APPLICATIONS

Mesens delivers accurate flow monitoring for abrasive and high-solid slurries using CIDRA’s patented passive SONAR, non-contact technology. SONAR is the only new flow measurement method developed since late 1970’s. This solution enables dual measurement of volumetric flow and gas void fraction (GVF = volume occupied by bubbles in the flow), even in the most challenging mineral processing conditions. Further it monitors in real time the flow model in the pipe allowing alarms on process disturbance situations, like flow segregation, so operators can immediately react to prevent line blockages.

It is ideal for cyclone feed lines, tailings, and other critical process pipelines where traditional sensors drift and fail due to wear or buildup. Measuring the propagation velocity of the turbulences that carry the solids forward, it is not affected by the properties of the flowing materials and provides better information on the flow of the actual product compared to e.g. magnetic flowmeters that basically measure the flow of carrier water and assume the material is evenly distributed in the line (with slurries this in practice never is the case).

Based on CiDRA CYCLONEtrac PST real time particle size measurement from every hydrocyclone overflow pipe we provide precise particle size controls to provide optimal particles to the following process stage (typically flotation or leaching). This leads to improvements in production throughput, recovery and creates savings in energy and water consumption. Additional advantages are the prevention of all off-grade particle size production and oversized particles entry to flotation cells.

For municipal and industrial water systems, the clamp-on SONAR technology ensures high-accuracy measurement without process interruption. Our systems offer true volumetric flow readings and GVF (=volume occupied by bubbles in the line) data for pipelines in both clean and harsh conditions—suitable for treatment plants, pumping stations, and distribution networks.

Installation requires no pipe cutting or service downtime, making it ideal for ongoing operations.
