Measurement of liquid flow in closed conduits - Method by collection of the liquid in a volumetric tank (ISO 8316:1987)

Measurement of liquid flow in closed conduits - Method by collection of the liquid in a volumetric tank (ISO 8316:1987)

The specified measuring methods are built upon the determination of the volume of liquid collected in a volumetric tank in a known time interval. Deals in particular with the measuring apparatus, the procedure, the method for calculating the flow-rate and the assessment of uncertainties associated with the measurements.

Durchflußmessung von Flüssigkeiten in geschlossenen Leitungen - Verfahren der Volumenbestimmung mit einem Meßbehälter (ISO 8316:1987)

Diese Internationale Norm legt Verfahren zur Durchflußmessung von Flüssigkeiten in geschlossenen Leitungen fest, bei dem der Volumendurchfluß durch das Messen der Flüssigkeit in einem Volumenmeßbehälter innerhalb eines bekannten Zeitraumes bestimmt wird. Sie behandelt die Meßeinrichtung, die Durchführung, das Verfahren der Berechnung des Durchflusses und die Meßunsicherheit dieser Messungen.

Mesure de débit des liquides dans les conduites fermées - Méthode par jaugeage d'un réservoir volumétrique (ISO 8316:1987)

La présente Norme internationale spécifie la méthode de mesurage d'un débit de liquide en conduite fermée par la détermination du volume de liquide parvenant dans une capacité jaugée au cours d'un certain laps de temps. Elle traite en particulier de l'appareillage de mesure, du mode opératoire, du mode de calcul du débit et de la détermination des incertitudes sur les résultats de mesure. Telle qu'elle est décrite, la méthode peut être appliquée à tout liquide, à condition
a) que sa pression de vapeur saturante soit suffisamment faible pour que la perte de liquide par évaporation dans la capacité jaugée n'affecte pas la précision de mesure recherchée;
b) que sa viscosité soit suffisamment faible pour ne pas fausser ou retarder exagérément la mesure du niveau dans la capacité jaugée;
c) qu'il ne soit ni agressif, ni toxique.
Il n'y a pas de limite de principe à l'emploi de la présente
  méthode, mais pour des raisons pratiques, celle-ci n'est générale
  II n’y a pas de limite de principe à l’emploi de la présente
  méthode, mais pour des raisons pratiques, celle-ci n’est généralement
  utilisée que pour des débits inférieurs à 1,5 m3/s
  environ et dans des installations fixes de laboratoire. II existe cependant
  une variante de cette méthode qui utilise comme réservoir jaugé
  un bassin de retenue, naturel ou artificiel, mais cette application ne fait
  pas l’objet de la présente Norme internationale.
Du fait de la grande précision qu’elle peut atteindre, cette méthode
  est souvent utilisée comme méthode primaire pour étalonner
  d’autres méthodes ou appareils de mesure du débit-volume
  ou du débit-masse, sous réserve pour ce dernier que la masse volumique
  du liquide soit connue avec précision. Si l’installation de mesure
  par jaugeage volumétrique est utilisée pour les besoins de la
  métrologie légale, elle doit être agréée par
  les services métrologiques nationaux. De telles installations sont alors
  soumises à des inspections périodiques, à intervalles fixes.
  En l’absence de service métrologique national, une certification
  des mesures physiques do! base (longueurs, temps et températures) et
  une analyse des erreurs selon les prescriptions de la présente Norme
  internationale et de I’ISO 5168 peuvent tenir lieu d’agrément
  au regard de la métrologie légale. L’annexe A fait partie
  intégrante de la présente Norme internationale. Les annexes B
  à E ne sont données toutefois qu’à titre d’information.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards bodies (ISO member bodies). The 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.
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 8316 was prepared by Technical Committee ISO/TC 30,
Measurement of fluid flow in closed conduits.
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.

