Current through Register 2024 Notice Reg. No. 38, September 20, 2024
N.1.
Test Liquid. The test liquid shall be carbon dioxide in a compressed liquid
state.
N.2. Vaporization and Volume
Change. Care shall be exercised to reduce vaporization and volume changes to a
minimum. When testing by weight, the weigh tank and transfer systems shall be
precooled to liquid temperature prior to the start of the test to avoid the
venting of vapor from the vessel being weighed.
N.3. Test Drafts.
N.3.1. Gravimetric Test. Weight test drafts
shall be equal to at least the amount delivered by the device in two minutes at
its maximum discharge rate.
N.3.2.
Transfer Standard Test. When comparing a meter with a calibrated transfer
standard, the test draft shall be equal to at least the amount delivered by the
device in two minutes at its maximum discharge rate.
N.3.3. Volumetric Prover Test Drafts. Test
drafts shall be equal to at least the amount delivered in one minute at normal
discharge rate.
N.4.
Testing Procedures.
N.4.1. Normal Tests. The
"normal" test of a device shall be made at the maximum discharge flow rate
developed under the conditions of installation. Any additional tests conducted
at flow rates down to and including one-half of the sum of the maximum
discharge flow rate and the rated minimum discharge flow rate shall be
considered normal tests.
N.4.2.
Special Tests. Any test except as set forth in N.4.1. shall be considered a
special test. Tests shall be conducted, if possible, to evaluate any special
elements or accessories attached to or associated with the device. A device
shall be tested at a minimum discharge rate of:
(a) not less than the minimum rated capacity
or 20 percent of the maximum rated discharge rate of the device, whichever is
less, or
(b) the lowest discharge
rate practicable under the conditions of installation.
"Special" tests may be conducted to develop any
characteristic of the device anticipated under the conditions of installation
as circumstances require.
N.4.3. Density. Temperature and pressure of
the metered test liquid shall be measured during the test for the determination
of density or volume correction when applicable. Table 1, contained in this
Article, shall apply.
N.4.4.
Automatic Temperature or Density Compensation. If a device is equipped with an
automatic temperature or density compensator, the compensator shall be tested
by comparing the quantity indicated or recorded by the device (with the
compensator connected and operating) with the actual delivered quantity. Table
1, contained in this Article, shall apply.
