Water meters - Part 2: Installation and conditions of use

This document specifies criteria for selection of water meters, installation requirements and the first operation of new or repaired meters to ensure accurate constant measurement and reliable reading of the meter.
In applications where a water meter is legally required to conform to the requirements of the Measuring Instruments Directive, this document may be used to demonstrate conformity.
Where legal national requirements exist they shall in all cases take precedence over or supplement the specifications given in this part of this document.

Wasserzähler - Teil 2: Einbau und Voraussetzungen für die Verwendung

Dieses Dokument legt Kriterien für die Auswahl von Wasserzählern, Bedingungen für deren Einbau und die Inbetriebnahme von neuen oder reparierten Zählern fest, um eine genaue konstante Messung und zuverlässige Ablesung der Zähler zu gewährleisten.
Bei Anwendungen, bei denen gesetzlich gefordert wird, dass ein Wasserzähler den Anforderungen der EU-Messgeräterichtlinie MID entspricht, kann das vorliegende Dokument als Konformitätsnachweis verwendet werden.
Dort, wo gesetzliche nationale Anforderungen vorliegen, haben sie auf alle Fälle Vorrang vor den Bestimmungen dieses Teils des vorliegenden Dokuments, oder sie bilden eine Ergänzung dazu.

 combination meters, care should be taken that 'cross-over' flowrates are different from (and below) normal operating flowrates;  available supply pressure;  physical and chemical characteristics of the water;  possibility of deposition of substances from solution within the water meter;  acceptable pressure loss across the meter;  available space and pipe work to install the meter and fittings;  sustainability of the power supply of the water meter (where applicable). 4.2 Information to be provided by the manufacturer The manufacturer shall supply sufficient information to enable the correct choice and installation of a meter: such that influencing factors shall not lead to either failure or non conformance with the specified metrological characteristics. This is particularly important for hydraulic disturbances. Specifically, the manufacturer shall determine the influence factors, which affect the indicating error and state of the individual meter design. For each influence factor the manufacturer shall state the relevant rated operating conditions applicable to the meter. 4.3 Meters operating in parallel or in a group For meters operating in parallel, means shall be provided so that the unserviceability of one or more meters within a group shall not cause the remaining meters to operate at a flowrate in excess of each individual meter’s limit of operation. In order to ensure that water meters of different types will operate satisfactorily in parallel, the individual characteristics of all the meters operating in parallel shall be compatible. This may be achieved, for example, by grouping them according to pressure loss, flowrate range and maximum working pressure. However, the installation conditions for each type shall be respected. For meters operating in parallel and multiple meter operation, the possibilities of interaction between one meter or meter type and another, to the detriment of their life and accuracy shall be considered; for example pressure surges and vibration.
