5.1 Installation: Unless Seller and Buyers agree otherwise, all

point-of-delivery gas volume measuring equipment, devices and

materials shall be furnished and installed by Seller at Buyer's

expense. All such equipment, devices and materials shall be

owned, maintained and operated by Seller. Buyer may install

and operate check measuring equipment provided it does not

interfere with the use of Seller's equipment.


5.2 Testing Meter Equipment: The accuracy of either Seller's or

Buyer's measuring equipment shall be verified by test, using

means and methods acceptable to the other party, at intervals

mutually agreed upon, and at other times upon request. Notice

of the time and nature of each test shall be given by the

entity conducting the test to the other entity sufficiently in

advance to permit convenient arrangement for the presence of

the representative of the other entity. If, after notice, the

other party fails to have a representative present, the results

of the test shall nevertheless be considered accurate until the

next test. If any of the measuring equipment is found to be

registering inaccurately in any percentage, it shall be

adjusted at once to read as accurately as possible. All tests

of such measuring equipment shall be made at the expense of the

entity conducting the same, except that the other entity shall

bear the expense of tests made at its request if the inaccuracy

is found to be two percent (2%) or less.


5.3 Correction and Adjustment: If at any time any of the measuring

equipment is registering inaccurately by an amount exceeding

two percent (2%) at a reading corresponding to the average

hourly rate of flow, the previous readings of such equipment

shall be corrected to zero error for any period definitely

known or agreed upon, or if not so known or agreed upon, one-

half (1/2) of the elapsed time since the last test. If the

measuring equipment is out of service, the volume of gas

delivered during such period shall be determined:


(a) By using the data recorded by any check measuring

equipment accurately registering; or


(b) If such check measuring equipment is not registering

accurately but the percentage of error is ascertainable by

a calibration test, by using the data recorded, corrected

to zero error; or
