1 Handling and Lifting Safety

CAUTION

To reduce the risk of personal injury or damage to equipment, follow all
lifting and handling instructions.

• Handle all parts carefully to prevent damage. Whenever possible,

transport the system to the installation site in the original shipping
container.

• PTFE-lined sensors are shipped with end covers that protect it from both

mechanical damage and normal unrestrained distortion. Remove the
end covers just before installation.

• Keep the shipping plugs in the conduit ports until you are ready to

connect and seal them. Appropriate care should be taken to prevent
water ingress.

• The sensor should be supported by the pipeline. Pipe supports are

recommended on both the inlet and outlet sides of the sensor pipeline.
There should be no additional support attached to the sensor.

• Use proper PPE (Personal Protection Equipment) including safety glasses

and steel toed shoes.

• Do not lift the meter by holding the electronics housing or junction box.

• The sensor liner is vulnerable to handling damage. Never place anything

through the sensor for the purpose of lifting or gaining leverage. Liner
damage can render the sensor useless.

• Do not drop the device from any height.

1.1 Lifting lugs

CAUTION

If provided, use the lifting lugs on each flange to handle the Magnetic
Flowmeter when it is transported and lowered into place at the installation
site. If lifting lugs are not provided, the Magnetic Flowmeter must be
supported with a lifting sling on each side of the housing.

• Standard pressure 3-in. through 48-in. flanged magnetic flowmeters

come with lifting lugs.

3 Location and Position

3.1 Environmental considerations

To ensure maximum transmitter life, avoid extreme temperatures and
excessive vibration. Typical problem areas include the following:

• High-vibration lines with integrally mounted transmitters

• Tropical/desert installations in direct sunlight

• Outdoor installations in arctic climates

Remote mounted transmitters may be installed in the control room to
protect the electronics from the harsh environment and to provide easy
access for configuration or service.

3.2 Upstream and downstream piping

To ensure specified accuracy over widely varying process conditions, install
the sensor with a minimum of five straight pipe diameters upstream and two
pipe diameters downstream from the electrode plane.

Figure 3-1: Upstream and downstream straight pipe diameters

A. Five pipe diameters (upstream)
B. Two pipe diameters (downstream)
C. Flow direction

Installations with reduced upstream and downstream straight runs are
possible. In reduced straight run installations, the meter may not meet
accuracy specifications. Reported flow rates will still be highly repeatable.

3.3 Flow direction

The sensor should be mounted so that the arrow points in the direction of
flow.
