| Zusammenfassung | The PTB Liquid Flow Group is developing a new primary measurement principle to determine liquid flow. Such a measurement principle is based on a dynamic-weighing approach, which is able to reproduce the unit of mass flow as a real measurand and not as a difference quotient of mass and time. The measurement concept relies on a mass-spring-damper model that simulates the mechanical response of the dynamic-weighing system (DWS) at different fluid flow conditions. The design and scope of a DWS prototype is also described in this document as well as the experiments that were made, to physically explain the system response. |
