Verification of Water meters
Water meters are subject to verification in Austria.
The first verification of a new instrument is called initial verification. The verification of an unverified instrument is a new verification. Verification within the validity period is called reverification.
The Measuring Instruments Directive (MID) has been applied in all EU Member States since October 30, 2006.
This Directive regulates the launching onto the market of measuring instruments liable to verification through conformity assessment procedures. Water meters are included in the MID. Therefore they may be put into use for the first time without further national type approval or initial verification. The assessment of the conformity is equivalent to the initial verification.
Modules B+D, B+F and Conformity assessment procedure H1 are applicable to water meters.
See Measuring Instruments Directive MI-001.
Water meters which do not fall under this directive are subject to the national regulations as before. Besides the national pattern approval there exists also an EEC-type approval under the European Economic Area Agreement (EEA-Agreement).
New and subsequent verification of water meters are at any rate subject to national regulations. They are performed by accredited/authorized verification bodies.
The reverification period for water meters is 5 years. An extension of that period is not possible at present.
