Industry Standard Compliance
To ensure measurement accuracy, flow runs and turbine meter runs must be installed in accordance with the industry
standards listed in Table 2.2—Industry Standards for Meter Installation, page 30 . For a complete list of industry stan-
dards used in the development of flow rate and fluid property calculations, see Table 1.4—Flow Rate Standards, page
16 and Table 1.5—Fluid Property and Energy Flow Calculations, page 17.
Table 2.2—Industry Standards for Meter Installation
Meter Type Standard Description
Orifice Meter AGA 3, Section 2.6 Specifications for orifice meters (to include beta ratios)
Installation requirements for orifice plates, meter tubes, flow conditioners, and
thermometer wells
This standard is also distributed under the following names: API MPMS Chapter
14.3, Part 2; ANSI/API 14.3, Part 2-3100; and GPA 8185, Part 2.
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 1000 mm
(39 in.), or for pipe Reynolds numbers below 5000.
ISO 5167, Part 2 Specifies orifice plates that can be used with flange pressure tappings, corner
pressure tappings, D and D/2 pressure tappings.
API MPMS Chapter
21.1, Section 1.7
Installation of electronic gas measurement devices and associated
communications, gauge/impulse lines, and cabling
API MPMS Chapter
21.1, Section 1.8
Requirements for calibrating and verifying the accuracy of electronic gas
measurement devices
ASME MFC-14M Specifies low-flow orifice meters smaller than 2 inch pipe size, that can be
used with flange taps and corner taps.
Nominal pipe sizes (1/2 inch to 1-1/2 inch only)
Beta ratio from 0.1 to 0.75
Suitable for single-phase fluids only
Subsonic flow only
Not suitable for pulsating flow
Cone Meter NuFlo* Cone Meter
User Manual,
Sections 2 through 5
System components, impulse tubing considerations, best practices for
installation, installation procedures/diagrams for liquid and gas service
ISO 5167, Part 1 Installation of orifice plates inserted into a circular cross-section conduit

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 1000 mm
(39 in.), or for pipe Reynolds numbers below 5000.
ISO 5167, Part 5
ISO 5167-5 describes the background information for calculating the flow rate
and is applicable in conjunction with the requirements given in ISO 5167-1.
Uncalibrated cone meters can only be used within specified limits of pipe size,
roughness, β, and Reynolds number. This part of ISO 5167 is not applicable to
the measurement of pulsating flow. It does not cover the use of uncalibrated
cone meters in pipes sized less than 50 mm or more than 500 mm, or where
the pipe Reynolds numbers are below 8 × 10
