CAUTION!
DO NOT remove these plugs.
The meter is factory sealed with a dry nitrogen gas fill and if moisture is allowed to enter the
meter casing it will cause damage. The plugs should only be removed to purge the meter casing
in the event that the primary measuring tube fails.
If it is suspected that the primary measuring tube has failed, de-pressurise the meter and
remove it from service, as soon as it is safe to do so.
