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
ofce.
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.
FLOW MATE (OVAL M-Ⅲ) is adjusted and inspected completely with all the components of the meter-
(2)
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:
Keep FLOW MATE (OVAL M-Ⅲ) in store in the same container used for shipment from OVAL if possible.
(1)
Place of storage should conform to the following requirements:
(2)
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

spin too fast during the ushing or cleansing process.
CAUTION
(4)
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.

2. OPERATING CONDITIONS
To maintain the stated high accuracy and long service life of FLOW MATE (OVAL M-Ⅲ), make sure
that the flowrate, pressure, temperature and viscosity are held within the ratings. The operating
conditions appear in the GENERAL SPECIFICATIONS on page 15. Conrm these ratings before
commencing operation.
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

4. WIRING
NOTE : Also see the topic "WIRING" in the instruction
manual of the receiving instrument used.
4.1 Field Wiring
(1)Cables for eld wiring
The following cables should be used unless otherwise specied.
Shielded chloroprene cabtyre cables (kind 2, JIS C 3327, shielded) or shielded vinyl cabtyre
2
cables (JIS C 3312, shielded) with a conductor area 1.25mm
3-conductor cables may be used to suit your specic application. Shielded end should be grounded
t the ground terminal of the receiving instrument.
a
(2)Transmission length
With transmission cables conforming to JIS C 3327 or C 3312 conductor area 1.25mm
maximum transmission length is typically one kilometer.
If
NOTE:
it exceeds one kilometer, consult factory.
(3)Prevention of inductive interference
T
o minimize the possibility of stray current pickup, route the eld wiring sufciently 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.

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
a
dvances 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
u
pstream 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.
newly installed tubing assembly in particular requires daily net inspection for condition to prevent
A
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.
