Measuring systems for liquids other than water

Which different measuring systems are available?

Any system for measuring quantities of liquids requires legal approval, if it is intended for use in custody transfer.

  • 0.3

    Accuracy class 0.3

    Measuring systems of pipeline

  • 0.5

    Accuracy class 0.5

    All 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 (<20 mPa.s)
    • Measuring systems for (un)loading ships and rail and road tankers
    • Measuring systems for milk
    • Measuring systems for refuelling aircraft

  • 1.0

    Accuracy class 1.0

    Measuring 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 -10 °C or greater than 50 °C
    • Dynamic viscosity is higher than 1000 mPa.s
    • Maximum volumetric flowrate is not higher than 20 l/h

  • 1.5

    Accuracy class 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)

  • 2.5

    Accuracy class 2.5

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