WARNING

This UL400 converter belongs to “permanent connected”

indstrument. The power line shoud be connected to a

“Switch” (or “Circuit Breaker”) to be able to turn off the

UL400 in any situation. Please confirm the following

items when installing the switch:

1. Please consider the safety issue in factory to decide

the location of the swtich.

2. The switch should be easy for operation.

3. An indication is necessary for notifying which switch

connected to UL400 conveter.

4. Confirm that the power is turn off before opening the

UL400 cover.

1. OUTLINE

The UL400 is a clamp-on type ultrasonic flow meter capable of measuring a flow rate in the metal or plastic piping with

a nominal diameter of 25~400 mm (UL430) or 25~1000 mm (UL450). An ultrasonic sensor is installed on the existing

piping from the exterior by the clamp-on system, and the flow rate can be easily measured without contacting the

measuring fluid because of no moving part or pressure loss. Pay special attention in installing the ultrasonic sensor

because the measuring accuracy and stability very depend on the installation of the sensor.

3. GENEAL PRECAUTIONS NOTES

3.1 Power supply

Pay attention to the following for the power supply to connect.

1) Voltage

Use the power source in the range of 100 to 240V for AC type converter (working voltage range: AC85~264V).

Use the power source 24DC for DC type converter (working voltage range: DC20~30V).

2) Frequency

Make it 50/60Hz for AC power source.

3) Common use with other power supply

Be sure to use the power supply for instrumentation, and avoid the common use with the power source for

power.

4) Noise

When sources of a noise such as an inverter are located near, be sure remove a noise at the generation source

OTES

side using a noise filter.

5) Instantaneous power failure

Since it is an electric device, be careful not to cause instantaneous power failure.

3.2 Measurable fluid

Although any liquids can be measured, there is the following restriction.

1) Flow velocity

The minimum full scale which can be set up is 0.3 m/s in flow velocity conversion, but it cannot be correctly

measured in the line in very slow velocity. Calculate the flow velocity in a full scale by the following formula,

and confirm that the flow velocity is 0.3m/s or more.

Measurement accuracy is deteriorated at flow velocity of 1 m/s or less.

: Flow velocity (m/s)

: Flow rate (m3 /h)

: Inside dia. of pipe (mm)

2) Reynolds number

When the Reynolds number "Re" calculated by the above formula is 10000 or less, the measurement becomes

less accurate. Especially in case of the fluid of the high viscosity and the piping in small diameter,

keep it in mind that Reynolds number becomes smaller.

ρ:

Density (g/cm3 )

: Flow rate (m3 /h)

: Viscosity (mPa･s)

: Inside dia. of pipe (mm)

3) Acoustic velocity

The acoustic velocity of the fluid which can be setup is 1000 to 2500m/s.

4) Solids and bubbles

The UL400 has higher bubble resistance and slurry resistance than the conventional clamp-on type ultrasonic

flow meters, but is not suitable for large quantity of them.

5) Kinematic viscosity (mm2/s)

Kinematic viscosity can be setup is 0.3~40 mm2/s.

6) Fluid temperature

OTES

Max 90℃(the temperature of the surface on the pipe).

3.3 Notes on measuring piping

1) Measurable piping

Pipes which can be measured are as follows：

・ Nominal diameter：25 ~ 400mm (UL430)，25~1000mm(UL450)

・ Material： Metals

Plastic (PP, PVC, PVDF etc.)

2) Installation position of ultrasonic sensor

・ Avoid a welding line portion to install the ultrasonic sensor.

・ For piping of an old iron, the ultrasonic wave may not be transmitted correctly due to the rust or corrosion

etc., and the measurement may not be correctly made. In this case, the position to install the sensor is

to be changed, and the proper place is to be selected.

・ If there are the rust and thick coating at a place where the sensor is to be installed on the surface of

piping, remove them.

OTES

4. SELECTION OF INSTALLATION PLACE

4.1 Converter

Regarding the installation place, the following conditions should be taken into consideration：

1) A place where the ambient temperature is -25°C to +50°C, and the humidity is less than 90%RH (without dew).

In order that it can be used for the long time in the stabilized condition, it is recommended that it is to be installed

in the place at normal temperature and humidity as much as possible.

However, if it is less than -10°C inside the converter, the indicator does not operate correctly.

2) A place with little vibration.

3) A place with little dust and corrosive gas.

When unavoidably installing the converter in a place with much corrosive gas, perform the air purge.

4) A place where the sunshine does not hit directly.

5) A place where there is no possibility of this products inking into water.

The waterproof is IP65 (Jet-proof).

6) A place without a possibility of bringing about the inductive interference.

Avoid installing it near to the power apparatus etc.

7) A place where the maintenance and inspection can be easily performed.

4.2 Ultrasonic sensor

To install the ultrasonic sensor, take the following conditions into account：

1) For outdoor installation, take suitable shading and waterproofing measures.

In case of installation in the field, consider the suitable shading and waterproofing measures to avoid the direct

sunshine and rainwater.

2) The piping should be always filled with water.

If the piping is not filled with water, a measurement error may result. Avoid a line where the fluid flows out of

the piping at the time of stopping the flow, and select a place where the piping is always filled with water.

3) The flat piping wall of at least 350mm or more is required.

In order to install a sensor rail, the flat tube wall of at least 350mm or more s required.

(For more than 200mm in nominal diameter, 650mm is required.) Select an appropriate place.

4) Avoid the place where the extremely big vibration, for instance, behind the pump and so on is expected.

The adhesion of the ultrasonic sensor to the tube wall is worsened by the vibration, which may result in poor

OTES

accuracy.

5) Secure the required upstream and downstream straight lengths.

In order to obtain the flow with the axial symmetry, the below-mentioned straight pipe lengths are required.

Otherwise, the accuracy will be out of the accuracy range.

※If the required straight lengths cannot be secured, measurement may go out of our accuracy range.

If a whirlpool or revolving stream is observed, make the straight pipe lengths longer or install a rectifier.

6) In performing the measurement of flow rate of a liquid mixture process, install a sensor downstream

more than 30D away from the point of being mixed.

The measurement made near to the mixing point may cause the fluctuation of output.

7) Other notes

The other notes are shown in Fig. 4.1 to Fig. 4.5. Refer to these figures carefully. Pay attention to them.

Prevent the air bu

bbles from

collecting at the top of pipe by

either installing it upward or

raising the flow velocity.

5. INSTALLATION

5.1 Installation of converter

There are two types of installation available, one is wall mounts type, the other is 2B installation. In either case,

mount it by making the cable entry part downward. If mounted sideward or upward, it may result in causing the

malfunction.

a) Wall mounts type b) 2B mounts type

5.2 Wiring of converter

5.2.1 Notes in wiring

1) The signal cable and output signal cable between the ultrasonic sensor and converter should be separated from

the power supply line or power line etc. Lay the cables not to approach the power apparatus. It is recommended

that the electric wire tube is used for the separation of each cable.

2) When connecting the exclusive cable, insert the wire into the waterproof connector in the back in the receptacle

side, and turn it clockwise securely until it clicks.

3) When connecting cable core to the terminal, insert it to the back of the terminal, but do not fasten the terminal

screw too much. Otherwise, the screw may happen to break.
