 Chapter 15-23. NATURAL GAS

  Section 15-2352. METERING TESTS  

Latest version.

  • 2352.1Only authorized representatives of a gas corporation shall remove and set meters. Each gas corporation shall keep a record of the dates that each meter is set in and removed from service.

    2352.2The test of any meter or associated devices, or both, shall consist of a comparison of its accuracy with the accuracy of the standards prescribed by the National Bureau of Standards or other methods specified in this chapter.

    2352.3Testing equipment shall be of sufficient capacity and ranges to test meters or associated devices, or both, under the conditions specified in § 2360.

    2352.4Bell provers may be used to test diaphragm, rotary, and turbine type meters. A prover that is used to test rotary and turbine type meters shall be properly automated and have a satisfactory readout. The test shall consist of passing a specific volume of air through the prover and the meter. The accuracy or proof is either read or calculated from the prover scale or the readout.

    2352.5Approved working standards other than bell provers may be used to test diaphragm, rotary, and turbine type meters.

    2352.6The meter to be tested shall be connected to the approved working standard so that the same volume of air, either under pressure or vacuum, passes through both.

    2352.7The uncorrected accuracy shall be calculated or read directly from the readout on the working standard. Corrections shall be made for pressure and temperature differentials between the meter under test and the working standard to determine the corrected accuracy.
