Comparison Test between the Light Oil Flow Standard System and Calibration System by Using the Turbine Flowmeter Package

摘要

In order to scrutinize the reliability of Light Oil Flow Standard System (LOFSS) measurements, a round robin test was carried out with the three calibrators. The tested calibrators had different principles and working fluids. A turbine flowmeter package was used as the transfer standard (TS), which had a tube bundle-type flow straightener and 22- and 5-pipe (in diameter) long straight pipe up and down stream, respectively. The TS was tested in a range of 20 and 240 m~3 /h (Reynolds No. 2×10~4 and 9×10~5. Due to the different physical properties of the fluid, the test results were compared based on the Reynolds numbers.
