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

Incorrect handling may lead to a risk of death or heavy injury.

CAUTION

Incorrect handling may lead to a risk of medium or light injury, or to a risk of

physical damage.

•The items noted under "

CAUTION

" may also result in serious trouble depending on circumstances.

( All the items are important and must be fully observed.

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.

observed. Careless installation may result in trouble or malfunction of the unit.

SAFETY PRECAUTION

INF-TN1FSH-E - iii -

Caution on Wiring

CAUTION

•When performing wiring termination to prevent output trouble caused by

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

CAUTION

•The unit should be inspected everyday to always obtain good results of

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

•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.

•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.
