Acceleration measurement for flow tracking in bioreactors with sensor particles

The triaxial measurement of accelerations using sensor particles in bioreactors is essential for flow analysis. Due to the mechanical structure of the sensor particles, the accelerometer is not located in the center of the applied forces. Therefore, centrifugal and Euler acceleration superpose its measurements. Due to the high dynamics and the high angular velocities that the sensor particle experiences in the reactor, this influence cannot be neglected despite the small size of the sensor particles and must be taken into account in the system model.
