Level Measurement in Production and Sizing Bins for Potash Production
Accurately and responsively measure potash material levels to ensure adequate supply in fast-moving operations.
Continuous Level Monitoring with Non-Contacting Radar Technology
As potash material proceeds through the cleaning and grinding process, it is collected in production bins at various points. In the sizing process, material that is over- or undersized is recirculated for additional processing. Oversized material may be reground, while undersized material may be sent to the compaction area to become granular potash. Very fine powder is sent to the crystallization area to be made into a liquid or a finer powdered fertilizer. In production and sizing bins, the level may change quickly as the silos empty and refill, making a responsive level measurement critical to determine adequate supplies for production. In addition, the material is very dusty, making measurements difficult.

Product Solutions
The Rosemount™ 5408 Non-Contacting Radar Level Transmitter uses enhanced technology and Human Centered Design to deliver accurate, reliable measurements on both liquid and solid materials. Using two-wire FMCW and Smart Echo Supervision technologies, the Rosemount 5408 deploys a continuous echo to maximize radar signal strength and produce a more robust and reliable measurement. Delivering ease-of-use at every touch point, the Rosemount 5408 uses an intuitive software interface to guide the operator through installation, commissioning, proof-testing and maintenance. Powerful onboard diagnostics suite proactively monitors transmitter health and alerts if there is an issue. Safety certified to IEC 61508 for SIL 2 applications, the Rosemount 5408:SIS reduces cost of risk, increases efficiency and protects people and the environment.
- With Smart Echo Supervision™ technology, Rosemount Non-Contacting Radars automatically track all echoes, including those from obstructions in the vessel, and distinguish them from the real product surface echo. This ensures the true product level is reliably and accurately reported.
