Calibration Services

Mass and Related Quantities: Volume Measurements

General

The Mass and related quantities Laboratory of SCL provide calibration services for various kind of volume vessels, such as measuring tanks, measuring cylinders, single channel and multiple channel pipettes and etc.

There are two methods employed by Mass and related quantities Laboratory for volumetric determination. The gravimetric method determines the mass of water either contained or delivered from a test measure. From the measured mass, the volume can be determined with a knowledge of water density and corrections for air buoyancy and thermal expansion of the vessel. The volumetric method requires a measurement standard (calibrated) volumetric measure. The volume of the test volumetric vessel is determined from the number of "dumps" of the measurement standard measure required to fill the test measure. Normally gravimetric method will be used for volumetric determination at the capacity of 20 L or below, whilst volumetric method will be used for measurements above 20 L.

To optimize the calibration results, the submitted vessels should be in a clean condition.
