Legal Metrology

Legal metrology is the practice of applying regulatory structure and enforcement to the use of measurement instruments and measurement results.

Working Group 10: Measuring Equipment for Liquids Other Than Water

The aim of Working Group 10 is to consider and provide guidance on the Directive 2014/32/EC (MID) and the related normative documents or harmonised standards with regard to measuring systems for continuous and dynamic measurement of quantities of liquids other than water, to facilitate all aspects of implementation apart from inspection, enforcement and re-verification.

The Working Group's responsibility is also to consider and provide guidance on measuring instruments / systems falling outside of Directive 2014/32/EU, but treated by following OIML International Recommendations:

  • R81 (all parts) 'Dynamic measuring devices and systems for cryogenic liquids'
  • R80 (all parts) 'Road and rail tankers with level gauging'
  • R105 (all parts) 'Direct mass flow measuring systems for quantities of liquids'
  • R139 (all parts) 'Compressed gaseous fuel measuring systems for vehicles' and/or 'Compressed hydrogen fuel measuring systems for vehicles.

Representatives from WELMEC Members and Observer Organisations, OIML, European Commission and industry organisations participate in WG 10.