Measurement of fluid flow by means of pressure differential devices inserted in circular cross-section conduits running full - Part 3: Nozzles and Venturi nozzles (ISO 5167-3:2022)
SIST EN ISO 5167-3:2023

This document specifies the geometry and method of use (installation and operating conditions) of nozzles and Venturi nozzles when they are inserted in a conduit running full to determine the flowrate of the fluid flowing in the conduit.
This document also provides background information for calculating the flowrate and is applicable in conjunction with the requirements given in ISO 5167‑1.
This document is applicable to nozzles and Venturi nozzles in which the flow remains subsonic throughout the measuring section and where the fluid can be considered as single-phase. In addition, each of the devices can only be used within specified limits of pipe size and Reynolds number. It is not applicable to the measurement of pulsating flow. It does not cover the use of nozzles and Venturi nozzles in pipe sizes less than 50 mm or more than 630 mm, or where the pipe Reynolds numbers are below 10 000.
This document deals with
a) three types of standard nozzles:
1)    ISA 1932[1] nozzle;
2)    the long radius nozzle[2];
3)    the throat-tapped nozzle
b) the Venturi nozzle.
The three types of standard nozzle are fundamentally different and are described separately in this document. The Venturi nozzle has the same upstream face as the ISA 1932 nozzle, but has a divergent section and, therefore, a different location for the downstream pressure tappings, and is described separately. This design has a lower pressure loss than a similar nozzle. For all of these nozzles and for the Venturi nozzle direct calibration experiments have been made, sufficient in number, spread and quality to enable coherent systems of application to be based on their results and coefficients to be given with certain predictable limits of uncertainty.
[1]   ISA is the abbreviation for the International Federation of the National Standardizing Associations, which was superseded by ISO in 1946.
[2] The long radius nozzle differs from the ISA 1932 nozzle in shape and in the position of the pressure tappings.

Measurement of fluid flow by means of pressure differential devices inserted in circular cross-section conduits running full - Part 5: Cone meters (ISO 5167-5:2022)
SIST EN ISO 5167-5:2023

This document specifies the geometry and method of use (installation and operating conditions) of cone meters when they are inserted in a conduit running full to determine the flow rate of the fluid flowing in the conduit.
As the uncertainty of an uncalibrated cone meter might be too high for a particular application, it might be deemed essential to calibrate the flow meter in accordance with Clause 7.
This document also provides background information for calculating the flow rate and is applicable in conjunction with the requirements given in ISO 5167‑1.
This document is applicable only to cone meters in which the flow remains subsonic throughout the measuring section and where the fluid can be considered as single-phase. Uncalibrated cone meters can only be used within specified limits of pipe size, roughness, β, and Reynolds number, Re. This document is not applicable to the measurement of pulsating flow. It does not cover the use of uncalibrated cone meters in pipes sized less than 50 mm or more than 500 mm, or where the pipe Reynolds numbers are below 8 × 104 or greater than 1,2 × 107.
A cone meter is a primary device which consists of a cone-shaped restriction held concentrically in the centre of the pipe with the nose of the cone upstream. The design of cone meter defined in this document has one or more upstream pressure tappings in the wall, and a downstream pressure tapping positioned in the back face of the cone with the connection to a differential pressure transmitter being a hole through the cone to the support bar, and then up through the support bar.
Alternative designs of cone meters are available; however, at the time of writing, there is insufficient data to fully characterize these devices, and therefore, these meters shall be calibrated in accordance with Clause 7.

Measurement of fluid flow by means of pressure differential devices inserted in circular cross-section conduits running full - Part 6: Wedge meters (ISO 5167-6:2022)
SIST EN ISO 5167-6:2022

