Although the ceramic ultrasonic and thermal sensors of Arenal PCS can be applied in any liquid in the world, it is mainly designed for abrasive slurries and pastes, which can be found in Mineral and Metal processing plants, dredging and tunneling. Arenal is actively involved in industrial slurries, like in CMP, pigment and catalysts slurries and battery pastes and potato starch slurries.

The optimal slurry for measuring density, flow and massflow is a homogene turbulent slurry in a pipe or vessel, with a large concentration of particles below 1 mm.
