Rule 38.5.2513 - METER TESTS
Current through Register Vol. 18, September 20, 2024
(1) Sample Tests. The utility shall select a sample of five percent of all of its meters in service each year for testing the accuracy of its registration.
(2) Fast Meters. If, upon test of any meter, the meter is found to have an average error of more than two percent fast, the utility shall follow ARM 38.5.2505(8) to reconcile the billing error.
(3) Dead Meters. If a meter is found not to register for any period, the utility shall compute the water used by taking the average of the water used for the meter-reading period preceding and the meter-reading period following the date when the meter was found to be dead, which amount shall be assumed to be the amount of water used by the customer during the billing period in which the meter was found dead. Exceptions will be made to this rule if the facts clearly show that the above method does not give the correct consumption for the period.