This document specifies the geometry and method of use (installation and operating conditions) of wedge meters when they are inserted in a conduit running full to determine the flow rate of the fluid flowing in the conduit.
NOTE 1    As the uncertainty of an uncalibrated wedge meter can be too large for a particular application, it could be deemed essential to calibrate the flow meter according to Clause 7.
This document gives requirements for calibration which, if applied, are for use over the calibrated Reynolds number range. Clause 7 could also be useful guidance for calibration of meters of similar design but which fall outside the scope of this document.
It also provides background information for calculating the flow rate and is applicable in conjunction with the requirements given in ISO 5167‑1.
This document is applicable only to wedge meters in which the flow remains subsonic throughout the measuring section and where the fluid can be considered as single-phase. Uncalibrated wedge meters can only be used within specified limits of pipe size, roughness, β (or wedge ratio) and Reynolds number. It is not applicable to the measurement of pulsating flow. It does not cover the use of uncalibrated wedge meters in pipes whose internal diameter is less than 50 mm or more than 600 mm, or where the pipe Reynolds numbers are below 1 × 104.
NOTE 2    A wedge meter has a primary element which consists of a wedge-shaped restriction of a specific geometry. Alternative designs of wedge meters are available; however, at the time of writing there is insufficient data to fully characterize these devices, and therefore these meters are calibrated in accordance with Clause 7.

Measurement of gas flow by means of critical flow nozzles (ISO 9300:2022)
SIST EN ISO 9300:2022

This document specifies the geometry and method of use (installation in a system and operating conditions) of critical flow nozzles (CFNs) used to determine the mass flow rate of a gas flowing through a system basically without the need to calibrate the CFN. It also gives the information necessary for calculating the flow rate and its associated uncertainty.
This document is applicable to nozzles in which the gas flow accelerates to the critical velocity at the minimum flowing section, and only where there is steady flow of single-phase gas. When the critical velocity is attained in the nozzle, the mass flow rate of the gas flowing through the nozzle is the maximum possible for the existing inlet condition, while the CFN can only be used within specified limits, e.g. the CFN throat to inlet diameter ratio and Reynolds number. This document deals with the toroidal- and cylindrical-throat CFNs for which direct calibration experiments have been made in sufficient number to enable the resulting coefficients to be used with certain predictable limits of uncertainty.

Measurement of fluid flow by means of pressure differential devices inserted in circular cross-section conduits running full - Part 4: Venturi tubes (ISO 5167-4:2022)
SIST EN ISO 5167-4:2022

This document specifies the geometry and method of use (installation and operating conditions) of Venturi tubes[1] when they are inserted in a conduit running full to determine the flow rate of the fluid flowing in the conduit.
This document also provides background information for calculating the flow rate and is applicable in conjunction with the requirements given in ISO 5167-1.
This document is applicable only to Venturi tubes in which the flow remains subsonic throughout the measuring section and where the fluid can be considered as single-phase. In addition, Venturi tubes can only be used uncalibrated in accordance with this standard within specified limits of pipe size, roughness, diameter ratio and Reynolds number, or alternatively they can be used across their calibrated range. This document is not applicable to the measurement of pulsating flow. It does not cover the use of uncalibrated Venturi tubes in pipes sized less than 50 mm or more than 1 200 mm, or where the pipe Reynolds numbers are below 2 × 105.
This document deals with the three types of classical Venturi tubes:
a) “as cast”;
b) machined;
c) fabricated (also known as “rough-welded sheet-iron”).
A Venturi tube consists of a convergent inlet connected to a cylindrical throat which is in turn connected to a conical expanding section called the divergent section (or alternatively the diffuser). Venturi nozzles (and other nozzles) are dealt with in ISO 5167-3.
NOTE       In the USA the classical Venturi tube is sometimes called the Herschel Venturi tube.

Hydrometry - Minimum performance requirements and test procedures for water monitoring equipment - Devices for the determination of flow - Part 2: Closed conduit instrumentation
SIST EN 17694-2:2023

This document specifies general requirements, minimum performance requirements and test procedures for instrumentation used to measure either volumetric flow-rate and/or total volume passed of water in closed conduits. It covers all closed conduit instrument (CCI) technologies intended to operate in closed pressurized pipes and partially filled pipes. Requirements are expressed in volumetric units which may be converted to mass using the density of the water.
It is recognized that for some CCIs certain tests cannot be carried out.
The data obtained from the testing of CCIs in accordance with the requirements of the Measuring Instruments Directive [1] or EN ISO 4064-1 [2] can be used to meet, in part, the requirements specified in this document. However, for the avoidance of doubt, compliance with the requirements of this document does not equate to compliance with the requirements of the Measuring Instruments Directive or EN ISO 4064-1.
