FQG74, source container for radiometric level and density measurement that works reliably, is robust and easy to use, and can hold up to 20 radiation sources
Advantages
-
High safety (complies with Type A packaging requirements), high radiation protection rating
-
Easy commissioning of the radiation source; the source position inside the container can be adjusted individually via a separate cable (max. cable length 30 m)
-
Simplified safety measures, no controlled area required
-
Various container versions available to flexibly meet the requirements of different operating conditions
-
The switch position of the container can be securely locked with a padlock to prevent theft
Field of application
The FQG74 source container can hold up to 20 high-activity radiation sources during radiometric measurement. The container is robust, has a high radiation protection rating and can be easily installed on straight or angled tubes.
The FQG74 source container is used together with radiation detectors and is suitable for tasks such as limit detection, continuous level and density measurement. Suitable for large measuring range applications.
Oil and gas
-
Multi-point density measurement in the oil-water separation process
-
Level control of the catalyst bed in reactors during the hydrocracking process
Petrochemical/chemical
-
Level or multi-point density measurement of process reactors in PTA and urea production
