Abstract:
A Liquid microflow calibration rig was designed and evaluated. The developed calibration rig has a static weighing system and improved diverter valves for small flow rates. The weighing system succeeded in reducing an uncertainty due to an evaporation effect by using a detachable weighing tank. Experimental results of evaporation effect were introduced. In this study, two types of devices were introduced so that a Flying Start-and-Finish (FSF) method was implemented into the static weighing system. One of these devices is a set of diverting valves, and the other is a syringe pump with a linear encoder. Estimation tests were conducted. Diverter timing errors for the set of diverting valves were estimated to be about 6 ms.
