Abstract

Calibration of volumetric proving tanks can be done using different methods. For thecalibration of large proving tanks the master meter method can be used as a goodalternative to the volumetric transfer method or the gravimetric method. When the mastermeter method is used in most cases a positive displacement meter is used. A better optionis to make use a Coriolis mass flow meter as the master meter. Test data is presented of acalibration of a proving tank with a nominal volume of 500 L. Small repeatability figurescan be obtained of consecutive calibration runs with a Coriolis mass flow meter. Also thelinearity of the meter factor curve of the Coriolis mass flow meter makes this a betteroption for the master meter method.
