We consider a micropolar fluid flow with non-homogeneous boundary conditions. We prove that a certain type of singular behaviour of the velocity on any open subset of a space time domain can be detected by measurements of the normal part of velocity at the boundary. On the other hand, we show that the same type of singular behaviour of the velocity does not necessarily manifest itself in measurements of microrotation.
