2. HANDLING PRECAUTIONS
2.3 Storage Precautions
If the instrument is to be stored for a long period of
time after delivery, observe the following points.
᭹ The instrument should be stored in its original
packing condition in the storage location.
᭹ Select a storage location that fulfils the following
conditions:
• A place where it will not be exposed to rain or
water
• A place subject to minimal vibrations or shocks
• Temperature and humidity levels should be as
follows:
Temperature: -30 to 70
°C
Humidity: 5 to 80% RH (no condensation)
The preferred ambient temperature and
humidity levels are 25
°C and approximately
65% RH.
᭹ If the AXF magnetic flowmeter is transferred to the
installation site and stored without being installed,
its performance may be impaired due to the infiltra-
tion of rainwater and so forth. Be sure to install and
wire the AXF magnetic flowmeter as soon as
possible after transferring it to the installation
location.
2.4 Installation Location
Precautions
Select the installation location with consideration to the
following items to ensure long-term stable operation of
the instrument.
᭿ Ambient Temperature:
Avoid installing the instrument in locations with
constantly fluctuating temperatures. If the location is
subject to radiant heat from the plant, provide heat
insulation or improve ventilation.
᭿ Atmospheric Condition:
Avoid installing the instrument 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.
᭿ Vibrations or Shocks:
Avoid installing the instrument in a place subject to
shocks or vibrations.
᭿ Explosion protected type:
Explosion protect types can be installed in hazard-
ous areas according to the types of gases for which
they are certified. See the description in Chapter 8
