- Abstract:
- For the design and construction of an standard volumetric installation for water flowmeters verification/calibration, is taken account of all the metrological, structural and functional characteristics requirements and the measurement uncertainty.All the individual uncertainty components of the volumetric installation for water meters verification should have predefined values and provide for the total expanded measurement uncertainty of the installation a smaller value. For calibration of volumetric installations, standard volume measures are required for secondary calibrations with appropriate nominal values, pipette, thermometer, chronometer.Measurement uncertainty evaluation involves determining the influence factors of the calibration. The main factors of influence are: volume measurement of the installation; the volume correction due to the temperature of the liquid; correction due to liquid evaporation; correction due to leakage.
