Level Measurement Solutions for Blending and Mixing Tanks
Continuous and point level measurement and control solutions for the chemical industry
Robust, Reliable and Accurate Level Measurement
Blending or mixing tanks are used in many processes in the chemical industry for combining different fluids, or combining fluids with solid media. Mixing vessels may be at ambient or elevated temperatures to enhance dissolving. Level measurement technology is needed to monitor and control addition of media and prevent overfill/ overspill from the vessel. Common challenges include the presence of corrosive media, condensation, foam and risk of media build-up if contents are viscous or sticky. Usually, the blending or mixing tank is equipped with an agitator, so non-contacting and/or low-intrusion instrumentation is desirable so as to not interfere with internal obstructions.
Emerson's Rosemount non-contacting radar level transmitter portfolio combined with the Rosemount 2100 Level Switch series provide ideal level measurement solutions that can withstand harsh and changing conditions.

Product Solutions
The Rosemount 3408 Non-Contacting Radar Level Transmitter is a versatile FMCW radar, which features Smart Echo Supervision™ technology, and is suitable for level measurement and overfill prevention in many industries, including chemical. Smart features save time and maximize efficiency for trouble-free operations, simplifying commissioning, operation and testing. Smart diagnostics help you proactively plan maintenance and optional Bluetooth® connectivity allows convenient configuration and maintenance. Manual or automatic verification at scheduled intervals can be conducted from the control room at any time without process interruptions. Perform proof-testing remotely and in-situ with onboard functionality. NAMUR type tested and third party certified to IEC61508 for use in safety critical applications.
- 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.
- 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
