FD ISO/TR 9464, X10-155 (10/2023)

The objective of this document is to provide guidance on the use of the ISO 5167:2022 series. ISO 5167:2022 is an International Standard for flow measurement based on the differential pressure generated by a constriction introduced into a circular pipe (see ISO 5167-1:2022, 5.1). It presents a set of rules and requirements based on theory and experimental work carried out in the field of flow measurement. For a more detailed description of the scope, refer to ISO 5167-1:2022, Clause 1. Definitions and symbols applicable to this document are given in ISO 5167-1:2022, Clauses 3 and 4. Neither ISO 5167-1:2022 nor this document gives detailed theoretical information, for which reference is made to general works on fluid flow.
