Level Measurement in Cement Silos
With Radar Level Measurement
Optimize Inventory Management and Personnel Safety
During concrete production, cement is stored in large silos before entering the mixing process. The process creates a very dusty environment inside the silo. Build-up and rat holes tend to occur, risking damage to the silo. Knowing the quantity of material is important to ensure continuous production process.

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.

The Rosemount 3408 Non-Contacting Radar Level Transmitter, with Smart Echo Supervision™ technology, offers enhanced reliability for level measurement and overfill prevention.
- It supports wireless and remote configuration through optional Bluetooth® for the wired model or WirelessHART® for automated measurements in hard-to-reach areas, cutting down wiring costs.
- The transmitter's smart diagnostics package provides real-time monitoring, remote testing, health checks, and historical data access, enhancing safety, efficiency, and proactive maintenance.
- Safety certifications, including SIL2 (IEC61508) and NAMUR type testing, along with remote proof-testing, ensure protection for people, assets, and the environment.
- With Smart Echo Supervision™ technology, Rosemount Non-Contacting Radars (except for wireless models) 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.
- Lens antenna available for very small process fittings (3/4") and with optional bracket mount
- All PTFE wetted parts allow for use in harsh conditions, such as corrosive medias
