Abstract
Ultrasound Doppler pulse velocimetry for the measurement of bubble velocities and local temperature pulse time-of-flow techniques for determining the flow velocities of the liquid phase are two complementary new measuring techniques to gain information on the fluid dynamic behavior of bioreactors. Both methods show considerable advantages over conventional techniques. They proved to provide reliable results during biotechnological cultivations. Results from runs in airlift loop bioreactors are reported.
