Measuring instruments allow accuracy of measurement – water meters, gas meters, electricity meters, etc. - and play a more and more significant role in today's society, by raising the industry and consumers' awareness on their actual consumption and making them more environmentally responsible.
In the field of measurement, CEN develops standardization deliverables for heat, gas, and water meters, whereas the electricity sector is covered by CENELEC.

European Legislation and mandates
European Standards are developed in the context of European legislation and sometimes come in direct support to particular Directives or Regulations.
In 2004, the Council and the European Parliament adopted the MID, which applies to the design, manufacturing and conformity assessment of measuring instruments. The directive covers 10 categories of measuring instruments and mainly addresses precision, reliability and security of instruments. Standards developed in compliance with the MID are recognised as 'harmonized' standards and are cited in the Official Journal of the European Union (OJEU).
The mandate requested the European Standardization Organizations (ESOs) to prepare a work programme of European Standards in order to support the MID.
In the joint response to the mandate, CEN identified work to be carried out by three Technical Committees (CEN/TC 92 'Water meters'; CEN/TC 176 'Heat meters'; CEN/TC 237 'Gas meters') and which consisted in the updating by amendment or revision of already adopted European Standards to conform the essential requirements of the directive.
The mandate invited CEN and CENELEC to develop standards for measuring instruments, as described in the joint response to the programming mandate M/347.
The mandate invites CEN and CENELEC to draw up standards for non-automatic weighing instruments (NAWI) in order to update the existing EN 45501, taking into consideration electromagnetic compatibility.
A CEN/CENELEC Joint Working Group (CEN/CENELEC JWG NAWI) has been set up to carry out the requested work.
Mr Ian Turner has been appointed as CEN consultant for measuring instruments.
