Method and apparatus for determining a volume flow

摘要

In a process for the determine ton of a volume flow a fluid is passed through a measuring line with a defined cross-section. In the measuring line the flow rate and the fill degree of the measuring line are determined and the volume flow is determined from the flow rate, the measuring line cross-section and fill degree. The determination of the flow rate and the fill degree takes place with a single measuring chamber at the same time and at the same location with respect to the axial extension of the measuring line.
