BS EN 24006:1993:1991 Edition

This International Standard defines the terms to be used in the field of measurement of fluid flow in closed conduits, and gives the corresponding symbols.

It has been found necessary to exclude terms which come under the following categories:

1. terms which are self-evident;

2. terms which do not apply specifically to this field, in particular those referring more specifically to flow in open channels (see ISO 772);

3. terms referring to very specific methods of measure¬ment which cannot be the subject of standardization.

Defines terms and symbols including basic fluid mechanics and calculation of uncertainties. Also defines all common types of flowmeter and their operating principle, with illustrations.
