Principles and
Requirements
Installation of orice plates
inserted into a circular cross-
section conduit running full
Limitation of pipe size and
Reynolds number
ISO 5167 is applicable
only to ow that remains
subsonic throughout the
measuring section and
where the uid can be
considered single-phase.
It is not applicable to the
measurement of pulsating
ow. It does not cover the
use of orice plates in pipe
sizes less than 50 mm
(2 in.) or more than 1000
mm (39 in.), or for pipe
Reynolds numbers below
5000.
