6. When connecting piping, apply an appropriate amount of sealant. Do not apply
sealant to the first two threads of the end of the pipe. Over-application of sealant can
cause it to get inside the piping, creating the risk of measurement error and damage
to the FA Series Flow Meter.
7. If different-diameter piping, a regulator, filter, valve, or other piping equipment is
installed upstream from the FA Series Flow Meter, be sure to provide a straight pipe
section as recommended. See "Specification accuracy and straight pipe section" for
more information. Failure to provide a straight pipe section can cause flow rate errors.
8. Connecting expansion pipe or a tube coupler without providing a straight pipe
section can produce a negative flow rate reading due to back flow in bypass unit,
even though there is normal flow as far as the product is concerned.
9. Installing the display section on horizontal piping so it is in a downward orientation
may cause rust, water droplets, oil mist, dust, or other foreign matter to adhere to
the sensor, creating the risk of measurement errors and damage to the FA Series
Flow Meter. Do not use the display section in a downward orientation.
Installing the display section on horizontal piping in a sideways orientation will cause
errors due to the effect of the attitude. For details, see "Installation Attitudes" below.
10. Do not install in locations where the effects of pulsating flow or flow maldistribution
are present, such as in the vicinity of the compressor delivery port, on bellows
piping, etc. Also, do not install in a location where a regulator or check valve is
performing hunting. Doing so creates the risk of measurement error.

Note 4: Contact Koganei for information about 1 1/2B and 2B size filters and mist filters.
5: Required direct piping when connecting a filter with the same diameter as the flow meter.
6: A reduction pipe connection example (within the product specification range (±3%FS)) for
the FAS-002 is shown below.
When connecting one size larger piping (for example, 1/2B for the FAS-002), take the
specified value*+5D for direct piping before the flow meter and the specified value*+5D for the
direct piping after the flow meter.
* Piping length when connecting piping one size larger than the specified value.
7: A reduction pipe connection example (within the product specification range (±3%FS)) for
the FAS-005is shown below.
Do not connect piping that is thinner than the connection port without direct piping. Reverse
flow by the bypass unit is possible even though the product is providing normal direction
flow, and produce a negative reading on the flow display. Or an extremely low flow value
may be displayed in place of the actual flow.
Or when connecting one size smaller piping (for example, 1/4B for the FAS-005), take the
specified value*+10D for direct piping before the flow meter and the specified value*+5D for
the direct piping after the flow meter.
* Piping length when connecting piping one size smaller than the specified value.
8: Reference diagrams for a single elbow and double elbow are shown below.
9: Install valves for flow adjustment downstream from the flow meter.
10:Install when the distance from the flow meter is greater than the specified distance. It makes
no difference whether piping from the regulator to the flow meter is constructed of tubing or
an elbow bend. However, install the required direct piping when connecting with the flow
meter with an elbow bend. Allow for distance even if a filter or mist filter is inserted.

Filter
• Whenever there is the risk of foreign matter (dust, sediment, oil mist, etc.) being
mixed in with the measured fluid, be sure to install upstream from the FA Series Flow
Meter a filter and mist filter that can remove foreign matter measuring 1μm or larger.
• Periodically inspect and replace filters, and perform other periodic maintenance as
required.
Specification accuracy and pipe section
Install the FA Series Flow Meter so the arrow marked on its label is pointed in the
same direction as the fluid flow direction. When connecting different diameter tubing,
valves, filters, and other equipment, provides straight pipe in accordance with the
information in the table below.
A "straight pipe" is straight piping that is the same bore diameter as the flow meter.
The following types of pipes are suitable as straight pipe: carbon steel pipes for
ordinary piping (JIS G3452), carbon steel pipes for pressure service (JIS G3454),
Schedule 40 or less, and stainless steel pipes (JIS G3459), Schedule 40.
Note1
For equipment not included in the table below, provide 15D or larger straight piping
when installing it upstream from the FA Series Flow Meter, and 5D or larger straight
piping when installing it downstream from the FA Series Flow Meter. The letter D
represents the bore diameter.
Note2
When measuring back flow in addition to normal flow, the same length as the
upstream straight pipe is required downstream from the FA Series Flow Meter.
Note 1: Note that accuracy deteriorates when piping carbon steel pipes for pressure
service (JIS G3454) or stainless steel pipes (JIS G3459), larger than Schedule 40
is connected. A larger schedule results in a smaller pipe inside diameter which
causes a pipe effect and deteriorated accuracy.
2: The approximate D (bore diameter) for FAS-002 (1/4B) is 8 mm [0.315 in], for
FAS-005 (1/2B) is 15 mm [0.591 in], for FAS-030 (1B) is 25 mm [0.984 in], for
FAS-060 (1 1/2B) is 40 mm [1.575 in], and for FAS-120 (2B) is 50 mm [1.969 in].
3: Always provide a filter upstream from the mist filter.

