re.
During the absence of airflow, the temperature
distribution around the heater is symmetrical.
When there is airflow, the temperature of the
upwind side cools down and the temperature
of the downwind side warms up, disrupting the
symmetry of the temperature distribution.
Q1 There are two balloons; each having different volumes.
But these balloons have the same mass. Why is that?
The volume increases/decreases according to the pressure and
temperature changes. The mass, on the other hand,
remains constant regardless of the environmental changes.
The mass ow measurement allows measurement performance
that is not affected by the changes in the environment.
A
Q2 Why is mass ow measurement required?
AAn accurate measurement of the ow is required especially for
combustion control. Omron’s ow sensor enables measuring the
gas ow based on the mass ow measurement.
Realizing a highly accurate ow measurement,

Sensitivity
The product size is reduced by using the
world-smallest class size MEMS sensor element
Compact
The sensor can be placed anywhere
thanks to its dust-resistant structure.
Omron’s unique design of 3D flow path
provides a high level of reliability by
separating dust particles to reduce its
effect on the sensor chip. Additionally,
Omron succeeded in reducing the
sensor size, allowing it to be used in
wider range of applications.
By detecting this temperature difference appearing as a
difference in the electromotive forces developed by the
thermopiles, it allows the mass flow rate and mass flow
velocity to be measured without the influence of
temperature and pressure. Since the thermopile generates
the thermo-electromotive force, the power consumption is
much lower than when using the resistivity method.

D6F-D MEMS 2-Axis Flow Sensor
Safety Precautions
The sensor is a precision device, and if large shock and load is
applied, it may cause a failure or characteristic change. Please
do not use the sensor which is added excessive shock to the ter-
minals, discompose the cover, or has fallen.
● Applicable medium and Device mounting
• Depending on the mounting position and the ambient environ-
ment, the foreign object such as dust can adhere to the inside
of the device and can cause clogging of the part of flow path.
As a result, the device may not perform as intended. And, the
characteristic specified in this document may not be main-
tained. Please use the device after enough ex-ante evaluation
under the condition of actual use in order to confirm the perfor-
mance and safety in the application.
• For the gasses other than the applicable medium, please use
the device in your responsibility after the confirmation of its
performance and safety.
However, do not use in the presence of inflammable gases,
such as hydrogen, methane, ethane, and a liquefied petro-
leum gas. In addition, do not use with corrosive gases (such
as chlorine, sulfur, acid, alkali, ammonia etc.)
• The direction of the arrow on top of the body shows the posi-
tive direction of the device output in each axis. Please install
the device in a correct direction corresponding to the direction
of the flow. With the wrong installation, the device cannot mea-
sure flow direction correctly.
• After installation, the device may not perform as intended by
the presence of a flow obstacle around the device.
• After Installation, the device operation and its performance
should be checked before actual use in the application.
• Horizontal device orientation (top cover side up) is recom-
mended. If the device orientation is not horizontal, the output
may shift as an offset more than +/3%F.S.. For more details of
offset compensation features, please refer to the communica-
tion specification.
• The device may not operate properly, if a foreign object or a
flow obstacle is placed around the entrance of the flow path.
● Use environment
Please do not use the device in the following environments:
• Places where the device directly receives radiant heat from an
apparatus.
• Places where the device is exposed to water, salt water, water
droplets and oil splash.
• Places where the device is exposed to direct sunlight.
• Places with volatile gas, inflammable gas or corrosive gas
(such as chlorine, sulfur, acid, alkali, ammonia etc.)
• Places where frequent temperature changes.
• Places where dusty condition.
• Places with the possibility of freezing and dew condensation.
• Places where the device receives large magnitudes of vibra-
tion and shock.
• Places where the device receives strong electric field effect or
magnetic field effect.
● Noise Countermeasures
• Please check electrical noise condition before actual use. The
device may not perform as intended by the effect from electri-
cal noise.
• The voltage input that exceeds absolute maximum ratings
must not be applied. This can damage the electrical circuit of
the device. Place the protection circuit as needed, so that the
voltage to the lines will not exceed absolute maximum ratings.
• Take particular care to install away from AC power transform-
ers, live mains power lines and high power magnetic circuits.
• The device may not operate properly where the place with the
equipment that generates strong high-frequency wave or
surge.
• Please attach surge absorber or noise filter to the peripheral
equipment that generates noise.
• In order to prevent inductive noise, wiring of the device must
be separated from the power line with the high voltage and
large current.
• When using with a switching regulator or DC-DC convertor,
switching noise may affect the device operation.
● Handling
• Please handle with countermeasure against static electricity.
• Do not make a direct solder connection to the integral termi-
nals; this may result in damage, and possibly cause failure. It
is recommended to use the standard straight CAT5e LAN
cable and to ensure correct connection.
• Do not mix up the wiring. This can damage the device and
cause the failure.
• Power must be supplied from the single source. And, do not
apply different voltage to the device from each connector. This
may damage the device and also the host equipment (master).
• After wiring cables, please do not apply excessive pulling force
to the connector. Tensile force of 12N or more can cause the
failure.
• Changing DIP switch setting must be done when in power off
state.
● Communication
• When using the multiple devices on the same bus, please
make sure that there is no device that has the same slave
address, please refer to the communication specification
(No.MDPE-12-0146).
• When using built-in termination resistor, please enable it only
to one device at the end of the bus.
• Please make sure that there are no multiple devices with ter-
mination resistors enabled.
• Please make sure that baud rate setting must be same for the
host equipment (master) on the same bus.

