Level Measurement in Desalters
Optimize Desalter Operations with Level Measurement Technology
Enhance Reliability and Environmental Safety in Desalter Processes
In desalter applications, maintaining reliability and environmental safety is paramount. The process involves removing salts and water from crude oil, which is crucial to preventing downstream equipment corrosion. Additionally, avoiding oil in wastewater systems is vital for environmental protection. Given the continuous nature of the process and the unsteady settling of liquids, monitoring water levels becomes critical.
With process characteristics involving hydrocarbons or water, high pressures, and temperature variations, the challenge of changing media properties persists. Rosemount™ level measurement solutions excel in these environments. Our instruments ensure efficient and accurate performance by managing density changes, detecting build-up, and providing precise interface measurements. This leads to enhanced process efficiency, safety, and overall optimization in desalter operations.

Product Solutions
The Magtech MLT Level Transmitter may be utilized as a direct insertion transmitter for in-pipe measurement or externally mounted to a magnetic level indicator for non-invasive level measurement. The magnetostrictive level transmitter senses the level of fluid in the vessel by detecting the level of the magnets contained within the float and transmits the measurement back to the control system. The Magtech MLT works in combination with the Magtech Magnetic Level Indicator to provide an ideal solution for high-pressure, high-temperature applications.
- User-friendly setup via self-promting menus
