Seal Management - Meter Field Testing
For an effective seal management system it is necessary that:
i) The seals used are tamper proof, that is they cannot be removed and replaced through customers.
ii) The seals should be from such sources in which duplicates should not be available or cannot be manufactured.
iii) The number of seals placed on every meter should not be extremely large, as this will cause logistic problems in managing and auditing the seals.
iv) A proper seal issuing and managing system should be put into place while location of every seal could be traced at any point of time. This covers tracking its total movement beginning from ordering, manufacturing, procurement, record keeping, storage, installation, and series of inspection, removal and disposal.
v) Seals must be stored securely and assigned to individuals responsible for their safekeeping.
vi) Seal audits should be checked routinely, particularly at the time of meter reading and also by audit checks.
