(2) A turbine meter, designed, installed, maintained and

operated as recommended in the latest issue of American

Gas Association Transmission Measurement Committee Report

6.2(a) The volume of Gas delivered to Seller or redelivered to or

for the account of Customer shall be calculated by means of

either an electronic flow computer, or by the processing of

meter charts, in either case in the following manner:

 

(1) When the measuring equipment is an orifice meter, the

flow of Gas through the meter shall be computed in the

manner recommended in AGA Report No. 3, properly using

all factors set forth therein.

 

(2) When the measuring equipment is a turbine meter, the volume

of Gas delivered through the meter shall be computed in the

manner recommended in AGA Report No. 7, properly using all

factors set forth therein.

 

(3) When the measuring equipment is a positive displacement

meter, the volume of Gas delivered through the meter shall

be computed by properly applying, to the volume delivered

at flowing Gas pressures and temperatures, correction

factors for (i) absolute static pressure, (ii) flowing Gas

temperature, and (iii) compressibility ratio.

 

(b) The volume of Gas injected or withdrawn hereunder shall be

computed using the standards and factors determined as follows:
