1.BEFORE YOU BEGIN
Every meter is thoroughly tested before it leaves the factory. When received, it should be thoroughly
inspected for any indication of damage during transit.
Necessary handling precautions are described in this section; read the instructions carefully. As for
other information, refer to the respective section. For any inquiries, contact your nearest OVAL sales
ofce.
CAUTION
When you make inquiries, include the product name, model code, serial number, ratings
and other pertinent information.
1.1 Transit Consideration
(1) To safeguard against damage during transit, transport FLOW MATE (OVAL M-
Ⅲ) to the installation
site in the original cardboard container used for shipment from the factory if circumstances
permit.
(2) FLOW MATE (OVAL M-Ⅲ)is adjusted and inspected completely with all the components of the meter-
sensor unit, pulse generator, etc. For this reason, treat them as one complete assembly.
1.2 Storage Considerations
If the meter is going to be stored for long periods of time upon receipt before installation, it could be
damaged or deteriorated due to unforeseen circumstances. If a lengthy storage is expected, the
following precautions should be taken:
(1) Keep FLOW MATE (OVAL M-Ⅲ) in store in the same container used for shipment from OVAL if possible.
(2) Place of storage should conform to the following requirements:
★Free from rainwater.
★Free from vibration and impact shocks.
★Temperature and relative humidity in the storage place are at or near room temperature and
humidity (around 25℃ and 65% RH).
(3) If FLOW MATE (OVAL M-Ⅲ) that has once been placed in service is to be stored, it should be purged
with clean air, N2 gas, etc. to remove residual process uid from the meter interior, ttings, tubing
inner walls, housing exterior and other components.
NOTE: Use clean detergent, etc. to remove contaminants if necessary. Do not allow the meter to
spin too fast during the ushing or cleansing process.
(4) CAUTION
The Super Micro 38 has a plastic resin molded joint ; therefore, excessive tightening
or repetition of mounting and dismounting more than necessary may result in broken
joint or loss of airtightness due to deformed taper screw.
(5) If you want to store the meter for extended periods of time, keep it stored under the conditions
similar to those during shipment.
1.3 Structural Consideration
FLOW MATE (OVAL M-Ⅲ) is intended for indoor use. Do not expose it to rainwater or running water.

CAUTION
If the body material of FLOW MATE (OVAL M -Ⅲ) is aluminum + anodized aluminum coating,
it is not serviceable for water and corrosive liquids.
3. INSTALLATION
3.1 Tubing Considerations
(1)The tubing assembly must be thoroughly flushed. Flushing must be performed before meter
installation. Couple a short pipe section in place of the meter (see the ushing set-up given below).
(2)The meter should be installed exercising due care to avoid pipe strains.
(3)When screwing in the ttings, be very careful not to allow metal chips and seal tape protrusions to
get into the meter.
(4)The meter should be located downstream of the pump.
(5)Flow direction must conform to the arrow mark indicated on the meter body.
(6)The strainer should be located upstream of, and as close to the meter as possible.
(7)The physical orientation of the meter should be such that its nameplate is vertical as shown below.
(8)When installing Size 38 meter in the tubing assembly, screwing torque at the tting should be
held with in 10N

4. WIRING
4.1 Field Wiring
(1)Cables for eld wiring
The following cables should be used unless otherwise specied.
Shielded chloroprene cabtyre cables (kind 2, JIS C 3327, shielded) or shielded vinyl cabtyre
cables (JIS C 3312, shielded) with a conductor area 1.25mm2.
3-conductor cables may be used to suit your specic application. Shielded end should be grounded
at the ground terminal of the receiving instrument.
(2)Transmission length
With transmission cables conforming to JIS C 3327 or C 3312 conductor area 1.25mm2, the
maximum transmission length is typically one kilometer.
NOTE: If it exceeds one kilometer, consult factory.
(3)Prevention of inductive interference
To minimize the possibility of stray current pickup, route the eld wiring sufciently away from other
power cables and power circuits.
CAUTION: Verify the validity of flowmeter (pulse generator) to receiving instrument
combination by their product No., instrument No., etc. before making wiring
connections.
NOTE : Also see the topic "WIRING" in the instruction
manual of the receiving instrument used.

