3.1 Piping Design Precautions

IMPORTANT
Design piping correctly, referring to the following to prevent damage to owtubes and to assure accurate measuring.
(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 owtube (the lining). For more information, refer to Chapter 6 “OUTLINE”. 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 above 95%.

*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 owtube and to avoid startup from an empty condition.
(4) Maintaining Stable Fluid Conductivity
2D
2D
F0301.ai
(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.
(3) Required Lengths of Straight Runss
To maintain accurate measurement, see JIS B7554 “Electro Magnetic Flowmeters” which explains the requirements for upstream piping conditions of magnetic owmeters. Based on JIS B7554 “Electro Magnetic Flowmeters” and our piping condition test data, we recommend the piping conditions as shown in the following
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) to ensure the proper mixture of uids.

(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.
Block valve
(9) Mounting Positions
• 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 owtube 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.

(8) Supporting the Flowmeter
CAUTION
Do not secure the owmeter separately to prevent the vibrations, shocks, and expansion and contraction forces of the piping from affecting it. Fix the pipeline or its anges rst, then let them support the owmeter. For vertical, mounting, make sure that the weight of piping does not weigh on the owmeter. To release the load from tightening the owmeter to the pipeline, set a expansive pipe in the downstream side.
• Avoid air bubbles.
IMPORTANT
If air bubbles enter a measurement pipe, ow rate indications may be affected and measurement errors may be caused.
In cases where uids contain air bubbles, piping must be designed to prevent them from accumulating in the measurement pipe of a owtube.
If a valve exists near the owmeter, try to mount the owmeter on the valve’s upstream side in order to prevent a possible reduction of pressure inside the pipe, thereby avoiding the possibility of air bubbles.

(2) Avoiding 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 liner damage which will result in inaccurate readings.
WARNING
The magnetic owmeter is a heavy instrument. 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, forklift, or crane and have at least two people carry it.

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.
CAUTION
When lifting the owtube, use the lifting rings (eye bolts or eye plates) as in Figure 3.2.1. Never lift it using a bar passed through the owtube as this damages the liner severely.
(3) Flange Protection Covers
IMPORTANT
Keep the protective covering (i.e. the corrugated cardboard or other cushioning material) in place over the ange except when mounting the owmeter to the pipe.
(4) Terminal Box Cover
IMPORTANT
As it is possible that the insulation will deteriorate, do not remove the wrapping of the terminal box nor open the terminal box cover until it is time to wire it.
(5) Long-term Non-use
IMPORTANT
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.
IM 01E25D11-01EN
<3.INSTALLATION>
3-4
• Conrmationofsealingconditionsforthe owmeter
Conrm that the terminal box screw and wiring ports 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 owmeter perform supplementary inspections.
3.2.2 FlowmeterPiping
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 (refer to Figure 3.2.2).
3.3 MountingProcedures
CAUTION
When attaching optional grounding rings to the owtube with lining material natural hard rubber or uorocarbon PTFE, gaskets must be placed between each grounding ring and the owtube. Fluid leakage will happen without these gaskets. These gaskets are to be supplied by customer. Do not forget those gaskets also when ordering and attaching the grounding rings later additionally.
NOTE
The tightening torque value varies depending on the type of lining and gasket as shown in the tables in this section.
IMPORTANT
Use bolts and nuts in compliance with the ange ratings. When choosing the gaskets, be sure to choose sheet gaskets designed to t for ange standard.
