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.
