This part of ISO 5167 specifies the geometry and method of use (installation and operating conditions) of
orifice plates when they are inserted in a conduit running full to determine the flowrate of the fluid flowing in
the conduit.
This part of ISO 5167 also provides background information for calculating the flowrate and is applicable in
conjunction with the requirements given in ISO 5167-1.
This part of ISO 5167 is applicable to primary devices having an orifice plate used with flange pressure
tappings, or with corner pressure tappings, or with D and D/2 pressure tappings. Other pressure tappings
such as vena contracta and pipe tappings have been used with orifice plates but are not covered by this part
of ISO 5167. This part of ISO 5167 is applicable only to a flow which remains subsonic throughout the
measuring section and where the fluid can be considered as 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 or
more than 1 000 mm, or for pipe Reynolds numbers below 5 000.
