Section 103-763 - Facilities and Equipment for Testing

Each utility shall maintain or designate a meter shop for the purpose of inspecting, testing and repairing meters. The shop shall be open for inspection by authorized representatives of the ORS at all reasonable times, and the facilities and equipment, as well as the methods of measurement and testing employed, shall be subject to the approval of the commission. The accuracy of the test equipment and test procedures shall be such that the overall error will not exceed .03%.

1. Working Standards.

A. Each meter shop maintained or designated by a utility shall have at least one calibrated tank available for volumetric measurement or a tank mounted upon scales for weight measurement. The tank shall be of sufficient capacity to insure an acceptable determination of the accuracy of the utility's meters.

B. The utility may use a portable test meter, approved by the commission for use as a standard, for the purpose of testing meters.

C. Reasonable care must be exercised in the use and handling of standards to assure that their accuracy is not disturbed. Each standard shall be accompanied at all times by a certificate or calibration card, duly signed and dated, on which are recorded the corrections required to compensate for errors found at the customary test points at the time of the last previous test.

2. Meter Prover. The accuracy of all provers and methods of operating them will be established from time to time by a representative of the ORS. All alterations, accidents, or repairs which might affect the accuracy of any meter prover or the method of operating it shall be promptly reported in writing to the ORS.
