GENERAL TERMS AND CONDITIONS

(continued)

 

 

(1) At intervals of not more than six (6) Months, by means of

an instrument of standard manufacture accepted in the

industry for this purpose using a sample of Gas from the

Gas stream.

 

(2) By means of an instrument of standard manufacture

accepted in the industry for this purpose installed at a

point to measure the specific gravity of the Gas stream

from which Gas is being delivered.

 

(vi) The compressibility ratio factor "s" used in

computing the volume of Gas delivered through a

turbine meter or a positive displacement meter

shall be determined by the equation s = (Fpv)2,

in which "Fpv" is the supercompressibility

factor determined as described in subparagraph

(iv) of this subsection (b).

 

(vii) In determining the flowing temperature factor,

supercompressibility factor, and compressibility

ratio factor "s" for use in computing the volume

of Gas delivered through a meter, the flowing

gas temperature for only the period(s) of time

that Gas was flowing through the meter shall be

used.

 

4.3 All flow, measuring, testing and related equipment shall

be of standard manufacture and type approved by

Transporter. If applicable, Transporter or Shipper may

install check measuring equipment, provided that such

equipment shall be so installed as not to interfere with

the operations of the Transporter. Transporter, or

Shipper, in the presence of the other party, shall have

access to measuring equipment at all reasonable times,

but the reading, calibrating, and adjusting thereof and

the changing of charts shall be done by the Transporter

of the facilities. Transporter or Shipper shall have the

right to be present at the time of the installing,

reading, cleaning, changing, repairing, inspecting,

testing, calibrating or adjusting done by the Transporter

of the measuring equipment. The records from such

measuring equipment shall remain the property of the

Transporter, but upon request, the other party may

request records, and charts, together with calculations

there from for inspection, subject to return within (30)

Days after receipt thereof. Reasonable care shall be

exercised in the installation, maintenance and operation

of the measuring equipment so as to avoid any inaccuracy

in the determination of the volume of Gas received and

delivered. The accuracy of all measuring equipment shall

be verified by the Transporter at reasonable intervals,

and if requested, in the presence of representatives of

the other party, but neither Transporter nor Shipper

shall be required to verify the accuracy of such

equipment more frequently than once in any thirty (30)

Day period. If either party at any time desires a

special test of any measuring equipment, it will promptly

notify the other party and the parties shall then

cooperate to secure a prompt verification of the accuracy

of such equipment.
