Description
The system is used for the determination of free cross-sectional areas or diameter of drillings that are difficult to access and which can not be determined with geometric measurement methods. The measurement uncertainty of the system lies in the small μm range. Integrated within the system is a highly accurate pressure control for adjusting a pressure ratio across the test item. The calculation and analysis takes place via a developed software in LabVIEW.
