Radiometric level and density instruments to optimise production at oil refineries and petrochemical plants with increased safety and reliability

Dec 04 2023

Berthold Technologies’ radiometric instruments for non-invasive level and density measurement are widely used in the oil refining and the petrochemical industry worldwide.

Berthold’s measurement solutions, utilising gamma absorption, help their customers in achieving highly reliable process control. This ensures safe operations, maximises efficiency, and ultimately boosts profitability. Berthold is known for cutting-edge technology and high-quality products; they offer an extensive array of industry-standard solutions, while also collaborating closely with customers and licensors to design customised systems specifically tailored to their unique processes and measuring requirements.

LB 476 Level+ adds that little extra to radiometric level measurements, which makes it the perfect system for the most challenging processes such as level measurement in delayed coke drums. Compared to the classic radiometric level measurement, LB 476 Level+ enables the storage of two calibration curves and, beyond, the simultaneous monitoring of two product levels based on those calibration curves. Moreover, by using the outstanding implemented compensation functions, level measurement falsifications, e. g. due to gas density fluctuations or due to product build-ups, belong to the past. LB 476 Level+ can be used with both LB 4700 DuoSeries detectors or LB 480 SENSseries detectors.

The LB 476 Level dual level measurement technology makes it ideal for measurements of products in processes with two significantly different process stages (e. g. normal and outage stage in the delayed coking process). The device includes outstanding compensation functions to prevent measurement falsification using Gas Property Compensation (GPC) and Product Buildup Compensation (PBC). The LB 4700 DuoSeries detectors (only two wires) or LB 480 SENSseries detectors (316L housing as option and own current output) can be used as detector options. The LB476 offers single level and total level output in cascaded systems, therefore operators can monitor output of the total level value as well as the individual levels of the respective level detectors.
