WARNING

Installation of the magnetic owmeter must be performed by expert engineer or skilled personnel. No operator shall be permitted to perform procedures

relating to installation.

Installation Location Precautions

Select the installation location with consideration to the

following items to ensure long-term stable operation of

the product.

 Ambient Temperature:

Avoid installing the product in locations with constantly uctuating temperatures. If the location is subject to radiant heat from the plant, provide heat insulation or improve ventilation.

 Atmospheric Condition:

Avoid installing the product in a corrosive atmosphere. In situations where this is unavoidable, consider ways to improve ventilation and to prevent rainwater from entering and being retained in the conduit pipes.

 Vacuum:

In the case of PTFE lining, avoid the negative pressure inside the measuring pipe.

 Vibrations or Shocks:

Avoid installing the product in a place subject to shocks or vibrations.

3.1 Piping Design Precautions

IMPORTANT

Design piping correctly, referring to the following to prevent damage to sensors and to assure accurate

measuring.

NOTE

This section describes the remote sensor as an example. The same attention must be paid to the integral owmeter.

(1) Location

IMPORTANT

Install the owmeter in a location where it is not exposed to direct sunlight. The minimum ambient temperature is limited by the minimum uid temperature of the sensor (the lining). For more information, read the applicable general specication as listed inTable 1.1. The owmeter may be used in an ambient humidity where the relative humidity ranges from 0 to 100%. However, avoid long-term continuous operation at relative humidity 95% or higher.

Installation

(2) Noise Avoidance

IMPORTANT

The owmeter should be installed away from electrical motors, transformers, and other power sources in order to avoid interference with measurement. When installing two or more magnetic owmeters, provide a distance of at least 5D (D is size of model code) each other. If diameters of them are different, let D be the larger one.

*1: Do not install anything in the vicinity that may interfere

with the magnetic eld, induced signal voltages, or ow velocity distributions of the owmeter.

*2: A straight run may not be required on the downstream

side of the owmeter. However, if a downstream valve or other tting causes irregularity or deviation in ows, provide a straight run of 2D to 3D on the downstream side.

*3: The valves shall be mounted on the downstream side so

that deviated ows do not occur in the sensor and to avoid

startup from an empty condition.

*4: In case the piping conditions are compounded, install

on the straight pipe section where the upstream part is sufciently rectied.

(5) Precautions for Use of Liquid Sealing

Compounds

IMPORTANT

Care must be taken in using liquid sealing compounds on the piping, as it may have a negative inuence on the ow indications by owing out and covering the

surfaces of an electrode or grounding ring. In particular,

care must be taken if a liquid sealing compound is used in the case of vertical piping.

(6) Service Area

Select locations where there is adequate space to service installing, wiring, overhauling, etc.

(7) Bypass Line

It is recommended to install a bypass line to facilitate maintenance and zero adjustment.

(4) Maintaining Stable Fluid Conductivity

IMPORTANT

Do not install the owmeter where uid conductivity tends to become uneven. If chemicals are fed near the upstream side of a magnetic owmeter, they may affect the ow rate’s indications. To avoid this situation, it is recommended that the chemical feed ports be located on the downstream side of the owmeter. If it is unavoidable that chemicals must be fed on the upstream side, provide a sufcient length of straight run (approximately 50D or more) to ensure the proper mixture of uids.

 Pipes must be fully lled with liquids.

IMPORTANT

It is essential that pipes remain fully lled at all times, otherwise ow rate indications may be affected and

measurement errors may be caused.

Piping shall be designed so as to maintain the interior of the sensor lled with uids. Vertical mounting is effective in such cases as when uids tend to separate or solid matter may be precipitated. When employing vertical mounting, direct the uids from the bottom to the top to ensure that the pipes remain fully lled.

WARNING

The magnetic owmeter is a heavy product. Be careful that no damage is caused to personnel through accidentally dropping it, or by exerting excessive force on the magnetic owmeter. When moving the magnetic owmeter, always use a trolley and have at least two people carry it.

NOTE

This section describes the remote sensor as an example. The same attention must be paid to the integral owmeter.

3.2.1 General Precautions

(1) Precaution during Transportation

The magnetic owmeter is packed tightly. When it is unpacked, pay attention to prevent damaging the owmeter. To prevent accidents while it is being transported to the installing location, transport it to the site in its original packing.

(5) Long-term Non-use

CAUTION

IMPORTANT

In order to lift a magnetic owmeter that is tted with eyebolts, proceed as in Figure 3.2.1. Never lift it using a bar passed through the sensor as this damages the lining severely. When lifting the magnetic owmeter in vertical position, eyebolts (or eyenuts and bolts) are necessary. Attach them to the ange bolt holes, and then lift the magnetic owmeter.

Vertical positionHorizontal position

It is not desirable to leave the owmeter unused for a long term after installation. If this situation is unavoidable, take care of the owmeter by observing the following.

 Conrmation of sealing conditions for the

owmeter

Conrm that the terminal box screw and cable entries are well sealed. Equip the conduit piping with drain plugs or waterproof glands to prevent moisture or water from penetrating into the owmeter through the conduit.

