SAFETY PRECAUTION
Before using, read the following safety precaution to ensure correct handling of the flowmeter.
• The following items are important for safe operation and must be fully observed. These items are
classified into "DANGER" and "CAUTION".
Warning & Symbol Meaning
DANGER
CAUTION
• The items noted under "
• All the items are important and must be fully observed.
DANGER
CAUTION
Incorrect handling may lead to a risk of death or heavy injury.
Incorrect handling may lead to a risk of medium or light injury, or to a risk of
physical damage.
CAUTION
Caution on Installation and Piping
• This product has not an explosion-proof structure. Do not use it in a place
with explosive gases, otherwise, it can result in serious accidents such as
explosion, fire, etc.
• The unit should be installed in a place conforming with the installation
requirements noted in this instruction manual. Installation in an improper
location may lead to a risk of electric shocks, fire, malfunction, etc.
• The unit should be installed as noted in the manual. Improper installation
will cause falling, trouble or malfunction of the unit.
• During installation, make sure that the inside of the unit is free from cable
chips and other foreign objects to prevent fire, trouble, malfunction, etc.
• The items under "Caution on Installation" noted in the manual must be fully
observed. Careless installation may result in trouble or malfunction of the
unit.
" may also result in serious trouble depending on circumstances.

Caution on Wiring
• When performing wiring termination to prevent output trouble caused by
CAUTION
moisture, dew condensation or water leak, follow “Section 3.3. Flow
transmitter wiring” described in this manual
• Before performing the wiring work, be sure to turn OFF the main power to
prevent electric shocks.
• Do not perform wiring work outdoors in rainy days to prevent insulation
deterioration and dew condensation. Otherwise, it can result in trouble,
malfunction, etc.
• Be sure to connect a power source of correct rating. Connection of a
power source of incorrect rating may lead to a risk of fire.
• The unit must be earthed as specified to prevent electric shocks or
malfunction.
• The analog output signal cable should be wired as far away as possible
from high-voltage lines to prevent entry of noise signals as it will cause
malfunction of the unit.
• To prevent malfunction of the unit, the analog output signal cable and power
cable should be wired using separate conduits.
Caution on Maintenance/Inspection
• The unit should be inspected everyday to always obtain good results of
CAUTION
measurements.
• When measuring the insulation resistance between the power/output
terminal and the case, follow “Section 5.2.4. Measuring insulation
resistance” described in this manual.
• If the fuse is blown, detect and eliminate the cause, and then replace the
fuse with a spare. If there are no spares, replace the fuse with the one
specified in this manual (that must be prepared by customer). Use of a
fuse other than specified or its short-circuit may cause an electric shock or
fire. The fuse should be replaced according to “Section 5.3. Replacing
fuse” described in this manual.

1. PRODUCT OUTLINE
1.1. Outline
This high precision flowmeter is the world’s first clamp-on type ultrasonic flowmeter that adopts the pulse Doppler
method and the transit time method as its measurement principles. The ultrasonic flowmeter for industrial use
employs the pulse Doppler method, which directly measures flow distribution, thus easing straight pipe conditions and
allowing measurement of flows that have not grown into eddy or laminar flow. Combined use of the transit time
method allows the hybrid ultrasonic flowmeter to be used for measuring a significantly wide range of liquids. The
pulse Doppler method, which uses echoes coming from reflectors in a liquid to be measured, is ideal for the
measurement of liquids that contain air bubbles and particles. On the other hand, the transit time method, which
allows ultrasonic waves to pass through for measurement, is ideal for the measurement of clean liquids.
The new hybrid technique employing both the pulse Doppler and the transit time methods allows the flowmeter to be
used for wider range of applications. In addition, our self-developed switching algorithm ensures automatic switching
between the two methods depending on the conditions of a liquid to be measured (such as mixing status of air bubbles
or particles and flow rate), thus facilitating measurement.
1.1.1. Measurement principle
<Pulse Doppler method>
The pulse Doppler method measures flow distribution and flow rate based on the fact that Doppler frequency of the
•
echo coming from reflectors such as air bubbles and particles in liquids changes with fluctuation of flow rate.

<Transit time method>
Under the transit time method, ultrasonic pulses are propagated slanted from both upstream and downstream sides,

and time difference of flows are detected to measure the flow rate.

3.3. Flow transmitter wiring
3.3.1. Cautions in wiring
CAUTION
(1) Use a dedicated cable (FLY) as a signal cable between the detector (FSW) and the flow transmitter
(FSH). Do not join cable in the middle.
(2) Be sure to let the signal cables installed between the detector and the flow transmitter run through a
metal conduit tube. The signal cables for upper and the lower streams can be made to run through
the conduit tube together. However, do not let the power cable run through the conduit tube
together with the signal cables to avoid induction problems.
(3) Use shielded cables for output signals as far as possible.
(4) To prevent noise from coming in, avoid installing wiring in a duct together with the power cable.
(5) Directly ground the power cable that includes a ground lead.
(6) The flowmeter is not equipped with a power switch. Mount one separately.
(7) Tightly seal the unused wiring ports with supplied sealing caps.
3.3.2. Applicable wires
Use the following cables.
Power cable:
•
3-wire or 2-wire cabtyre cable
Nominal sectional area: 0.75 mm
Finished outer diameter: φ11 mm
Output signal cable:
•
2-wire or multi-wire cabtyre cable as required
Finished outer diameter: φ11 mm
Cable between detector and flow transmitter:
•
Cable for ultrasonic wave signals (High-frequency coaxial double shield cable with characteristic impedance
of 50 Ω, With waterproof BNC connector provided on one side)
Finished outer diameter: φ7.3 mm
Cable for temperature sensor (3-wire shielded cable, With waterproof connector provided on one side)
Finished outer diameter: φ6.9 mm
2
or more
3.3.3. Treatment of wiring port
The casing of the flow transmitter is of watertight type (IP67). However, to prevent entry of moisture and occurrence
of condensation, airtight processing of wiring ports is required. Be sure to take measures against entry of water using
the waterproof glands supplied with the instrument. Tightly seal unused glands using the supplied sealing caps.
CAUTION
Do not install the flow transmitter in a place subject to the occurrence of flooding.

constant appears as the DF value marked on the nameplate of the sensor unit. The setting need not be changed
normally. (Make the setting when the detector or the flow transmitter is replaced.)
