GENERAL TERMS AND CONDITIONS (cont'd)

 

 

3.2 Measurement of Volume (c) - (con't)

 

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) 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.
