3. INSTALLATION

CAUTION

This instrument must be installed by expert engineer or skilled personnel. The procedures described in this chapter are not permitted for operators.

3.1 Piping Design Precautions

IMPORTANT

Please design the correct piping referring to the followings to prevent damage for flow tube and to keep correct measuring.

NOTE

1. Nothing must be inserted or installed in the metering pipe than may interfere with the magnetic field, induced signal voltages, and flow velocity distribution.

2. These straight runs may not be required on the downstream side flowmeter. However, if the downstream valve or other fittings cause channeling on the upstream side, provide a straight run of 2 D to 3 D on the downstream side.

2 D or more

F030101.EPS

IMPORTANT

Please install the flow tube to the location where it is not exposed to direct sunlight and ambient temperature is –10 to + 60°C (14 to 140°F).

(2) Noise Rejection

IMPORTANT

The instrument should be installed away from large electrical motors, transformers and other power sources in order to avoid interference with the measurement.

(3) Length of Straight Run

To keep accurate measuring, JIS B7554 “Electro Magnetic Flow Tubes” explains about upstream piping condition of Magnetic Flow Tubes.

We recommend to our customers about the piping conditions shown in Figure 3.1.1 based on JIS B7554 and our piping condition test data.

(4) Liquid Conductivity

IMPORTANT

Please avoid to install the flow tube at location where liquid conductivity is likely to be nonuniform. Because it is possible to have bad influences to the flow indication by non-uniform conductivity when a chemical liquid is injected from upstream side close to the flow tube. When this occurs, it is recommended that chemical application ports are installed on the downstream side of the flow tube. In case chemicals must be added upstream side, please keep the pipe length enough so that liquid is properly mixed.

(5) Liquid Sealing Compound

IMPORTANT

Please give attention in using Liquid Sealing Compound to the piping, because it brings bad influences to measurement by flowing out and cover the surfaces of electrode and earth-ring.

(6) Service Area

Please select the location where there is enough area to service installing, wiring, overhaul, etc.

(7) Bypass Line

It is recommended to install the Bypass Line to facilitate maintenance and zero adjustment.

IMPORTANT

Please give attention to prevent bad influences or measuring errors from air bubbles that gathers inside measuring pipes.

In case the fluid includes air bubbles, please design the piping that prevent to gather air bubbles. In case valves are installed upstream of the flow tube, it is possible that a valve causes air bubbles, please install the flow tube upstream side of a valve.

Figure 3.1.3 Bypass Line

(8) Supporting the Flow Tube

CAUTION

Please avoid to support only the flow tube, but fix pipes at first and support the flow tube by pipes to protect the flow tube from forces caused by vibration, shock, expansion and contraction through piping. For small sized flow tubes, please provide a mounting base so thet the tubes are fixed in the piping. See the section 3.3 Mounting.

(9) Piping Condition

IMPORTANT

The piping should be designed so that a full pipe is maintained at all times to prevent loss of signal and erroneous readings.

(12) Grounding

IMPORTANT

Improper grounding can have an adverse affect on the flow measurement. Please ensure that the instrument is properly grounded.

The electromotive force of the magnetic flow tube is minute and it is easy to be affected by noise. And also that reference electric potential is the same as the measuring fluid potential. Therefore, the reference electric potential (terminal potential) of the Flow Tube and the Converter/Amplifier also need to be the same as the measuring fluid. And moreover, that the potential must be the same with ground.

Please be sure to ground according to Figure 3.1.7.

3.2 Handling Precautions

WARNING

The Magnetic Flow tube is a heavy instrument. Please be careful to prevent persons from injuring when it is handled.

3.2.1 General Precautions

(1) Precaution for Carrying

The Magnetic Flow Tube is packed tightly. When it is unpacked, please give attention to prevent damages to the flow tube. And to prevent the accident during carry to the installing location, please carry it near the location keeping packed as it delivered.

CAUTION

Earth ring

Grounding resistance 100 Ω or less (10 Ω or less for JIS flameproof type)

In case earth rings are used.

Note; See "3.4.1 Protective Grounding" for information on protective grounding.

(2) Precaution for Shock

CAUTION

Care should be taken not to drop the flow tube or subject it to excessive shock. This may lead to liner damage which will cause inaccurate readings.

(3) Flange Protection Covers

IMPORTANT

Please keep the protection cover (ex. corrugated paper or anything possible to protect) attached with flange except when mounting to the pipe.

(4) Terminal Box Cover

IMPORTANT

3.2.2 Flow Tube Piping

CAUTION

Mis-aligned or slanted piping can lead to leakage and damage to flanges.

•Please correct mis-alignment or slanted piping and

improper distance between mounting flanges before install the flow tube. (Please refer to Figure 3.2.2)

• Inside a pipeline which is newly installed, some

foreign substances (such as welding scrap or wood chips) may exist. Please remove them by flushing piping before mounting the flow tube.

Slant

Mis-alignment

F030202.EPS

Please never leave the terminal box cover open until wiring to prevent insulation deterioration.

(5) Long-term Non-use

IMPORTANT

It is not preferable to leave the flow tube for long term non-use after installation. In case the flow tube is compelled to do that, please take care of the flow tube by the followings.

• Confirmation of Sealing Condition for the Flow Tube

Please confirm the sealing conditions of the terminal

box screw and wiring ports.

In case of the Conduit Piping, please provide the drain plugs or waterproof glands to it to prevent that moisture or water penetrates into the flow tube through the conduit.

• Regular Inspections Please inspect the sealing condition (as above

mentioned) and inside of the terminal box. And when it is suspect that water penetration into the inside flow tube (ex. rain fall), please inspect when it happened.

3. INSTALLATION

3.3.3 Nominal Diameter 50 mm(2˝) to 200 mm(8˝) Wafer Type

IMPORTANT

(1) Mounting Direction

Please mount the Magnetic Flow Tube matching the flow direction of the fluid to be measured with the direction of the arrow mark on the flow tube.

IMPORTANT

NOTE

When installing a size 150mm with JIS F12 (JIS75M) flange, please displace in circumferential direction slightly because the cover of electrode chamber will interfere against the bolts.

(4) Tightening Nuts

Please tighten the bolts according to Torque Values in Table 3.3.5. In case of PVC piping, please select optional code/FRG, use rubber gasket and tighten with the torque value in Table 3.3.6.

CAUTION

In case of PFA lining type as the lining material is Fluorocarbon PFA, it is possible that nuts loose by its character as time passes. Please tighten the nuts regularly. Please be sure to tighten the bolts following prescribed torque values. Please tighten the flange bolts diagonally with the same torque values, step by step up to the prescribed torque value.

If it is impossible to match the direction, please never remodel to change direction of the terminal box. In case the measuring fluid flows against the arrow direction, please refer to the section “Reversing Flow Direction” in the Instruction Manual of AM11 Magnetic Flow Converter.

(2) Mounting Centering Devices

To keep concentricity between the Flow Tube and pipes, centering devices must be used. Pass two through-bolts through the four centering devices (two for each) and lower adjacent holes of both flanges. (Refer to Figure 3.3.4)

Please give attention to the nominal size and flange ratings of the centering devices. (Refer to Table 3.3.7)

(3) Positioning Flow Tube

Position the Flow Tube coming in contact four centering devices with Mini-Flanges. At this time, pay attention to avoid four centering devices come in contact with Housing. In case stud type of throughbolts are used, position them coming in contact four centering devices with thread of the bolts. (Refer to Figure 3.3.4) After positioning the Flow Tube, pass remaining through-bolts to remaining holes.

Nuts

Please use appropriate bolts and nuts according to Process connection.
