Each time the Tank Seal Data is changed, the Seal ID is incremented. This Seal
ID will be recorded by the W&M official.
If someone learns the W&M password and makes changes to the Tag Seals, the
Seal ID will be incremented and no longer match the Seal ID recorded by the
W&M official. In this manner the W&M official is able to detect unauthorized
tampering with the Tag Seals.
When a Tank is sealed, the user cannot configure or edit any process variable
scaling, engineering unit, volume correction, vessel characteristic, vapor
characteristic, or strap table parameters.
