14.10 ORIFICE METERS - Orifice meters and electronic flow

computers will be installed and Gas quantities measured

in accordance with the standards prescribed in API

Manual of Petroleum Measurement Standards, Chapter 14 -

Section 3 and Chapter 21 - Section 1.

 

14.11 NEW MEASUREMENT TECHNIQUES - If at any time a new method

or technique is developed with respect to Gas

measurement or the determination of the factors used in

such Gas measurement, such new method or technique may

be substituted by mutual agreement between Transporter

and the interconnecting Operator.

 

14.12 CORRECTION OF METERING ERRORS -

 

a. If during any test of the measurement equipment, an

adjustment or calibration error is found that

results in an incremental adjustment to the

calculated flow rate, through the meter tube, in

excess of one per cent (1%) of the adjusted flow

rate (using the adjusted flow rate as the per cent

error equation denominator), then the previous

recordings of such equipment will be corrected to

zero (0) error for any period during which the error

existed that is either known definitely or mutually

agreed to, or if such time is not ascertainable,

then back one-half (1/2) the time elapsed since the

date of the last calibration, not to exceed sixteen

(16) Days.

 

b. If during any test of the measuring equipment, an

adjustment or calibration error is found that

results in an incremental adjustment to the

calculated flow rate, through the meter tube, that

does not exceed one per cent (1%) of the adjusted

flow rate (using the adjusted flow rate as the per

cent error equation denominator) then the previous

recordings will be considered to be accurate for

quantity determination purposes, but such equipment

will be adjusted to record accurately.
