Level Measurement of Sump Pits in the Oil and Gas Industry
Achieve reliable level and interface measurement with top down technology.
Prevent Overfilling, Harmful Overspills, and Damage to the Environment
A sump is a vessel located in a low place or below key equipment that collects waste or overflow liquids like waste oil, condensate, chemicals, or water which are collected for reprocessing or disposal. Treated wastewater or rain collection water is stored in open atmosphere sumps. Sumps are also used to collect waste product streams. They are often placed underground for ease of filling and for insulation when situated in locations with extreme climates. The sump is often accessible with only top-down measurement technology. It is sometimes desirable to also measure interface, in which case guided wave radar technology such as the Rosemount 5300 Level Transmitter is the recommended solution. For remote locations with no cable infrastructure, a wireless guided wave radar such as the Rosemount™ 3308 Level Transmitter enables efficient and accurate level control and data collection. If a non-contacting solution is preferred, the Rosemount 3408™ Level Transmitter is an alternative choice.

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
