2.2 Transportation and Storage
Precautions
If the instrument is to be stored for a long period of
time after delivery, observe the following points.
(1) The instrument should be stored in its original
packing condition in the storage location.
(2) Select a storage location that fulfi ls 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:-40 to +80°C
Humidity:5 to 100% RH (no condensation)
The preferred ambient temperature and
humidity levels are +25°C and approximately
65% RH.
(3) If the digitalYEWFLO vortex fl owmeter is
transferred to the installation site and stored
without being installed, its performance may
be impaired due to the infi ltration of rainwater
and so forth. Be sure to install and wire the
digitalYEWFLO vortex fl owmeter as soon as
possible after transferring it to the installation
location.
(4) The vortex fl 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 vortex fl owmeter. When
moving the vortex fl owmeter, always use a
trolley and have at least two people carry it.
