Liquid hydrocarbons - Dynamic measurement - Proving systems for volumetric meters - Part 2: Pipe provers (ISO 7278-2:1988)

Provides guidance for the design, installation and calibration of these provers. Calculation techniques for use when calibrating and operating provers are detailed in ISO 4267-2. Most of the material is general in that it applies to provers for use with different liquids and types of meters and for proving them in different services. Does not apply to the newer "small volume" or "compact" provers.

Flüssige Kohlenwasserstoffe - Dynamische Messung - Prüfsysteme für volumetrische Meßgeräte - Teil 2: Rohrprüfer (ISO 7278-2:1988)

1.1 Dieser Teil von ISO 7278 behandelt Konstruktion, Installation und Kalibrierung von Rohrprüfern. Die Berechnungstechniken für das Kalibrieren und den Betrieb von Prüfern werden in ISO 4267-2 detailliert beschrieben. 1.2 Dieser Teil von ISO 7278 ist größtenteils allgemein gehalten im Hinblick auf Rohrprüfer, die bei unterschiedlichen Flüssigkeiten und Meßgerät-Typen benutzt und bei unterschiedlichen Betriebsabläufen geprüft werden können. Dieser Teil der Norm ISO 7278 bezieht sich nicht auf die neueren "Kleinvolumen" oder "Compact"Prüfer.

Hydrocarbures liquides - Mesurage dynamique - Systèmes d'étalonnage des compteurs volumétriques - Partie 2: Tubes étalons (ISO 7278-2:1988)

1.1 La présente partie de l'ISO 7278 donne des indications concernant la conception, l'installation et l'étalonnage des tubes étalons. Les calculs techniques nécessaires pour l'étalonnage et l'utilisation des tubes étalons sont détaillés dans l'ISO 4267-2. 1.2 La plupart des sujets abordés dans la présente partie de l'ISO 7278 sont de nature générale : ils s'appliquent aux tubes étalons destinés à être utilisés pour différents liquides et avec différents types de compteurs pour permettre un étalonnage dans différentes conditions de service. Cette méthode ne s'applique pas aux «petits volumes» ou appareils de vérification «compact» de conception récente. 1.3 Les conditions de référence pour la mesure des produits pétroliers sont la température à 15 °C et la pression égale à 101 325 Pa, telles que mentionnées dans l'ISO 5024.  
NOTE -- Dans certains pays, d'autres températures de référence sont utilisées (par exemple 20 °C et 60 °F).

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards bodies (ISO member bodies). T.he work of preparing International
Standards is normally carried out through ISO technical committees. Esch 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. ISO
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 approval before their acceptance as International Standards by
the ISO Council. They are approved in accordance with ISO procedures requiring at
least 75 % approval by the member bodies voting.
International Standard ISO 7278-2 was prepared by Technical Committee ISO/TC 28,
Petroleum produc ts and lubrican ts.
Users should note that all International Standards undergo revision from time to time
and that any reference made herein to any other International Standard implies its
latest edition, unless otherwise stated.
