COUNCIL DIRECTIVE of 26 July 1971 on the approximation of the laws of the Member States relating to gas volume meters (71/318/EEC)

THE COUNCIL OF THE EUROPEAN COMMUNITIES,

Having regard to the Treaty establishing the European Economic Community, and in particular Article 100 thereof;

Having regard to the proposal from the Commission;

Having regard to the Opinion of the European Parliament1;

Having regard to the Opinion of the Economic and Social Committee2;

Whereas in the Member States the construction and methods of control of gas volume meters are subject to mandatory provisions which differ from one Member State to another and consequently hinder trade in such instruments ; whereas it is therefore necessary to approximate these provisions;

Whereas the Council Directive of 26 July 19713 on the approximation of the laws of the Member States relating to provisions both for measuring instruments and methods of metrological control has laid down the EEC type approval and EEC initial verification procedures ; whereas, in accordance with that Directive, the technical requirements for the design and functioning of gas volume meters should be laid down;

HAS ADOPTED THIS DIRECTIVE:

Article 1

This Directive applies to the following gas volume meters: 1. Volumetric meters: - meters with deformable walls;

• - 

  meters with rotary pistons.

• 2. 

  Non-volumetric meters: - turbine meters.

Article 2

Those meters which may bear EEC marks and symbols are described in the Annex to this Directive. They shall be subject to EEC type approval and shall be submitted to EEC initial verification.

Article 3

No Member State may refuse, prohibit, or restrict the placing on the market or entry into service of gas volume meters bearing the EEC type approval symbol and the EEC initial verification mark.

Article 4

• 1. 

  Member States shall put into force the laws, regulations and administrative provisions needed in order to comply with this Directive within eighteen months of its notification, and shall forthwith inform the Commission thereof.

ANNEX

CHAPTER I

• A. 

  DEFINITION OF CERTAIN TERMS USED IN THE ANNEX

• 1. 

  Range of load

The range of load of a gas meter is bounded by the maximum flow Qmax and the minimum flow Qmin.

• 2. 

  Cyclic volume of a volumetric meter

"Cyclic volume V of a volumetric meter" means the volume of gas corresponding to a cycle of operation of the meter, that is to say to the whole of the movements of the moving components of the meter at the end of which all these components except the indicator and the intermediate transmissions return, for the first time, to their original position.

It is calculated by multiplying the value of the volume represented by a complete revolution of the test element, by the transmission ratio of the measuring device to the index...
