GENERAL TERMS AND CONDITIONS

 

 

(d) A specific gravity correction shall be applied to measured

volumes. The specific gravity to be used for such

correction shall be determined at an appropriate location

from a continuous sampling device, by a gravitometer,

chromatograph or other device of standard manufacture and

shall be either (1) recorded using digital recorders or

other mutually agreeable recording device in which case an

arithmetic average (to be determined during the period of

time during which flow was occurring at the location of the

specific gravity recorder) of such record shall be the

specific gravity of the gas being measured, or (2) used for

flow computations in electronic flow computers in which case

the value of the specific gravity being measured will be

used as appropriate in such computations. If a continuous

specific gravity measuring device is not installed or

available at an appropriate location, then specific gravity

shall be determined monthly from a continuous sampling

device or by a mutually agreeable method.

 

(e) The gross heating value shall be determined at an

appropriate location from a continuous sampling device, by a

calorimeter, chromatograph or other device of standard

manufacture and shall be either (1) recorded using digital

recorders or other mutually agreeable recording device in

which case an arithmetic average (to be determined during

the period of time during which flow was occurring at the

location of the gross heating value recorder) of such record

shall be the gross heating value of the gas being measured,

or (2) entered as an input to electronic flow computers in

which case the gross heating value being measured will be

used in the computation of the Btu content of the gas. If a

gross heating value measuring device is not installed or

available at an appropriate location, then the gross heating

value shall be determined monthly from a continuous sampling

device or by a mutually agreeable method.

 

3.3 The provisions of Section 3.2 govern measurement of volumes with

respect to Transporter's measurement equipment. Measurement of

volumes at measurement equipment owned by upstream or downstream

pipelines, shall be in accordance with the requirements of the

appropriate upstream or downstream pipeline.
