AGA Report No. 7:
Measurement of
Natural Gas by Turbine
Meters
Section 7-
Installation
Specications
Installation of gas turbine
meters to include ow
direction, meter orientation,
meter run connections, internal
surfaces, temperature well
location, pressure tap location,
and ow conditioning
Illustrations of recommended
installation congurations
Environmental considerations,
the use of other devices to
improve meter performance,
and precautionary measures.
This specication
applies to axial-ow
turbine owmeters for
measurement of natural
gas, typically 2-in. and
larger bore diameter, in
which the entire gas stream
ows through the meter
rotor.
