Calibration of static liquid volume standards

Static liquid volume standards and hydrometers used by Measurement Canada inspectors and authorized service providers are calibrated for use in the field.

Only standards used by Measurement Canada inspectors and authorized service providers are calibrated by Measurement Canada's laboratories. Standards and apparatus must be authorized and registered with Measurement Canada to qualify for this service.


Method

Gravimetric calibration of "to deliver" liquid volume of:

  • Graduated glass cylinders: 10 mL to 2000 mL
  • Level 1 open neck provers and test measures: 1 L to 40 L with sight glass or slicker plate design
  • Level 1 open neck provers: 40 L to 500 L with sight glass design and bottom drain assembly

Gravimetric calibration of "to contain" liquid volume of:

  • Steel stoppered pycnometers: 100 mL to 1000 mL

Volumetric calibration of "to deliver" liquid volume of:

  • Level 2 and 3 open neck provers: 20 L to 2500 L

Hydrostatic weighing of:

  • Pressure hydrometers (0.470 to 0.510 × 0.0005 g/cm³ or 0.500 to 0.550 × 0.0005 g/cm³, stem diameter up to 17 mm, length up to 370 mm) is performed by the National Research Council (NRC) and corrections for liquefied propane gas are performed by Measurement Canada

Calibration location

  • Level 2 and level 3 volume standards are calibrated by Measurement Canada regional offices.
  • All other devices are calibrated by Measurement Canada's Approval and Calibration Services Laboratory (ACSL) in Ottawa, Ontario.
    • Pressure hydrometers measurements are performed by the NRC and corrections are performed by Measurement Canada's ACSL. These devices must first be submitted to the ACSL.