Common Precautions for the D6F Series
Safety Precautions
● Sensor Applications
The D6F is built for use with general-purpose devices. In particu-
lar, when using the D6F for applications with the safety require-
ments described below, take steps to ensure system and device
safety through measures such as fail-safe designs, redundant
designs, and regular inspections.
•Safety devices for ensuring safety for persons
•Transportation equipment control (such as applications to
stop operation)
•Aviation and space equipment
•Nuclear power equipment
Do not use the D6F for applications in which D6F operation
would directly affect human life.
● Fluids, Pipe Mounting and Sensor Installation
All D6F Models
(1)
Use clean fluids. Install a filter or mist separator on the
inflow pipe. Failure to do so may result in malfunction or
changes in characteristics due to dust or mist. This does not
apply to the D6F-W, D6F-V, D6F-P and D6F-PH.
(2)
Do not use corrosive gases other than the specified applica-
ble fluids (such as chlorine, sulfur, acid,or alkali) . Doing so
may cause product failure.
(3)
The specified performance may not be obtained if the D6F is
used for fluids other than the specified applicable fluids.
(4)
After removing the Sensor from the package, do not allow
foreign particles to enter the piping. Foreign particles in the
piping may cause product failure.
(5)
Install the Sensor so that the fluid flows in the direction indi-
cated by the arrow on the Sensor. Correct measurements
cannot be obtained if the fluid flows in the wrong direction.
This does not apply to the D6F-V, D6F-P and D6F-PH.
(6)
It is recommended that the Sensor (except for the D6F-A3)
be mounted horizontally. If it is not mounted horizontally, an
error of ±1% FS or higher may result.
(7)
Install the Sensor on a flat surface. Incorrect installation may
damage the Sensor and make it impossible to obtain correct
measurements.
(8)
Make sure that the power to all equipment is turned OFF
before you install the Sensor. Installing the Sensor while the
power supply is ON may result in electrical shock or abnor-
mal operation.
(9)
Always check operation after installation.
(10)
Do not drop the Sensor or disassemble the cover.
D6F-A1
(1)
Make sure that pipes with bamboo joints are airtight. Correct
measurements cannot be obtained if there is leakage from
joints.
(2)
Use M3 panhead screws to install the Sensor, and tighten
them to a maximum torque of 0.59 N•m.
D6F-N2/-L2
(1)
Use the Rc 1/4 tapped threads for the pipes, and tighten the
threads to a maximum torque of 5 N•m. Tightening beyond
this value may result in fractures, which can cause leaks.
Apply a suitable amount of pipe sealer. Do not apply sealer
on the first two threads from the end of the threaded section.
When you tighten the pipes, do not allow foreign matter or
oil on the joint area.
(2)
Use M3 panhead screws to install the Sensor, and tighten
them to a maximum torque of 0.59 N•m.
D6F-A3
(1)
When installing the pipes, use M5 screws for the joints and
tighten to a torque of 1.5 N•m maximum. Use sealing tape to
make the joints airtight. Incorrect installation may make it
impossible to obtain correct measurements.
(2)
It is recommended that the Sensor be mounted either hori-
zontally or vertically. Mounting the Sensor at an angle may
make it impossible to obtain correct measurements.
(3)
Use M3 panhead screws to install the Sensor, and tighten
them to a maximum torque of 0.59 N•m.
D6F-A5
(1)
Use M3 panhead screws to install the Sensor, and tighten
them to a maximum torque of 0.59 N•m.
(2)
Install O-rings to seal the fluid inlet and outlet points. The
recommended O-ring is JIS B 2401, nominal number P5.
D6F-A6
(1)
Use the appropriate threads (R1/4, NPT1/8 or NPT1/2) for
the pipes, and tighten the pipes to a maximum torque of 5
N•m. Tightening beyond this value may result in fractures,
which can cause leaks. When you tighten the pipes, do not
allow foreign matter or oil on the joint area. Use a spanner or
adjustable wrench to turn the connecting section (aluminum
alloy) and connect the pipe. Do not place the spanner or
wrench on the Sensor (PPS). Doing so may damage the
Sensor or result in leaks. Apply a suitable amount of pipe
sealer. Do not apply sealer on the first two threads from the
end of the threaded section. When you tighten the pipes, do
not allow foreign matter or oil on the joint area.
(2)
Use M3 panhead screws to install the Sensor, and tighten
them to a maximum torque of 0.59 N•m.

