National foreword
This British Standard reproduces verbatim ISO 14617-7:2002 and implements
it as the UK national standard.

The UK participation in its preparation was entrusted to Technical Committee
TDW/4, Technical product specification, which has the responsibility to:

A list of organizations represented on this committee can be obtained on
request to its secretary.

Cross-references

The British Standards which implement international publications referred to
in this document may be found in the BSI Catalogue under the section entitled
“International Standards Correspondence Index”, or by using the “Search”
facility of the BSI Electronic Catalogue or of British Standards Online.

This publication does not purport to include all the necessary provisions of a
contract. Users are responsible for its correct application.

Compliance with a British Standard does not of itself confer immunity
from legal obligations.

— aid enquirers to understand the text;

— present to the responsible international/European committee any
enquiries on the interpretation, or proposals for change, and keep the
UK interests informed;

— monitor related international and European developments and
promulgate them in the UK.

Summary of pages

3.1
orifice plate
flow sensor element producing a differential pressure by means of a plate with a specified hole

[IEC 60050-351]

3.2
flow nozzle
flow sensor element producing a differential pressure by means of a convergent device being inserted in a fluid
flow

[IEC 60050-351]

3.3
critical flow nozzle
nozzle of which the geometrical configuration is such that the flow rate remains constant irrespective of the fluid
condition downstream of the nozzle

[IEC 60050-351]

3.4
venturi element
flow sensor element producing a differential pressure by means of a profiled tube generating a change in the
velocity of the fluid flowing through it

[IEC 60050-351]

NOTE The tube consists of a cylindrical entrance part, a convergent part, a cylindrical throat and a divergent part.

3.5
pitot tube
flow sensor element producing a differential pressure by means of two straight tubes mounted in line with the
direction of the fluid movement

[IEC 60050-351]

NOTE The two tubes may be mounted coaxially as a unit.
