The electric circuits in this turbine meter do not have ananti-explosion structure.
Do Not2.

Do not use this product for the measurement of corrosive gases or
the gases listed below.
It may corrode parts in use or cause a leakage of gas. In
addition, the measurements can be inaccurate.
Toxic gases

Do NotOthersChlorine, hydrogen cyanide, nitrogen dioxide, fluorine
Hydrogen chloride, boron trifluoride, boron dioxide
Sulfur dioxide, hydrogen fluoride, hydrogen sulfide
Ammonia, chlorine dioxide, oxygen, hydrogen,heliumDepending on the property of the gas to be measured, the meter
may become deteriorated in performance or damaged. Contact us
before measuring a special gas.

3.

Do not give an impact to the meter.
The meter is a precision measuring
instrument. Do not give a strong impact tothe meter or hit the meter with an object.
Besides, do not insert a cylindrical object
into the meter. It may cause a leakage ofgas or damage.

Do Not4.

Do not disassemble the meter.
The meter is a precision measuring
instrument. Do not disassemble it. It may
cause a leakage of gas.

Do not disassemble

5.

Conduct an airtightness test to the installed meter, including thepipes located prior and subsequent to it.
Conduct an airtightness test
between these points.

Check that no leakage occurs at apressure 1.1 times larger than the
maximum allowable working pressure.

Disposable after use

DoThis product contains a lithium battery, and therefore be sure not to dispose it
in the general disposal route.
Be sure not to put this product into fire. It may cause fire and/or explosion.
Since the flow meter is made by putting metals and resin parts together, it
must be discarded as industrial waste.

Do not install the meter at a place where oil mist or powder of dust is
wafting.
1. When this product is applied to LP gas using a vaporizer (petroleum gas), oil mistin the pipe (adhesive material caused by reliquefaction) may cause anabnormality in the rotating part and hinder accurate measurement.

CautionLP gasOil mist (Multiple carbide C5 or more)

2. The powder of dust (foreign particles) in the pipes may cause a failure in therotating part, hindering accurate measurement.

5.

Do not tighten the flange-stuffing nuts too strong when installing themeter.

Do Not6.

When connecting the meter to a counter pipe, align the centers.

Do

7.

Fasten all the nuts softly before tighten
them in an even, crisscross pattern.

Use caution not to cause an eccentricity,
inclination, or twist.
Do not apply an excessive stress loading
to the main body of the meter.

When using newly installed pipes, purge the pipes for removing foreign
objects before installing the meter.

Do

Remove weld tips
and foreign objects.

44Instructions for installation and piping work

1.

This turbine meter is designed with splash-proof and may be installed outdoors (under theeaves).

2.

This turbine meter can be used with both horizontal pipes and vertical pipes. Install it in the
middle of a straight pipe section.

3.

Do not install this turbine meter at a place where liquid such as oil or water may accumulate.

4.

Install a strainer (200 mesh) upstream from this turbine meter (see page 3).

5.

Do not install this turbine meter at a place where oil mist or powder of dust is wafting. It may
cause a failure in the rotating part, hindering accurate measurement (see page 4).

6.

Do not install this turbine meter to equipment that generates pulsatory motion, such as agas engine. The measurement will be inaccurate.

7.

Straight pipes having a length of 10D (i.e. 10 times the pipe diameter) or greater must be
provided prior and subsequent to this turbine meter.

8.

Use caution not to let foreign objects such as weld tips, foreign objects, and sealant enter
during the installation of pipes. (See P.4)

9.

Do not install this turbine meter at a place where it is subjected to an impact pressure.

10. Place noise sources, such as a control device of electromagnetic valves and output signallines, one to two meters away from the meter main body and the output signal line.
11. This product will set stand in three directions as shown in Fig. 1 of the protection covers
provided on the display in packing, so it can be easily set without adjustment when thedimensions from the floor level are fit. To protect the display, the protection covers should
not be removed until installation is completed.
12. The meter can be set in any direction against pipes.
The counter can be rotated by loosening the screws (M3 hexagon socket bolts with aconnector cap) at the lower part of the display about 4 mm (turn 8 times). The productshipped from the factory (Left inlet) can be changed to Right inlet, Top inlet, or Bottom inlet
by turning 180°to the right, 90°to the left, or 90°to the right, respectively. After turning thecounter 90°, fasten the screws to fix it. (See Fig.2)

5.

Open the inflow valve (upstream from the meter) gradually.
Open the outflow valve (downstream from the meter) gradually.
Check that the pilot is blinking.
Change the indicator display of the meter to an instantaneous flow rate value, and thenadjust the valve so that the flow rate value is in the specified range.
Change to pressure display to check predetermined pressure.
Use the meter in the normal mode with the integrated flow rate display.

Depending on the gas to be measured, installation environment, and use conditions, theperformance of the meter can rapidly deteriorate.
Periodically check the meter at the appropriate times in accordance with your usage
conditions.

When the pilot does not blink in spite of the presence of a gas flow, detach the meter fromthe pipes and then gently blow air into the inlet of the meter to check whether or not thepilot on the indicator blinks. If the pilot does not blink, check whether or not foreign objects
adhere to inside the meter. Remove such objects as necessary.
a.
Foreign objects on the rim of the impeller can be removed by giving a light impact
on the body.
b.
Due to the structural restrictions, it would not be possible to restore a meter that has
an adherent such as sealant that cannot be removed on-site. In such a case, youwill need to purchase a new one (i.e. the meter is not repairable).
If the foreign objects can be removed, blow air into the inlet again. When the pilot blinks,
the meter is now properly working.
When the most significant digit of the integrated flow rate display is blinking, it is warningthat the battery is running down. It is recommended that the meter should be replaced
immediately.

The operating flow rate range corresponds to the flow rate range in actual flow rate (uncorrected flowrate).
The pressure sensor consists of two types -- 3.5K (350kPa) and 9.9K (980kPa) --- and working
pressure is different according to each type. The maximum working pressure of actual flow rate model(without temperature and pressure correction) is 980 kPa.
Precision in use is 20 to 350 kPa for the 3.5 k type and 150 to 980 kPa for the 9.9 k type.
Not applicable to the actual flow rate model (without temperature and pressure correction).
Corrected trip flow rate in the case of corrected flow rate model (with temperature and pressure
correction), and uncorrected trip flow rate in the case of actual flow rate model (without temperatureand pressure correction).
Prevent oil mist (multiple carbide C5 or more), dust powder, etc. from entering into the meter.
In outdoor installation, avoid water from splashing on the meter.
