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.

Arenal produces high accurate Analysers to control the quality of (demineralized) water. A submersible ceramic ultrasonic spectroscopy sensor is partly inserted in the water. The reference model is based on d.i. water, so changes in the acoustical physical properties of the liquid, due to salt, acid or organics are registrated immediately. The model is temperature depending, so the temperature is accurately measured as well.


Alternatively, when the contaminations are known and absorb in the UVVIS spectrum, our UV or UVVIS spectrometer may be more suitable as it can detect lower concentrations of the known contamination.


The same is applicable for monitoring Drinking Water Production and for Drinking Water Security programs. Every step in the production has certain physical and chemical properties that requires to be controlled within some boudaries. By continuous measurement with one of above probes, the quality of the drinking water is monitored continuously. In case of crossing a boundary limit, and alarm can be given and a sample can be taken.
