Measurement of conductive liquid flow in closed conduits - Methods using electromagnetic flow-meters (ISO 6817:1992)

Describes the principle and main design features of industrial electromagnetic flowmeters (both a.c. and pulsed d.c. versions) for the measurement of flow-rate in a closed conduit running full. Covers their installation, operation, performance and calibration.

Durchflußmessung von leitfähigen Flüssigkeiten in geschlossenen Leitungen - Verfahren mit magnetisch-induktiven Durchflußmeßgeräten (ISO 6817:1992)

Diese Internationale Norm beschreibt das Meßprinzip und die Hauptbestandteile eines magnetisch-induktiven Durchflußmeßgerätes und behandelt den Einbau, die Arbeitsweise, die Ausführung und die Kalibrierung von industriell genutzten Geräten. Diese Norm legt keine Sicherheitsanforderungen für den Gebrauch solcher Geräte unter sicherheitstechnisch bedeutsamen Bedingungen fest. Sie behandelt nicht die Anwendung von Geräten zur Messung von Flüssigmetallen und magnetisch verschmutzten Schlämmen und die Benutzung im medizinischen Bereich.

Mesure de débit d'un fluide conducteur dans les conduites fermées - Méthode par débitmètres électromagnétiques (ISO 6817:1992)

La présente Norme internationale décrit le principe et les principes fondamentaux de conception des débitmètres électromagnétiques mesurant le débit d'un liquide conducteur dans une conduite fermée remplie. Elle traite de leur installation, de leur fonctionnement, de leur performance et de leur étalonnage. La présente Norme internationale ne spécifie aucune règle de sécurité pour l'emploi des débitmètres dans les conditions environnementales dangereuses et ne s'applique pas au mesurage des boues perméables magnétiquement ni aux usages médicaux. Elle traite des débitmètres en version courant alternatif et courant continu pulsé.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. international organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the
work. IS0 collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an Inter-
national Standard requires approval by at least 75 % of the member
bodies casting a vote.
International Standard IS0 6817 was prepared by Technical Committee
ISO/TC 30, Measurement of fluid flow in closed conduits, Sub-Committee
SC 5, Electromagnetic flowmeters.
The first edition cancels and replaces ISO/TR 6817:1980, of which it
constitutes a technical revision.
Annexes A and B of this International Standard are for information only.
