(a) Before being installed for use by a customer, every gas service meter, whether
new, repaired, or removed from service for any cause shall be in good order and,
except as provided in paragraph (b) of this rule, shall be adjusted to be correct to
within one percent when passing gas at 20 percent of its rated capacity at one-
half inch water column differential.
(b) New rotary displacement type gas service meters in sizes having a rated
capacity of more than 5,000 cubic feet per hour at a differential not to exceed two
inches water column shall be tested and calibrated at the factory in accordance
with recognized and accepted practices. These meters shall also be adjusted to
be correct within two percent slow and one percent fast when passing gas at ten
percent of its rated capacity and shall be adjusted to be correct within one
percent slow and one percent fast when passing gas at 100 percent of its rated
capacity. Prior to reuse of a rotary displacement type meter that has been
removed from service, the meter shall pass the same testing criteria as a new
meter.
