Section R. 460.2353 - Retirement of meters

(1) Meters must be retired from service whenever abnormal conditions affecting accuracy cannot be corrected for economic or other reasons. Examples of such conditions are basic defects due to manufacture, design, or excessive damage. Meters may also be retired due to obsolescence, unavailability of repair parts, or other reasons.

(2) Notwithstanding the provisions of any other rule, meters that are found to be overregistering must be repaired or replaced within 6 months of the discovery of the error unless a different period is approved by the commission.
