3.2 Handling Precautions
WARNING
The magnetic flowmeter 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 flowmeter. When
moving the magnetic flowmeter, 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 flowmeter.
3.2.1 General Precautions
(1) Precaution during Transportation
The magnetic flowmeter is packed tightly. When
it is unpacked, pay attention to prevent damaging
the flowmeter. 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 magnetic flowmeter, use the lifting rings
(eye bolts or eye plates) as in Figure 3.2.1.
Never lift it using a bar passed through the magnetic
flowmeter as this damages the liner severely.

(2) Avoid Shocks from Impact
CAUTION
Care should be taken not to drop the flowmeter or
expose it to excessive shock. In particular, be careful
not to subject the flange 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) in place over
the flange except when mounting the flowmeter to the
pipe.
(4) Terminal Box Cover
IMPORTANT
As it is possible that the insulation will deteriorate, do
not 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 flowmeter unused
for a long term after installation. If this situation is
unavoidable, take care of the flowmeter by observing
the following.
Confirmation of sealing conditions for the
flowmeter
Confirm that the terminal box screw and electrical
connections are well sealed. Equip the conduit piping
with drain plugs or waterproof glands to prevent moisture
or water from penetrating into the flowmeter 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 flowmeter, perform
supplementary inspections.
