SDM ECO / SLURRY DENSITY METER
Slurry density.
Without nuclear.
Measure mineral slurry density in real time with non-intrusive ultrasonic technology. Built for abrasive process conditions, high-density slurries and large pipes.
Ultrasonic measurement, without a radioactive source.
Continuous density insight for process control.
A sensor designed for demanding mineral slurries.
Options for large and partially filled pipes.
THE SYSTEM
Reliable measurements.
Practical control.
The SDM ECO combines an ultrasonic sensor, transmitter and operator interface to provide accurate, reliable slurry density measurements for continuous process optimisation.
Use density data to understand changes in your slurry, support process decisions and replace nuclear measurement with a non-nuclear alternative.
SDM ECO system views. Use the arrows or swipe to explore the operator interface, transmitter and pipe integration.
Upgrading from SDM-4?
SDM ECO brings improvements to accuracy, response time, operating temperature range and sensor design.
INDUSTRIES & APPLICATIONS
Where density makes a difference.
Explore how ultrasonic density measurement supports the processes that matter to your operation.
Traitement des minéraux
Monitor mineral slurry density across grinding, flotation and thickening circuits.
Dragage
Measure dredging slurry inline and support production monitoring without a radioactive source.
Tunnels
Monitor slurry solids concentration to support bentonite recovery in tunneling operations.
PIPE INTEGRATION
A practical fit for your process.
Select the installation arrangement around your pipework, slurry and operating conditions. The SDM ECO is designed for straightforward installation, operation and maintenance.
INSTALLATION & SUPPORT
Plan the right installation.

SOUTH AFRICA / FIELD COMPARISON
Thickener underflow.
A non-nuclear alternative.
At a chrome and PGM processing site, trial data showed comparable accuracy to the installed nucleonic meter, with a faster response to density changes.
Results from this installation; performance depends on the application and configuration.
