The objective of this Technical Report is to provide guidance on the use
of ISO 5167:2003 (all parts). ISO 5167:2003 is an International Standard for flow
measurement based on the differential pressure generated by a constriction
introduced into a circular conduit (see ISO 5167-1:2003, 5.1). It presents a
set of rules and requirements based on theory and experimental work undertaken
in the field of flow measurement.
