If intermediate or long-term storage of equipment is required, it is
recommended that the equipment be stored in accordance with the
following:
a. Within the original shipping container .
b. S tored in a sheltered area, preferably a warm, dry, heated
warehouse.
c. Ambient temperature of 70° F (21° C) nominal, 109° F (43° C)
maximum,
45° F (7° C) minimum.
d. Relative humidity 45% nominal, 60% maximum, 25% minimum.
Upon removal from storage a visual inspection should be conducted
to verify the condition of equipment is "as received".

To safeguard against damage during transit, transport the instrument to
the installation site in the same container used for transport ation from the
factory if circumstances permit.
Upon removal of the instrument from storage, a visual inspection should
be conducted to verify its "as-received" condition.
A. Location
For proper operation the Model 1305 must be mounted within 6 degrees of
true vertical, with the inlet connection at the bottom and the outlet at the
top. The use of a level is recommended to assure vertical positioning.
Piping must be adequately supported to prevent undue strain on the
flowmeter.
B. Piping Arrangement
It is recommended that bypass piping be installed around the flowmeter so
it may be isolated from the process line for servicing and cleaning.
Refer to Figure 2-1 for a typical installation.
Do not allow the float to fall out of the metering tube. A damaged
float will affect the accuracy of the meter. Be careful not to break the
tube by pulling on it at an extreme angle or applying excessive force.
Failure to drain the flowmeter when isolated in a bypass loop may
result in tube breakage caused by thermal expansion of the process
liquid.

C. Panel Mounting
If panel mounting is used refer to Figure 2-2 for the required cutout.
