Conn. Gen. Stat. § 16-259: Inspection of meters.

Upon petition of any person and the payment of a fee of ten dollars for each meter, the Public Utilities Regulatory Authority may cause to be inspected any meter used in measuring electricity, gas or water supplied to the petitioner. The authority may prescribe such limits of variation from accurate registration by such meters as it determines to be reasonable. The company supplying electricity, gas or water through any such meter shall reimburse the petitioner for the inspection fee if the meter is found not to register accurately within the limit of variation so prescribed, and the company may not again use the meter until it is corrected and approved by the authority.
