GENERAL TERMS AND CONDITIONS

3. MEASUREMENT PROCEDURES

 

3.1 Atmospheric Pressure. The atmospheric pressure shall be assumed

to be fourteen and seventy-three hundredths (14.73) pounds per square inch.

 

 

3.2 Orifice Meters. When orifice meters are used, the gas delivered

shall be measured with meters constructed and installed, and whose

computations of volume are made, in accordance with the provisions of AGA

Measurement Committee Report No. 3 of the American Gas Association as printed

and revised September, 1978, (AGA Report No. 3), with any subsequent

amendments or revisions which are acceptable to MRT.

 

3.3 Positive or Turbine Meter. When positive or turbine meters are

used, the gas delivered shall be measured with meters constructed and

installed, and whose computations are made, in accordance with the provisions

of AGA Measurement Committee Report No. 6 when positive meters are employed,

and AGA Measurement Committee Report No. 7 when turbine meters are used, with

any subsequent amendments or revisions of either report which are acceptable

to MRT.

 

3.4 Electronic Transducers and Flow Computers. When electronic

transducers, flow computers, gas chromatographs and/or other electronic

equipment are used, the gas delivered shall have its volume, mass and/or

energy content computed in accordance with the standards of the American Gas

Association as promulgated by AGA Measurement Committee Report Nos. 3, 5, 6,

7, NX-19 and 8, with any subsequent amendments or revisions of the reports

which are acceptable to MRT. The parties specifically agree to accept the use

of these electronic devices in lieu of mechanical devices with charts.

 

3.5 Determination of Heating Value and Specific Gravity. The heating

value of the gas shall be expressed in Btu per dry cubic foot of gas at 14.73

Psia and 60 degrees Fahrenheit (101.325 kPa and 15.6 degrees C and dry). The

method used and the frequency of measurement for both the heating value and

the specific gravity shall be at MRT's sole option provided they are in

general use within the natural gas transmission industry.
