Current through Vol. 42, No. 7, December 16, 2024

Section 165:65-7-10 - Meter testing facilities and equipment

(a)Test facilities. Each utility furnishing metered water service shall provide the necessary standard facilities, instruments, and other equipment for testing its meters in compliance with this Chapter. Any utility may be excused from this requirement by the Commission provided that arrangements satisfactory to the Commission are made for the test of its meters by another utility or agency equipped to test meters in compliance with this Chapter.

(b)Shop equipment. The utility's meter test shop shall insofar as practicable simulate the actual service conditions of temperature, inlet pressure, and outlet pressure. It shall be provided with all necessary fittings, including a quick acting valve for controlling the starting and stopping of the test and a device for regulating the flow of water through the meter under test within the requirements of this Chapter, and shall include the minimum test equipment as specified in the notes section of the appropriate AWWA Standard in effect for the type of meters to be tested. The overall accuracy of the test equipment and test procedures shall be sufficient to enable the test of service meters within the requirements of this Chapter. In any event, the inherent overall accuracy of the equipment shall permit tests with an overall accuracy of the equipment shall permit tests with an overall error of not greater than three tenths of one percent (.003).

(c)Test measurement standards.

(1)Basic standards. A measuring device for test of meters may consist of a calibrated tank for volumetric measurement or a tank mounted upon scales for weight measurement. If a volumetric standard is used, it shall be accompanied by a certificate of accuracy from any standard laboratory approved by the Commission. If a weight standard is used, the scales shall be tested and calibrated periodically by an approved laboratory and a record maintained of the results thereof.

(2)Size of basic standards. When basic standards are used for meter tests, they shall be of a capacity sufficient to insure adequate determination of accuracy and shall be subject to the approval of the Commission.

(3)Standard meters. A standard meter may be provided and used by any utility for the purpose of testing meters in place. A standard meter shall be tested and calibrated periodically to insure its accuracy within the limits required by this Chapter. In any event, such test shall be made at least once each week while the standard meter is in use and a record of all tests shall be kept by the utility.
