Nuclear (Radiation-Based)

Radiation-based sensors enable precise measurement of liquids and bulk solids under extreme process conditions such as high temperatures, pressures, and aggressive materials. They can be installed on the outside of process vessels during ongoing production, without disturbing the process in any way.

Featured Solutions

  • Pointrac-31

    The POINTRAC 31 is a radiation-based sensor for universal level detection of liquids and bulk solids. Independent of the mounting location, it monitors reliably the limit level in vessels. The sensor can be used for applications in all industries. Due to the high sensitivity POINTRAC 31 is an economical solution with minimum radiation activity.

    Application area

    The short rod detector monitors the limit level of liquids and bulk solids without contact. The sensor is used on vessels of any geometry and on pipelines.

    Your benefit

    • Exact measuring results independent of process conditions
    • High process reliability through determination of buildup
    • Economical level detection under arduous application conditions


    Fluid catalytic cracking unit

    Fluid Catalytic Cracking (FCC) is one of the most important conversion processes used in petroleum refineries. As with many other refining applications, the vessels in the reactor system need to be operated and controlled at their optimum levels, as this is critical for the process productivity. Maintaining the proper levels also ensures that the expensive catalyst is used at maximum efficiency, with no waste.


    In the digester, the action of chemical dissolution removes the lignin binder, thereby exposing and freeing the cellulose fibres. During the cooking process according to the alkaline sulphate method, the fibres are fed into the digester by means of steam pressure. To enable fully automatic operation of the digester, a point level detection of the filling is required. The vessel pressure also needs to be carefully monitored throughout this process.

    Continuous catalyst regeneration

    Platformers and reformers, both catalyst-based processes, require “fresh” catalyst at a given point in their cycle. To provide fresh catalyst without shutting down the process, a continuous catalyst regeneration unit can be installed. This unit regenerates the spent catalyst so that it can be used again. Maintaining the proper level in the vessel ensures that the expensive catalyst is used at the highest level of efficiency without waste.
