Table 2.2—Industry Standards for Meter Installation
Meter Type Standard Description
Venturi Meter ISO 5167, Part 1 Installation of orifice plates inserted into a circular cross-section conduit
running full
Limitation of pipe size and Reynolds number
ISO 5167 is applicable only to flow that remains subsonic throughout the
measuring section and where the fluid can be considered single-phase. It is
not applicable to the measurement of pulsating flow. It does not cover the use
of orifice plates in pipe sizes less than 50 mm (2 in.) or more than 1,000 mm
(39 in.), or for pipe Reynolds numbers below 5,000.
ISO 5167, Part 3
ISO 5167-3 describes three Venturi meter variations: machined inlet, rough
cast inlet, and welded sheet metal. Machined inlet meters are available in
diameters up to 10 inches (250 mm), rough cast meters up to 30 inches (800
mm), and welded construction up to 47 in. (1,200 mm).

Pulse Meter
AGA 7, Section 7 Installation of gas turbine meters to include flow direction, meter orientation,
meter run connections, internal surfaces, temperature well location, pressure
tap location, and flow conditioning
Illustrations of recommended installation configurations
Environmental considerations, the use of other devices to improve meter
performance, and precautionary measures
This specification applies to axial-flow turbine flow meters for measurement
of natural gas, typically 2-in. and larger bore diameter, in which the entire gas
stream flows through the meter rotor.

ISO 5167 is applicable only to flow that remains subsonic throughout the

Coriolis
Meter /Mass
Pulse Meter
AGA 11 AGA 11 was developed for the specification, calibration, installation, operation,
maintenance and verification of Coriolis flow meters and is limited to the
measurement of single phase natural gas, consisting primarily of hydrocarbon
gases mixed with other associated gases usually known as “diluents.”
