Measuring instruments directive 2014/32/EU 

Directive 2014/32/EU of the European Parliament and of the Council of 26 February 2014 on the harmonisation of the laws of the member of states relating to the making available on the market of measuring instruments.

Accuracy ClassType of Measuring system
0,3Measuring systems of pipeline
0,5All measuring systems if not differently stated elsewhere in this table, in particular:

  • Fuel dispensers (not for liquefied gases)
  • Measuring systems on road tankers for liquids of low viscosity (<29 mPa.s)
  • Measuring systems for (un)loading ships and rail and road tankers
  • Measuring systems for milk
  • Measuring systems for refuelling aircraft

1,0Measuring systems for liquefied gases under pressure measured at a temperature equal to or above -10°C
Measuring systems normally in class 0,3 or 0,5 but used for liquids

  • Whose temperature is less than -10C or greater than 50°C
  • Whose dynamic viscosity is higher than 1000 mPa.s
  • Whose maximum volumetric flowrate is not higher than 20 L/h

1,5

  • Measuring systems for liquefied carbon dioxide
  • Measuring systems for liquefied gases under pressure measured at a temperature below -10°C (other than cryogenic liquids)

2,5Measuring systems for cryogenic liquids (temperature below – 153 °C)
