26.12 Electronic Measurement may be utilized in lieu of calculations based upon charts and chart

recorders, and may be used with orifice, positive, or turbine meters. When Electronic Measurement

is utilized, the process variables necessary for the flow calculation are generated, where possible,

by transmitters located on or near the flow computer. Where process variables are not available

from transmitters located on or near the flow computer, necessary values will be supplied by

prospective application of the arithmetic or other average of values taken from generally accepted

analytical instrument(s). Where Electronic Measurement is utilized, the flow calculations generated

and electronic records based upon such calculations shall be accepted and utilized in substitution

for charts and other documentary records. If the transmitters used to provide process variables

are found to be out of calibration when tested then the requirements of paragraph 2.17 shall be

followed in determining the volume of gas tendered.
