  Ultrasonic  velocimetry  using integrated  time  of flight  F. Burmann*  and J. Noir ETH Zurich   Most common techniques in flow diagnostics rely on the presence reflectors  in the fluid, either for light or acoustic waves. These methods fail to operate when e.g centrifugal or gravitational acceleration  becomes significant, leading to a rarefaction of scatters in the fluid, as for instance in rapidly rotating fluids.  Such conditions will  occur in the upcoming liquid sodium experiment  SpiNaCH, currently under construction at ETH Zurich.  In this study we present  a novel technique based on the time of flight principle to perform velocity measurements in the absence of scattering particles.
