Section 69-09-01-13 - Gas meter accuracy requirement1. Installation test. Every gas service meter, whether new or repaired, or that has been removed from the service for any cause, shall be in good order and shall be correct to within two percent before being installed for the use of any customer. However, a utility which has less than one thousand customers and which has no facilities for opening meter cases and adjusting the mechanism may put a meter back into service, unless it is found to be in error by more than two percent or appears otherwise to be in poor condition. 2.Method of testing. For the purpose of determining compliance with this section, the registration of a displacement meter shall be determined by one test at a rate of flow of approximately one-fifth of the rated capacity of that meter and one test at a rate of flow of approximately the rated capacity of the meter. The tests at the two rates shall agree within two percent. The accuracy of the meter at the lower rate of flow shall be considered as its accuracy in determining compliance with subsection 1 and for the purpose of computing refunds. All tests to determine the accuracy of any gas service meter shall be made with a meter prover, unless, because of the unusual capacity or construction of the meter, such method of test shall be considered impracticable and another method of test shall have been approved by the commission.
