BS EN 14154-1-2005 + A2-2011 PDF

Full title and description

STB BS EN 14154-1:2005 + A2:2011 — Water meters — Part 1: General requirements. British-adopted European Standard (BS EN) of EN 14154-1:2005 including Amendment A2 (2011). Specifies general and metrological requirements, dimensions and certification procedures for water meters intended for cold potable and heated water service, covering mechanical, electronic and hybrid meter technologies and ancillary devices when subject to metrological control.

Abstract

This standard defines the general metrological, dimensional and marking requirements for water meters used in residential, commercial, light industrial and industrial applications. It applies to meters irrespective of measuring principle (mechanical, electronic or combined), includes rules for cartridge and exchangeable metrological units, sets requirements for ancillary electronic devices where they are under metrological control, and provides the basis for conformity assessment and certification under relevant measurement directives.

Scope

Applies to water meters intended for metering the volume of clean cold potable water and heated water in fully charged, closed conduits for residential, commercial, light industrial and industrial uses. The document specifies dimensional, metrological and marking requirements, certification procedures and requirements for electronic ancillary devices under metrological control. It covers meters regardless of measuring technology and includes provisions for cartridge meters and meters with exchangeable metrological units; detailed test methods and installation conditions are referenced in the related parts of the EN 14154 series.

Key topics and requirements

• Definition of meter types, applications and intended fluid (cold potable and heated water).
• Metrological requirements (accuracy classes, measurement ranges, permissible errors and verification principles).
• Dimensional requirements and standardised interfaces for in-line, concentric and cartridge meters (physical envelope, connection sizes, DN ranges).
• Requirements for electronic ancillary devices when subject to metrological control (displaying/recording integrated volume, interfaces, power and protection).
• Marking, labelling and information to be supplied with the meter (manufacturer, type, accuracy class, flow direction, serial number).
• Certification and conformity assessment procedures relevant to European measuring-instruments directives.
• References and interfaces to Parts 2 (installation), 3 (test methods) and 4 (additional functionalities) of the EN 14154 series.
• Requirements covering cartridge and exchangeable metrological units and corresponding connection interfaces.

Typical use and users

Used by water meter manufacturers (design and type approval), conformity assessment and calibration laboratories, certification and notified bodies, utilities and water companies specifying procurement requirements, regulatory authorities implementing measurement legislation, and installers/contractors ensuring meters meet required installation and marking practices.

Related standards

Closely related items include EN 14154-2 (Installation and conditions of use), EN 14154-3 (Test methods and equipment), EN 14154-4 (Additional functionalities), and the EN ISO 4064 series (ISO 4064 — Water meters), the latter having replaced the EN 14154 series in many national adoptions. The document is also used in the context of European measuring-instruments directives (e.g., MID / Directive 2004/22/EC and subsequent measurement legislation).

FAQ

Q: What is this standard?

A: EN 14154-1:2005 + A2:2011 (published as BS EN 14154-1:2005 + A2:2011 when adopted in the UK) is the Part 1 general-requirements document of the EN 14154 series for water meters; it sets metrological, dimensional and conformity requirements for water meters and certain ancillary devices.

Q: What does it cover?

A: It covers general and metrological requirements for water meters used with cold potable and heated water, including dimensions, marking, certification procedures, and metrological requirements for electronic ancillary devices when those devices are under metrological control. Detailed test methods and installation rules are contained in Parts 2 and 3 of the series.

Q: Who typically uses it?

A: Manufacturers, conformity-assessment bodies and test laboratories, utilities and procurement teams, water industry engineers, regulatory authorities and installers specifying or verifying compliance of meters for commercial and residential distribution systems.

Q: Is it current or superseded?

A: Superseded/withdrawn. EN 14154-1:2005+A2:2011 has been withdrawn and replaced by the EN ISO 4064 series (notably EN ISO 4064-1:2014 and subsequent revisions). Official national withdrawal/replacement occurred in 2014; users should adopt the corresponding EN ISO 4064 edition required by their national authority or regulatory framework.

Q: Is it part of a series?

A: Yes. EN 14154 is a multi-part series; Part 1 covers general requirements, Part 2 covers installation and conditions of use, Part 3 covers test methods and equipment, and Part 4 covers additional functionalities. Much of the EN 14154 content has since been integrated into or superseded by the EN ISO 4064 series (ISO 4064).

Q: What are the key keywords?

A: Water meter, potable water, metrology, flow measurement, accuracy class, cartridge meter, exchangeable metrological unit, certification, ancillary electronic device, BS EN, EN 14154.
