GENERAL TERMS AND CONDITIONS
14.8 Measurement. Questar may install orifice, turbine, positive
displacement, ultrasonic meters or other measurement devices. They will be
installed and operated in accordance with then-approved AGA and API
recommendations, where available.
(a) Orifice Meters. All orifice meters will be installed and gas
volumes computed according to the standards prescribed in AGA Report No. 3,
Part 2 and API Chapter 14.3.
(b) Turbine Meters/Positive Displacement Meters. All turbine
meters will be installed and gas volumes computed according to the standards
prescribed in AGA Report No. 7 and AGA ANSI B109.3.
(c) Ultrasonic Meters. All ultrasonic meters will be installed
and gas volumes computed according to the standards prescribed in AGA Report
(d) Square Root Error. If unacceptable square root error or
gauge line error is caused by an interconnecting company's equipment or by a
shipper on the interconnecting company pipeline, Questar will refuse to
accept gas from the interconnecting pipeline at that location until the
problem is corrected. Unacceptable square root error is defined to be equal
to or greater than 0.5%. If there is a disagreement over the degree of error
between Questar and the operator of the source, a mutually agreeable
independent third-party will be requested to determine the source and degree
of error. The party deemed responsible for the pulsation source will incur
all costs for the consultation and the installation of remedial devices or
filtering equipment, as necessary.
(e) New Standards. Questar may adopt the most recent edition of:
API Chapter 14.3; AGA Report No. 3, Part 2; AGA Report No. 7; and AGA Report