•For connection with a quick fitting
Provide the straight pipe section noted in the table below when
connecting the FA Series Flow Meter to a quick fitting.
Connecting without a straight pipe section can produce a
negative reading due to bypass unit back flow, even if flow in the
main channel itself is normal direction flow. Also, the readout may
show an extremely low flow rate instead of the actual flow rate.

Connections
1. Use a power supply that is within the specification range.
2. Wire a cable with connector separately from power lines and high voltage
lines (use a separate conduit). Noise from these lines may cause the
equipment to operate erratically.
3. When connecting a cable with connector, align the core wire and push it in as
far as it will go. Next, tighten the connector nut by hand. When tightening the
nut, be sure to keep it within the prescribed torque (0.4 to 0.6 N·m [3.540 to
5.311 in·lbf] range). Failure to do so creates the risk of damage to the FA
Series Flow Meter and inability to maintain the IP65 protective structure, and
loosening of the nut due to vibration.
4. Do not pull on the cable with strong force and do not lift the FA Series Flow Meter
by the cable (pull out strength: 40 N [8.992 lbf] or less; bend strength; 20 N [4.496
lbf] or less). Also, do not subject the cable to repeated bending or pulling force.
5. Do not rotate the center part of the connector (see figure below) while the
connector is inserted fully into the FA Series Flow Meter. Doing so will cause
the FA Series Flow Meter connector to rotate, which can cause internal wiring
to twist and become damaged.

6. Always turn off the power supply before doing any wiring.
7. Keep load resistance connected to the instantaneous flow rate output below 300 Ω.
8. Keep cable and connector ends away from moisture when doing wiring.
9. Double-check to make sure that wiring is correct before turning on power.
Wiring error creates the risk of damage and erratic operation.

Note 1: (normal) is a value converted to a 0°C [32°F], 101.325 kPa [29.9 inHg] (abs) flow.
2: "FS flow" is the maximum flow of the flow measurement range.
3: "RD" stands for "reading" (read value).
4: A minus (−) flow rate value indicates a back flow rate (flow in the direction opposite that indicated by the flow meter arrow).
5: Regardless of the unit of display and the decimal point position, this indicates resolution from the lowest display digit.
6: A flow rate inside of parentheses ( ) is for installation attitudes 2 and 3.
7: This accuracy is a value representing instantaneous flow rate display accuracy along with instantaneous display repeatability.
8: See the installation attitudes on page 1675.
9: Replacing the bypass unit with a new unit causes instantaneous flow rate display accuracy to become ±5％FS ±1 digit. (FAS-030, FAS-060, FAS-120)
10: The back flow side cannot output.
11: Back flow side settings cannot be configured.

