dc.description.abstract | Installation for precise flow meter calibrations meets demands
of the relevant standards: high-quality installation, appropriate calibration
methodology, instruments of high accuracy and satisfactory measurement
uncertainty. So, it is necessary to calibrate the flow meter on an adequate
installation. Designed and assembled installation for flow meters
calibration for measurement of liquid flow in closed conduits up to 10
l/min, based on weighing method, is presented in this paper. Modified
measurement methodology, which mainly follows standard ISO 4185, is
presented in this paper. The geometry of the whole installation is presented
and afterwards used for numerical experiments. Two numerical meshes
were tested. First approach had a half a million cells and the second mesh
was consisted of approximately 1.6 million cells. Both meshes were
unstructured. Numerical results were used for installation test before
manufacturing and assembling. The test rig was manufactured after the
numerical results evaluation. Experimental validation of the calibration
procedure followed. Obtained experimental results and measurement
uncertainty for three operating regimes were analysed and reported. It was
proved, experimentally and numerically, that uniform, i.e. developed
turbulent flow, was achieved in the straight measurement section, what is
of great importance for flow measurement calibration. | sr |