5. OPERATING INSTRUCTIONS
5.1 Operation
Adhere to the operations sequence outlined below for the first time operation, allowing the
process fluid flow within the flow range specified.
NOTE: See the tubing diagram below.
(1) Shut off upstream valve (A) on the inlet side and valve (B) on the outlet side and then open bypass
line valve (C) to allow the uid in the bypass line, thereby removing weld spatters, metal chips, scales
and other foreign matter left in the tubing assembly.
CAUTION: This is particularly important for new or rebuilt tubing assemblies.
(2) Carefully and slightly at rst, open valve (A) upstream of the meter progressively and then, slightly
at rst, open valve (B) downstream of the meter progressively.
(3) Slowly close bypass line valve (C) and make sure that the total counter in the receiving instrument
advances in response. Bubbles in the measuring chamber can produce meter errors; bleeding all
air is essential at the time of meter installation in the tubing assembly.
With Meter Size 38, allowing the uid at 50ml/min. or so for more than one minute is suggested.
With meters other than Size 38, allow the uid at a rate 10 to 20% of the maximum owrate for
more than 15 minutes and ensure that all the air has escaped from the tubing assembly.
In applications where temperature exceeds 60℃, run the meter at least for 30 minutes in this state
to ensure that heat distribution in the measuring chamber becomes uniform.
(4) Following the break-in (preheating) period, shut off bypass line valve (C) completely and open
upstream valve (A) progressively until fully open and slowly open downstream valve (B) until the
rated ow is reached.
(5) Flowrate should be regulated with downstream valve (B) and should be held within the rating.
(6) The strainer net should be inspected for condition and cleaned on a regular basis.
A newly installed tubing assembly in particular requires daily net inspection for condition to prevent
any ow obstructions. The service intervals may be reduced progressively to, say once a week
thereafter.
CAUTION: Use extra care to avoid running the meter too fast.

5.2 Operating Precautions
(1) When changing owrates:
In applications where the owrate varies or
where shutoff valve opening and closure takes
place in batch operation, avoid rapid changes
in owrate across the meter.
Operating the meter at owrates in excess of
the maximum allowable owrate will nullify the
guaranteed accuracy, reduce the meter life and
may result in faulty conditions, such as burn
of bearings or rotor-to-measuring chamber
contact.
(2) Where the temperature of metered uid
changes:
Avoid rapid temperature changes in the meter.
Temperature changes of the uid in the meter
should be held with in 3℃ perminute.
Extra care should be used particularly when
making a ow measurement in batch operation
without the provision of heat tracing of the
tubing where the fuid temperature differs from
atmospheric temperature.
If rapid temperature changes are anticipated,
heat trace the tubing assembly as well as
the meter.
(3) Liquids of low steam pressure:
Liquids with low viscosity and low steam
pressure can easily vaporize and their
temperature and pressure should therefore
be strictly controlled.
During operation, the temperature of bearings
in the meter usually runs higher than that of
the metered uid. Vapors around the bearings
can present problems, such as unusual noise
and bearing seizure.
(4) Highly corrosive liquids:
When you make a measurement of highly
corrosive liquids, appropriate materials should
be used for tanks and tubing assembly.
Heterogeneous materials originally contained
in the metered fluid, or certain substances
that have leaked out of the tanks and/or
tubing of inappropriate materials, may lead to
costly downtime, as a result of locked rotors,
for example, when they are allowed into the
measuring chamber.

S-176-9-E
CAUTION
5.3 Safety Precautions Before Operation Shutdown
(1) Valves should be closed progressively.
Rapid valve closure could, under certain tubing conditions, cause a sharp pressure rise by water
hammer, or hydraulic shock, which can result in damage to the meter.
(2) Precautions against pressure buildup on closure
Complete closure of valves upstream and downstream of the meter creates a totally enclosed
space between them and a rapid buildup resulting from a rise in atmospheric temperature can be
a potential source of damage to the meter.
(3) Liquids ready to adhere or gel
With liquids that tend to adhere, solidify or gel when allowed to reside, ush away the metered
liquids thoroughly with appropriate detergent from the interior of meter before shutting down
meter operation. Negligence of this precaution and leaving the meter as it is, you may possibly
have problems when you want to start the meter the next time.

