[1]Names and Functions of Each Parts
■
The flow rate of this product is measured by mass flow not
depended with temperature and pressure. Unit is L/min where
mass flow is converted to volumetric flow at 20 °C and 1
atmospheric pressure (101kPa).
■
The product can not be used as a business mater. Not conformed
to the Measurement Law, do not use the product for the
commercial purpose. Use the product as an industrial sensor.
■
Do not use the product with other than applicable working fluids,
or the accuracy can not be guaranteed. Do not use for corrosive
and flammable gases.
■
Install a filter, an air dryer and an oil mist filter (micro alescer) onto
the primary side (upstream) of the sensor since the compressed
air from the compressor contains drain (water, oil oxide and
foreign material, etc.)
■
When using this product with adsorption verification, etc., always
install an air filter onto the upstream of suction side to prevent
suction of foreign materials.
■
Do not use the product in an environment containing corrosive
gas such as salphur dioxide, etc.
■
Use the product within the ambient and fluid temperature ranges
0 to 50 °C. Even in the specified temperature range, do not use
the product where ambient and fluid temperatures will change
suddenly, and form dew condensations.
■
Use the product in accordance with specifications. If used out of
the maximum working pressure and working flow range, the
product may result in failures.
■
The protective structure of this product is equivalent to IP40. Do
not install the product where moisture, salt, dust or swarf is
contained, or where pressurized, or depressurized, neither.
When a dangerous situation may occur, or when there is high
urgency to a warning leading to fatal or serious injuries, if handling
is mistaken.
When a dangerous situation may occur if handling is mistaken,
leading to fatal or serious injuries.
When a dangerous situation may occur if handling is mistaken,
leading to minor injuries or physical damages.
Danger
!
■
A flammable fluid must not be used.
■
Do not use the product in flammable gas environment. Since
explosion-protection is not taken, explosion or fire may be
caused.
■
Arrange piping so that the flow direction agrees with the direction
of the arrow indicated on the sensor body.
■
When piping a sensor, do not apply excessive screw-in and load
torques to the port.
■
Flash the pipe to remove foreign substances and swarf, etc., in
inside of pipe before piping.
■
When piping, apply a spanner on the metal section not to apply
forces onto the resin section.
■
When piping, care must be taken that sealing tape and adhesive
must not enter into the inside.
■
When using the metal body with OUT side released, always
connect a joint, or the port filter may be removed.
■
If a push-in joint is used, the tube must be inserted certainly. Pulls
the tube to check that the tube not be come out.
■
Make sure that the joint and tube are not twisted or pulled, and
that moment load is not applied.
■
The display part uses the LCD. The display becomes difficult to
see for the view angle.
■
This product can be installed with any attitude; vertical, horizontal,
right or left.
■
This product cannot be used as a stop valve with zero leakage.
Slight leakage is allowed in product specifications.
■
Dust generation inside the paths of the needle valve is not zero.
Install a final clean filter in circuits where dust generation causes
problems.
■
When you install the panel, please install this product after piping
etc.
■
Check that lock nuts are not loose. Actuator speed cannot be
controlled if the lock nut is loose.
■
A stopper mechanism is provided, but damage could result if the
needle is turned too far.
■
Power supply voltage and outputs must be used with the
specified voltage. Applying the voltage more than specified
voltage may cause malfunction, damage of sensor, electric
shock or fire.
Do not apply load more than the rated output. Damage or fire of
the output may be caused.
■
For wiring, stop control unit/machinery and equipment, and turn
off the power supply.
■
This product and wiring must be installed as far away as possible
from noise source such as strong electric line, etc. Take other
countermeasures for a surge on the power supply line.
■
Do not short-circuit a load, or causing damage or burn.
■
Line color must be checked when wiring. Check the wiring color
with handling precaution, since improper wire connection may
result in damage, failure or malfunction of the sensor.
■
Use DC safety power supply thoroughly insulated from the AC
primary side for a power supply for the metal body (stainless
steel and aluminum bodies) type, while connecting or -
side on the power supply to F.G.
■
After the connectors are inserted, lay the connector covers over
the connectors.
■
Make sure that stress by forcible bend of pulling is not applies
directly to the sensor cable joint.
■
Output accuracy is affected by self exoergics caused by
energizing other than temperature characteristics. When using,
stand-by time (5 minutes and over after energizing) must be
provided.
■
For self-diagnosis, this product does not conduct flow rate
detecting switch operation for proximate 4 seconds immediately
after energized. Make a control circuit and programs to ignore
signals for approximate 2 seconds after energized.
■
This product cannot be used as a stop valve with zero leakage.
Slight leakage is allowed in product specifications.
■
Dust generation inside the paths of the needle valve is not zero.
Install a final clean filter in circuits where dust generation causes
problems.
■
When changing set-points of the output, stop the equip-ment,
then change the set-points, or an accident may occur.
■
Disassembly and modification must not be done or causing a
failure.
■
When an error occurs during operation, turn off power supply
immediately, and terminate the operation, and contact to the
sales office.
■
The material of case is resin. Solvent/alcohol/cleaner, etc., must
not be used to remove contamination, etc., or causing a resin to
be corroded. Wipe weakened neutral detergent with tightly
squeezed waste cloth, etc.
■
When out of flow rate range, analog output will be provided. [Hi]
or [Lo] will be displayed. However, accuracy is not guaranteed.
■
Do not push the display part., or causing damage.
■
Do not turn the knob too forcibly when fully closing or opening
the knob (within 0.05N-m). As well, do not pinch the lock nut
when adjusting the needle. Otherwise the needle will gall or be
broken.
