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.

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. Conrm these ratings before
commencing operation.
Bypass Loop
Strainer
Valve
Short Pipe
Flow Direction
NOTE: Making measure-
ment with Size 38 meter
is acceptable only in this
orientation (ow direction
from bottom to top).
Measures ow in either
direction (from top to
bottom or from top to
bottom).
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
・
m.
Avoid meter orientation
with nameplate top or
bottom.
Measures flow in either
direction (from left to right
or from right to left).

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.