6. DISASSEMBLY AND INSPECTION
◎While recommended servicing intervals vary according to the given operating conditions, the
general rule to follow is to perform periodic disassembly and inspection once a year.
◎Refer to the exploded views on pages 12 to 14.
6.1 Meter Body Disassembly and Inspection
Complaint - Fluid will not run.
The most likely cause is that scales become jammed in the oval rotors, making them immovable
and blocking the uid ow.
CAUTION: Be sure to turn off power before you start servicing.
① Take off all four pan head with cross point
screwdriver.
② With pan head screws taken off, the front cover
and pulse generator are now separable from
the meter body. Be careful not to drop the meter
body.
Pan Head Screws
Nameplate
Front
Cover
③ With the front cover removed, the measuring
chamber and oval rotors are accessible.
④ Remove the oval rotors from the measuring
chamber and inspect individual component
parts for condition.
NOTE:The rotor shafts should be drawn out
axially.
(a) Are oval rotors jammed by foreign solids?
(b) Are rotors, shafts and other components
worn?
(c) Are the inner walls of measuring chamber
and front cover damaged?
(d) Are signal generating magnets rusted?
Upon completion of these inspections, wash
clean the oval rotors, rotor shafts, measuring
chamber and front cover thoroughly with fresh
water or cleaning oil.
CAUTION
1. Deep scoring, high spots caused by impressions, or other irregularities, should be
reconditioned to be smooth and flat with oilstone.
2. FLOW MATE (OVAL M-Ⅲ) is a precision instrument. Disassembly and inspection should
be conducted indoors as a general rule. If it is desired to make disassembly and
inspection without removing the meter from the tubing assembly, reduce internal pressure
in the tubing assembly completely to zero, shut off valves upstream and downstream of
the meter completely, drain the tubing assembly and then place a suitable liquid receptacle
immediately below the meter. Use extra care to keep out dirt, sand or other contaminants from
disassembled component parts.

First Rotor
6.2 Meter Body Assembly
Precautions Before Assembly:
Wash clean oval rotors, inner walls of rotor shaft bearings, measuring chamber and inlet/
outlet ports thoroughly to remove dirt, sand and other contaminants completely.
(1) Rotor installation
Installation is correct with the signal generating
magnet embedded side facing the front cover.
The rst rotor (match mark “ ●”) installs on the
upper shaft when the flow direction is from
right to left.
The second rotor (match mark “ ●●”) installs
on the lower shaft. Install the rotors carefully
with match marks as shown in the inset.
NOTES
1. (※): Match marks are stamped only on product
code “LSF□□C□−□□”(metal rotors).
2. Match marks do not appear on rotors of material
K (special resin) or P (PPS resin, PEEK resin).
Verify proper gear engagement at step (2) below.

(2) Conrming the rotor engagement
Hand rotate the rotors at least one complete revolution to see that they are correctly engaged.
(3) Front cover installation
Firstly, install the O-ring in place. If the O-ring is damaged or swollen by the metered uid, it may
not seat properly in the front cover groove. If this is the case, replace it with a new one.
Install four pan head screws and tighten them uniformly until the front cover is rmly secured to
the meter body.
(4) Checking smooth rotation
Check smooth rotation of the rotors and proper output pulse counting with the connected
receiving instrument by allowing air or water into the meter.
CAUTION
Rotation check should be conducted within a range of slow rotor rotation.
Allowing the rotors to spin too fast will lead to burn or other damage to the components.

7. TROUBLESHOOTING
PROBLEM POSSIBLE CAUSE HANDLING
1. Counter will not count
1. Flowrate low. 1. Open valves progressively.
2. Pump pressure or head
pressure low.
2. Taking pressure loss of the
entire tubing system into
account, select a proper pump
pressure or head pressure.
3. Power source voltage is out
of specication.
3. Supply 12 to 24 VDC power to the
pulse generator.
4. Oval rotors are jammed by
foreign matter, interrupting the
ow.
4. Disassemble the meter body
by referring to the meter body
disassembly and inspection
procedure in Section 6. Wash
clean the rotors and related
components.
5. The oval rotors are installed
the wrong way.
5. Install the rotors correctly,
referring to the meter body
assembly and inspection
procedure in Sec. 6.2.
2. Liquid leaks.
1. Incomplete seal of the tubing. 1. Tighten up the tube connections
or replace gaskets.
2. Incomplete front cover seal
of the meter body.
2. Check front cover tting bolts
