Primary standard and traceability chain for microflow of liquids
Original language description
To enlarge calibration capacity of existing liquid flow test bench in CMI - Czech Republic to lower flows a new primary test bench using gravimetric method at atmospheric conditions is being established. The range of flow is (0,001 ? 100) mL/min. With accuracy increasing of offered flow meters, of course, requirements to reduce the uncertainty of the primary or secondary standard has been rising. Detailed design of the CMI primary standard equipment and experience with used measuring methods are subjectof the article. The main focus of the paper are gap analysis for different dynamic testing methods (weighing, volumetric with piston) as well as detailed uncertainty analysis. Also a traceability chain to the end users´ flow meters is presented.
