Description

The FQG63 source container is designed to hold the radioactive source during radiometric level, density and interface measurement. The radiation is damped in all directions as long as the source container is switched off. This guarantees highest safety for the personnel and a reliable measurement. If the source is switched on and lowered down into the process tank, it emits the radiation into all directions.

Field of application

Designed to hold the radioactive source during density and interface measurement.

  • Off-position: Radioactive source located in the source container and screens off radiation
  • On-position: Radioactive source with the flexible extension located in the protection pipe inside the process vessel
  • Activity: 137Cs to 185.0GBq (5000mCi), 60Co to 3.7GBq (100mCi)
  • Temperature: -52 to +400°C (-62 to +752°F)
  • Pressure: No limitation (non-invasive, extraneous)
Benefits
  • Highest safety classification for the source supplied (DIN 25426/ISO 2919, typical classification C66646)
  • Reliable measurement due to lightweight container and almost spherical design which provides optimized screening
  • Flexible installation length up to 30m (98ft)
  • Manually operated and padlock, cylinder lock or locking bolt for fixing the switching position