Setting Guidelines
Nomenclature and functions
① Flow rate display : 5-digit, 7-segment LED that normally shows the
instantaneous flow rate and integrated flow rate.
For integrated flow rate, the displayed value is
divided between the four highest digits and five
lowest digits. In setting mode, the display shows
setting items and values. When an alarm occurs, it
shows an alarm code.
②LED lamps :
L/min Lights during instantaneous flow rate display.
L/min Lights during integrated flow rate display.
EV Remains lit while switch output is on.
AL Lights when an alarm occurs.
Key switches :
⑥
Used to switch the display screen, enter setting
mode, etc.
⑤ ④
Used to configure function settings and parameter
settings, to switch between the instantaneous flow rate
peak value, lower value, and information display, and to
reset the integrated value.
③ Used to check configuring function and parameter
setting contents, and to go to the information display.
Main flow path
: Connects to piping. There is an IN side and an
OUT side.
Bypass unit :
FAS-030, FAS-060, and FAS-120 support
replacement with new bypass unit.
Display:
The display on top of the bypass unit can be rotated so
it is parallel with the flow path. From the basic position
shown in the illustration above, the display can be tilted
180right or 90left, a range of 270
.
Connector: Used for power input and signal connection.
Mounting bolts : Secures the bypass unit to the main channel.
Integration functions
The function setting can be configured for integrated count up or
integrated count down.
•
When the integrated count up reaches 999999999, it reverts to 0 and
continues from there.
• Integrated count down continues from the specified starting value until
it reaches 0. Count down stops when the integrated value becomes 0.
• The integrated count up values are recorded in non-volatile memory
every 10 counts. This means that, depending on when power is cut,
the exact current integrated count up value may not be stored in
memory.
Also, note that the integrated count down value is not recorded.
• To reset the integrated value to 0, check to make sure that the count
screen upper order digits or lower digits are displayed, and then hold
down both the key and key for at least five seconds.
In the case of a integrated countdown, the above operation resets the
integrated value to the integration event set value. An integrated value
reset records the current integrated value to non-volatile memory.
●Integrated process and operations during back flow
The integrated process when back flow occurs is performed in
accordance with the selected integrated option as shown in the
table below.
Note: In either case, the back flow integrated volume can be viewed on the
information display.

The integration counter stops counting up during back flow and the
back flow is stocked to the back flow counter. After that, if the flow
becomes normal, the portion stocked on the back flow counter is
consumed and then the integration counter starts count up again.
The stock of the back
flow counter reaches 0,
so the integration

Flow rate display unit
The display unit for instantaneous flow rate and integrated flow
rate can be changed as required.
Flow rate display example
Display unit setting C02 : 00 C02 : 01 C02 : 02 C02 : 03
Unit
ℓ/min (ANR) [ft3/min (SCFM)], R m3/h, m3[ft3] m3/min, m3[ft3] kg/h, kg [lb]
Instantaneous flow rate 200 [7.1] 12.0 [423.72] 0.200 [7.062] 15.5 [34.172]
Integrated flow rate 100000000 [3532000] 100000.000 [3531000] 100000.000 [3531000] 100000.000 [220462]
Conversion from R/min to each unit are shown below.
ｍ3/h=R/min×60÷1000
kg/h=R/min×60÷1000×1. 293
Density at 0℃[32℉], 101.325 kPa [29.9 inHg] (abs) is
assumed to be 1. 293.
Note: After changing the unit of flow rate display, select the applicable sticker
from among those provided and affix it to the flow meter.
Analog output
The instantaneous flow rate is output as an analog current (4 to
20 mA). Parameter settings can be used to change the flow rate
value (display value) at 20 mA output. Setting resolution can be
set in display value 1-digit intervals. Initial default settings are 4
mA at flow rate 0, and 20 mA at 100% FS flow rate.
Operating pressure selection
Selecting a value that is in the vicinity of operating pressure will
perform output compensation of the selected pressure and
reduce the effects of pressure characteristics.
Reference temperature selection
The flow rate display reference temperature can be set in 1℃
[34℉] steps within the range of 0 to 35℃[32 to 95℉].
(Factory default temperature is 0℃. )
Low flow cut
Low flow cut can be set in 1% steps within the range of 1 to 50%
of FS flow rate (factory default: 1%).
At a setting of 1%, for example, 0 is always displayed as the flow
rate when the FS flow rate is within the range of −1 to 1%.
The low flow cut setting is applied to instantaneous flow rate and
integrated display values, and to the analog output value.
Self-diagnostic function
The self-diagnostic function automatically causes the FA Series
Flow Meter to display an alarm whenever there is an abnormality
in the output signal of the sensor that measures the flow rate or
a memory abnormality.
Back flow measurement
Enables measurement of back flow up to −30% of the FS flow rate.
Note: For information about accuracy, see the specifications on
page 1678 and 1679.
Flow rate range expansion function
Enables measurement up to 200% of the FS flow rate.
Note: For information about accuracy, see the specifications on
page 1678 and 1679.

