Level Measurement for Chemical Storage Process Vessels
Improve safety and level measurement accuracy in chemical storage tanks
Accurate, Reliable and Safe Level Monitoring and Control
Chemical storage tanks are used in many different applications in the chemical process industry. From storage of raw materials in small and large containers and tanks, to intermediates and storage of final products. Some of the challenges that storing various types of chemicals can present are presence of corrosive media, condensation, foam and risk of media build-up if contents are viscous or sticky.
Safe storage of chemicals is essential for plant safety to prevent unwanted overfill and risk of overspill. Reliable level measurement technology is the key to having high level of quality control and reliable overfill prevention or underfill / run-dry prevention.
Emerson's new non-contacting radar portfolio together with its point level detection portfolio provide ideal solutions to meet the diverse needs of chemical storage tanks in the industry.

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
