    In this study a novel laboratory-scale pipe rheometer is utilized in Theological characterization of concentrated MFC and cellulose suspensions. The method is based on a combination of pulsed ultrasound velocity profiling (UVP) and pressure difference measurement (PD). The Theological properties of the suspensions are described in terms of pressure loss, viscosity and yield stress. The results are compared to rotational rheometer results. It is demonstrated that a well controlled pipe flow environment together with the UVP-PD technique is efficient in characterizing the rheological flow behavior of complex slurries
