recording devices in which case the temperature at

which gas was measured for the period of such record

shall be the arithmetic average of the record during

the period of time during which gas was flowing, or

(2) used for on-site flow computations in electronic

flow computers in which case the instantaneous

measurement of temperature will be used in such

computations.

 

(d) Each month a specific gravity correction shall be

applied to measured volumes based upon the specific

gravity determined or sampled during that month.

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) Each month a gross heating value correction shall be

applied to measured volumes based upon the gross

heating value determined or sampled during that

month. 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

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.
