We provide calibration services for liquid flow meters using seven calibration facilities as national standards. The calibration facilities for water flow cover the range between 2 L/h and 12 000 m3/h with uncertainties between 0.039 % and 0.081 %. The calibration facilities for oil flow cover the range between 0.02 L/h and 300 m3/h with uncertainties between 0.020 % and 0.078 %.
