- Abstract:
- A design for diverter valves in gravimetric liquid flow calibration facilities is examined. The concept makes use of repeated unidirectional motions of the diverter valve to reduce errors associated with asymmetry in the diverter valve motion and in the liquid jet velocity profile. Various implementation examples are provided and their benefits are discussed. The experimental results, given in a different paper, confirm the good performance of the error free diverter design. This new diverter design has been incorporated in the new NIST calibration facility.