(1)
Use male quick couplings for the piping, and secure them
with the applicable quick fasteners.
(2)
Do not apply excessive force to the adapter section when
connecting the pipes. If strong force is applied to the con-
nected pipes, or if strong force is applied directly to the
adapter section while holding the Sensor, it may damage
the Sensor or cause leakage.
Note. There is a possibility that leak damage or faulty of the body occurs when
static load of more than 40 N is applied to 300 mm from the center of
product as fulcrum point.
D6F-P0001A1/-P0010A1/-P0010A2
(1)
Depending on the ambient environment and installation
location, dust, dirt, and other foreign matter may come in
inside the Sensor and block a part or all of the flow path or
accumulate on internal components. This may result in the
Sensor not being able to perform to the specifications given
above. Always perform a pre-evaluation on your actual
equipment and be aware of the possible problems that may
occur before you use the Sensor with the actual equipment.

D6F-V
(1)
Depending on the ambient environment and installation
location, dust, dirt, and other foreign matter may come in
inside the Sensor and block a part or all of the flow path or
accumulate on internal components. This may result in the
Sensor not being able to perform to the specifications given
above. Always perform a pre-evaluation on your actual
equipment and be aware of the possible problems that may
occur before you use the Sensor with the actual equipment.
(2)
Use M3 panhead screws to install the Sensor, and tighten
them to a maximum torque of 0.59 N•m.
(3)
This Sensor does not contain any protective circuits. Never
allow the electrical load to exceed the maximum ratings.
Doing so may damage the circuits. Install protective circuits
if required.
(4)
Mount the Sensor so that the flow inlet side (the side with
the logo) is perpendicular to the windward side and ensure
that the flow inlet and flow outlet are not blocked in any way.
If the Sensor is not mounted correctly, accurate measure-
ments cannot be made.
● Operating Environment
Do not use the Sensor in the following locations:
•Locations directly subject to heat radiated from heating
equipment
•Locations subject to water or oil
•Locations subject to direct sunlight
•Locations subject to intense temperature changes
•Locations subject to icing or condensation
•Locations subject to excessive vibration or shock
● Countermeasures against Noise
Noise may make it impossible to obtain correct measurements.
Consider the following countermeasures.
•Allow as much space as possible between the Sensor and
devices that generates high frequencies (such as high-
frequency welders and high-frequency sewing machines)
or surges.
•Attach surge absorbers or noise filters to noise-generating
devices that are near the Sensor (in particular, equipment
with inductance, such as motors, transformers, solenoids,
and magnetic coils).
(It also helps to separate pipes and ducts, and to use
shielded cables.)
● Power Supply
•Force of connector terminal is 20 N max. Do not add
strength more than tension of wire bending to connector
at wiring. Install the connector coaxially to the fitting axis
with holding all wires. And pulling angle should be within
15 degrees.
•Use the applicable connectors. Directly soldering the con-
nection terminals will cause product failure. (except for the
D6F-PH)
•Check the terminal names and polarity and wire the power
supply correctly. Incorrect wiring will cause failure of inter-
nal components.
•When using a commercially available switching regulator, ground
the FG (frame ground) and G (ground) terminals.
● Handling
The sensor is a precision device, and if large shock and load is
applied, it may cause a failure or characteristic change. Please
do not use the sensor which is added excessive shock to the ter-
minals, discompose the cover, or has fallen.
•The sensor shall only be handled in electrostatic dis-
charge protected areas (EPA) under protected and con-
trolled conditions
The RoHS mark is displayed on the packing of products for
which the six substances banned by the RoHS Directive have
been abolished (both in processing and in the electronic compo-
nents mounted to the PCBs).
* RoHS marking may be terminated if it is later determined that parts that were
previously treated as RoHS compliant are not compliant due to circumstanc-
es at the supplier of the parts.
● RoHS Compliance Criteria
The following standards are used to determine RoHS compli-
ance for the six banned substances.
(Items to which the RoHS Directive is not applicable are not
given.)
•Lead: 1,000 ppm max.
•Hexavalent chromium: 1,000 ppm max.
•Mercury: 1,000 ppm max.
•PBB: 1,000 ppm max.