 Regular inspections

Inspect the sealing conditions as mentioned above, and the inside of the terminal box at least once a year. Also, due to rain, etc. when it is suspected that water may have penetrated into the inside of the owmeter, perform

supplementary inspections.

3.2.2 Flowmeter Piping

Figure 3.2.1 Lifting Flowmeter

(2) Avoid Shocks from Impact

CAUTION

Care should be taken not to drop the owmeter or expose it to excessive shock. In particular, be careful not to subject the ange surface to shock. This may lead to lining damage which will result in inaccurate

readings.

(3) Flange Protection Covers

IMPORTANT

Keep the protective covering (i.e. the corrugated cardboard or other cushioning material) and the attached particle board (when PTFE lining is specied) in place over the ange except when mounting the owmeter to the pipe.

(4) Terminal Box Cover

IMPORTANT

CAUTION

Misaligned or slanted piping can lead to leakage and damage to the anges.

(1) Correct any misaligned or slanted piping, and any

gaps that may exist between mounting anges before installing the owmeter (see Figure 3.2.2).

Slanted

Figure 3.2.2 Slanted and Misaligned Flowmeter Piping

(2) Inside a newly installed pipeline, there may be some

foreign substances such as residue from welding or wood chips. Remove them by ushing the piping before mounting the owmeter. This prevents the lining from being damaged, as well as the occurrence

of erroneous measured signals resulting from foreign

substances passing through the sensor during

measurement.

Misaligned

As it is possible that the insulation will deteriorate, do not open the terminal box cover until it is time to wire it.

3.3 Integral Flowmeter and Remote Sensor Installation

WARNING

• All gaskets used for piping of magnetic owmeters should be prepared by customers except in some

cases.

• To avoid damaging the ange surface of the sensor, do not use spiral wound gaskets.

NOTE

• The tightening torque of gasket varies depending on the type and the external dimensions of the lining and the gasket. The tightening torque values and the corresponding gasket types are indicated in the tables of this section. The dimensions the gasket used for piping-side ange should be decided by

referring to Subsection 3.3.3.

• For uids capable of potentially permeating PTFE linings (such as nitric acid, hydrouoric acid, or sodium hydrate at high temperatures), do not use the PTFE lining type.

• The PTFE lining has a structure adhering PTFE to the metal inner face of the sensor. When install to the piping, be careful not to bring unequal stress or torque to the PTFE lining.

• For the PTFE lining, it is recommended to be installed with grounding rings, or to be installed with short pipes at upstream and downstream sides.

3.3.1 Size 25 to 200 mm (1 to 8 in.), Wafer Type

IMPORTANT

Use bolts and nuts in compliance with the ange ratings. When stud-type through-bolts are used, be sure the outside diameter of the shank is smaller than that of the thread ridge. Be sure to choose a gasket with inner and outer diameters that does not protrude inside the piping (read Subsection 3.3.3). If the inner diameter of the gasket is too large, or outer diameter of the gasket is too small, uid leakage may result.

(1) Mounting Direction

Mount the owmeter so that the ow direction of the uid to be measured is in line with the direction of the arrow mark on the owmeter.

IMPORTANT

If it is impossible to match the direction of the arrow mark, the direction of the cable entry can be changed.

Read Section 3.5.

In case the uid being measured ows against the arrow direction, change the value from “Forward” to “Reverse” at the parameter “Flow direct”. Read the user's manual of the applicable communication type (for AXW/AXW4A/AXG1A) or the hardware/software edition

(for AXFA11) as listed in Table 1.1.

Display Menu Path (AXW/AXW4A/AXG1A):

(2) Mounting Centering Devices

To maintain concentricity of the owmeter with the pipes, install centering devices. Use the appropriate centering devices according to the nominal diameter and the ange

ratings.

• Size: 25 to 40 mm (1 to 1.5 in.)

Pass two through-bolts through the adjacent holes of both anges and position the owmeter so that the Mini-anges and the centering devices come in close contact with each other. In case stud-type through-bolts are used, position them in such a way that the centering devices come in contact with the bolt threads. Pass the other through-bolts through the other holes. See Figure 3.3.2 for the mounting.

• Size: 50 to 200 mm (2 to 8 in.)

From the process piping side, pass two through-bolts through the adjacent two holes (the lower two holes for horizontal mounting) of both of the anges and the four centering devices (two for each bolt). Be careful to prevent the four centering devices from coming into contact with the sensor housing. In case stud-type through-bolts are used, position them in such a way that the four centering devices come in contact with the bolt threads. Pass the other through-bolts through the other holes. See Figure 3.3.3 for the mounting.

The gaskets (supplied by customer) used for connection with customer pipes differ by the presence or absence of grounding device (grounding ring) and the specied specications. Be sure to use the gaskets in compliance with the ange ratings and uid specication. Install the gaskets as the followings. Be sure to choose gaskets with inner and outer diameters that do not protrude inside the piping by referring to

Subsection 3.3.3.
