Applications
The sensor of FLUEREX consists of a rectier that converts the
compressed air to a uniform ow and a platinum thin lm resistor that
detects the ow rate. The rectier works to make the ow uniform
when a bent pipe such as an elbow is installed immediately before the
sensor. Through the use of multiple rectication plates, the pressure
loss is suppressed and an adequate rectication effect is realized.
When the compressed air does not ow, the platinum thin lm
sensor that detects the ow rate is heated from the uid temperature
to a certain constant temperature. When the compressed air ows,
the amount of heat proportional to the weight of air is detracted and
the current that intends to maintain the constant temperature ows
in the circuit inside the platinum thin lm sensor that detects the ow
rate. By receiving this current as a ow rate signal, the display
section displays a practical atmospheric pressure, instantaneous
ow rate or integrating ow of the air converted to 0°C.
In addition, by the platinum thin film sensor that detects the
fluid temperature, the temperature of the compressed air is
measured and the temperature correction is performed.
Functions

Flow sensor for compressed air (FLUEREX)
Medium ow rate
PF500F to PF4000F Series
● Flow rate range: 25 to 500, 50 to 1000,
100 to 2000, 200 to 4000 L/min(normal)
*1 : If the compressed air contains foreign substances, water or oil, the ow rate cannot be detected and this causes "sensor error".
Install a lter, refrigeration air dryer, and oil mist lter on the upstream side of the ow rate sensor.
*2 :
When the ow rate is below the min. ow rate range, the display becomes 0. The display value out of the ow rate range is outside the guaranteed precision.
*3 : Note that the switch output is not available if option "A1" (4 to 20 mADC) or "A6" (integrated pulse) is selected.
*4: Refer to descriptions of integrated pulse output on page 1383 for details of pulse output.
*5 : Note that the integrating ow value is reset when the power supply is turned OFF.

Flow sensor for compressed air (FLUEREX)
modular connection
PFU500F to PFU2000F Series
● Flow rate range: 25 to 500, 50 to 1000, 100 to 2000 L /min (normal)
*1 : If the compressed air contains foreign substances, water or oil, the ow rate cannot be detected and this causes "sensor error".
Install a lter, refrigeration air dryer, and oil mist lter on the upstream side of the ow rate sensor.
*2 :
When the ow rate is below the min. ow rate range, the display becomes 0. The display value out of the ow rate range is outside the guaranteed precision.
*3 : Note that the switch output is not available if option "A1" (4 to 20 mADC) or "A6" (integrated pulse) is selected.
*4: Refer to descriptions of integrated pulse output on page 1383 for details of pulse output.
*5 : Note that the integrating ow value is reset when the power supply is turned OFF.

· Three types of setting are available according to the application.
● Switch output parameters
●0 < L < H
● 0 < (L-h) ≤ L < (H-h)
Note)
1) Switch output ON indicates that the transistor is energized.
2) For safety, set the output only when the upper level equipment is in
stop state.
3) The settings of parameters 0 and 1 should satisfy the following
conditions. Otherwise operation cannot be guaranteed.
Note that the output is always OFF if L=H=h=0 (factory default).
1) In the write mode described on the right, clear
with key operation.
2) Clear by turning the power OFF.

Functions and operations for monitor
Measurement mode
Note) Integrating ow is displayed in integers.
In 10 seconds, the light goes from blinking to
steady and the display automatically returns to
the instantaneous ow rate display.
Holding down for 2 seconds conrms the setting: the blinking light will
change to a steady light and the display will constantly show an
integrated value. As the measurement setting is retained even if the
power is turned OFF, resetting is not necessary.
To return to the instantaneous ow rate display, hold down for 2 seconds again.