Maintenance and troubleshooting
Maintenance
To ensure proper operation, conduct periodic inspection at least
once a year.
If the self-diagnostic function displays an alarm that does not
clear even though the cause of the alarm is eliminated, request
servicing from Koganei. Contact the Overseas Department for
more information.
The addresses and telephone numbers are shown at the back of
this manual.
Troubleshooting
●Abnormalities and remedies
Symptom Remedy
Nothing appears
on the display.
・Make sure the supply power voltage and polarity are
being applied correctly.
・Make sure that connectors are connected correctly.
The flow rate
display does not
become zero even
when valves
upstream or
downstream from
the flow meter is
closed and there is
no flow. (Output
signal is not 4 mA. )
・Make sure there are no air leaks in the piping.
・Make sure that wiring is correct.
・When the flow meter is installed on horizontal piping
with the display sideways, influence of the installa-
tion attitude may cause zero point drift. (Since instal-
lation on horizontal piping with the display sideways
causes the accuracy guarantee flow rate range to
become 5 to 100% FS, set the low flow cut in this
case to 5%. )
・In a location subject to large ambient temperature
fluctuation and large flow fluid temperature fluctua-
tion, convection within the piping may be detected
as flow. Perform measurement after temperature has
stabilized sufficiently.

standard instru-
ment. The instru-
ment is outside the
accuracy range.
・Make sure there are no air leaks in the piping.
・Check for foreign matter trapped in the main channel
orifice. If foreign matter is present, remove it.
・Check for dirt, oil, or other foreign matter in piping
and the flow meter connection port. If foreign matter
is present, Koganei servicing and replacement are
required. Contact your nearest Koganei sales office
or the Overseas Department.
・Check to make sure that wiring is correct.
・Check to make sure that there is no large fluctuation
in flow rate within a few seconds and that the
measurement range is not exceeded by a large
amount.
●Alarm displays and required actions
Alarm
Code Item Description Cause Remedy
Flow rate
over
A flow rate that
exceeds the
value set by the
maximum
display value
parameter
setting is
flowing. Or a
back flow that
exceeds the
back flow rate
range is flowing.
There may
be a high flow
rate outside
of the
maximum
display range
or back flow.
Note 1
Check if a high flow rate
exists and eliminate its
cause. If the instantaneous
flow rate display when the
alarm occurs shows a
minus (–) sign, back flow
occurs. Eliminate the cause
of the back flow. The alarm
will cease displaying when
the actual flow rate
becomes within the display
range flow rate.

tion cannot
be per-
formed.
The regis-
tered channel
ID numbers
may be
wrong.
Use maintenance mode
to register the correct
channel ID numbers. Note
2If changing the setting
does not clear the
alarm, turn the
instrument off and then
back on again. If this
does not clear the
alarm, request servicing.
Registra-

abnormality
2
Correct calculation
cannot be
performed because
of abnormal data
registered for the
flow sensor
characteristic
values.
Registered
characteristic
data may be
corrupted,
resulting in
abnormal
values.
Turn the instrument
off and then back on
again. If this does not
clear the alarm,
request servicing.
Sensor
abnormality
1
Flow rate
signal is
outside the
proper range.
The signal level
may be exceedingly
low due to a short
circuit caused by
adherence of
foreign matter or
excessive back flow
that exceeds the
measurement
range.
If excessive back flow is
the cause, this error will
clear automatically when
the flow rate returns
within the measurement
range. If it is not due to
excessive back flow and
the alarm does not clear
after a number of hours,
request servicing.
Sensor
abnormality
2
Flow rate
signal level
may not
match the
actual flow
rate.
Sensor may be
malfunctioning or
output may be
dropping.
Foreign matter
may be adhering
to sensor, or
there may be
condensation on
the sensor, etc.
Pass dry air through
the system. If the
error does not clear
after a number of
hours, request servic-
ing.
