Appendix
A Purge Fittings
Keeping purge fittings sealed
If the sensor has purge fittings, they should remain sealed at all times.
After a purge plug is removed, the sensor case should be purged with a
dry, inert gas (such as argon or nitrogen), and resealed. See Case
purging procedure, page 56.
Purging the case protects internal components. Before Micro Motion
ships a sensor from the factory, it purges the sensor case. If you never
loosen or remove the fittings, you do not have to be concerned about
them.
