If, upon test, any measuring equipment, including

recording calorimeters, is found to be in error by not more

than two percent (2%), previous recording of such equipment

shall be considered accurate in computing deliveries of gas,

but such equipment shall be adjusted at once to record

accurately.

 

If, upon test, any measuring equipment shall be found

to be inaccurate by an amount exceeding two percent (2%), at

a recording corresponding to the average hourly rate of flow

for the period since the last preceding test, then any

previous recordings of such equipment shall be corrected to

zero error for any period which is known definitely but in

case the period is not known or agreed upon, such correction

shall be for a period extending over one-half of the time

elapsed since the date of last test, not to exceed a period

of sixteen (16) days.

 

11.7 Correction Of Metering Errors -- Failure Of

Meters. In the event a meter is out of service, or

registering inaccurately, the volume of gas delivered shall

be determined:

 

(a) by using the registration of any check

meter or meters, if installed and accurately registering;

or, in the absence of (a);

 

(b) by correcting the error if the percentage

of error is ascertainable by calibration, tests, or

mathematical calculation; or in the absence of both (a) and

(b), then;

 

(c) by estimating the quantity of delivery by

deliveries during periods under similar conditions when the

meter was registering accurately.

 

11.8 Preservation of Metering Records. Transporter

and Shipper shall each preserve for a period of at least

three (3) years all test data, charts and other similar

records.