Pneumatic components (sensors)
Safety Precautions
Be sure to read this section before use.
Refer to Intro Page 63 for general precautions regarding pneumatic components
and refer to " Safety precautions" for detailed precautions for individual series.
Design/selection
1. Checking the specications
■Never use with a ammable uid.
■Use the product in the range of conditions specied
for the product.
The product in this catalog is designed for use only in a compressed
air system. Use with pressures or temperatures outside the
specications range may result in damage or operation failure.
■This product cannot be used as a billing meter.
Do not use this product for commercial transactions
as it is not compliant with the Measurement Act.
Intended applications include industrial sensors.
■Because compressed air or nitrogen gas is used as
an applicable uid, do not use uids other than
these, because accuracy cannot be guaranteed.
2. Safety design
■
Take measures to prevent physical harm or property
damage in the event of failure of this product .
■Understand the characteristics of compressed air
before designing a pneumatic circuit.
●Pop-out, air discharge, or leakage due to air compression
and expansion may occur.
●Design the circuit so that compressed air in the system is
exhausted.
■Check for leakage current to avoid malfunction
caused by the leakage current.
●When using a programmable controller, leakage current
may cause malfunction.
■Although there is no movable section in the ow
rate sensor, when repeating ON/OFF of the
solenoid valve, the mesh section or xed section of
the rectier may move slightly and this may result
in the generation of particles. When the generation
of particles must be eliminated, be sure to install a
lter on the secondary side (downstream side) of
the ow rate sensor.
■Exerts no inuence on performance as it uses
compressed air and a small amount of leakage is
tolerable. Contact CKD if no leakage is required.
■
The monitor of the display separated PFD Series
cannot be connected to PF-F/PFU Series. When
making the connection, this product could break.
■Precautions for analog output "A1"
Connecting multiple analog output 4 to 20 mA sensors
to the same common input circuit (host computer, PLC,
etc.) as shown above causes interference between the
signals, preventing correct operation. In this case, use
the voltage output (standard, A2, A3).
* The voltage at point A and that at point B are
connected inside the input circuit, which gives
them the same electrical potential, creating an
error in the respective analog outputs.
If the power supply (24 VDC) of the host input circuit is not isolated,
install separate power supplies for the input circuit and the sensor.
3. Design by application
■Never use this product in an explosive gas
atmosphere. The structure is not explosion-proof,
and explosions or res could occur.
■When using nitrogen gas as an applicable uid,
oxygen deciency could be caused. Observe the
following instructions.
(1) Use in well ventilated locations.
(2) Ventilate the work area when nitrogen gas is being used.
(3) Inspect nitrogen gas piping regularly to avoid leaks.

DANGER
WARNING
CAUTION
1. Installation
■Use power supply voltage and output within the
specied voltage.
If voltage exceeding the specied voltage is applied, the
sensor could malfunction or be damaged, or electrical shock
or re could occur. Do not use any load that exceeds the
rated output. Otherwise, output damage or re may result.
■
Check the line color and terminal number when connecting
wires. Incorrect wiring could result in sensor damage and
malfunctions, so check wire color and terminal number
against the instruction manual before wiring.
Install a noise lter if required.
■
Ensure that wires are properly insulated.
Check that wires do not come into contact with other
circuits, that no ground faults occur, and that the
insulator between terminals is not defective. Otherwise,
overcurrent may ow into the sensor, causing damage.
■
Keep the product away from high voltage cables, high
voltage equipment and power equipment such as motors.
■Check that there are no cutting chips and wire dust
on the connector of the sensor before wiring.
CAUTION
2. Pre-operation conrmation
■
After connecting piping, always check all pipe connections
for air leaks before supplying compressed air.
●
Apply a leakage detection agent to pipe connections with a
brush and check for air leaks. Make sure that the leak
detection agent does not adhere to the resin parts. Otherwise
resin parts could be damaged, which is dangerous.
■
Keep the cable away from all noise sources, including
power distribution wires. Noise can cause malfunctions.
■Do not short-circuit the output transistor.
When a load is short-circuited, overcurrent protection circuit is
triggered to prevent damage to the output transistor; however, if
this state persists, the output transistor could be damaged.
Overcurrent protection...Approx.70 mA
■
Do not remove the pneumatic component packaging and the
piping port dust-proof cap until just before starting piping.
●Removing the piping port cap before piping work may
cause foreign matter to enter the pneumatic components
from the piping port, resulting in failure or malfunction.
■
When mounting pneumatic components, do not use a
mounting method that relies on support from the piping.
