2. OPERATING CONDITIONS
To maintain the stated high accuracy and long
service life of the meter, make sure that the operating
flowrate, pressure, temperature, etc., are held within
the ratings specified. These ratings are stated on
the meter preamplifier nameplate (tag). Read them
carefully before you place the meter in service.
1. BEFORE YOU BEGIN
1.1 Confirming the Specifications
() When received, the meter should be thoroughly inspected for indication of rough handling during transit.
(2) Product code number and ratings are stated on the meter nameplate. Make sure that the ratings shown
conform to your particular specifications.
1.2 Transit Considerations
() It is desirable that the meter be transported to the installation site in the shipping container used for transit
from the factory.
(2) During transportation, exercise care to avoid impact shock and rainwater.
1.3 Storage Considerations
() The meter can best be stored in the shipping container used for transit from the factory.
(2) The place of storage should meet the following requirements:
- Free from rain and water
- Free from vibration and impact shocks
- With least temperature and humidity variation (around 25°C and 65% R.H.)
(3) A meter that has once been place in service for any length of time should be washed clean to remove
residue metered material completely from its inner walls before storage. Waterproofing the cable entrance
should also be taken into considerations.
CAUTION: Unauthorized modification will invalidate the specifications.
