A Dedicated Source Container for Radiometric Measurement
The FQG60 is designed specifically to hold the radioactive source used in radiometric measurement systems. It can be used for point level detection, continuous level measurement and density measurement, providing the controlled source arrangement required for non-contact measurement through the process vessel.
Designed Around Radiation Safety
A major part of the FQG60's design is controlling the direction of radiation. Endress+Hauser states that radiation is emitted almost unattenuated in the intended direction while being damped in other directions. This design helps provide a high level of protection for personnel while maintaining the radiation path required for measurement.
Compact Construction for Industrial Installation
The FQG60 combines the shielding function and source mounting arrangement in a relatively small, lightweight container. Its compact construction makes it practical for installation around process vessels and measurement points where conventional contact instruments may not be suitable.
Suitable for Level and Density Applications
Radiometric measurement is particularly useful when the process itself makes conventional measurement difficult. The FQG60 can form part of systems used for level detection, continuous level measurement and density measurement, including applications where the measurement can be performed without direct contact with the process medium.
Manual Switching with Position Fixing
The FQG60 uses a manual switch-on/switch-off mechanism. The switching position can be fixed with a padlock or snap hook, while the switch-on status can be identified easily. This provides a straightforward physical arrangement for the source container within the overall radiometric measuring system.
Adaptable to Different Measurement Arrangements
The source container can be configured with different radiation emission angles to suit the measurement arrangement. An integrated mounting device is also available for density measurement on pipes, while an optional calibration plate can support density recalibration procedures carried out by qualified personnel.

Typical Applications
Radiometric Point Level Detection
The FQG60 can be used as the source container in radiometric point level detection systems where measurement is performed without direct contact with the process medium.
Continuous Level Measurement
For vessels where conventional level instruments are difficult to install or operate, radiometric measurement provides a non-contact measurement principle. The FQG60 houses and positions the radiation source used by the measuring system.
Density Measurement
The FQG60 can also be used in radiometric density measurement systems, including installations where the source is arranged around a process pipe.
Challenging Process Conditions
Radiometric measurement can be considered for processes where high temperatures, high pressures, corrosive media, or other process conditions make direct-contact measurement difficult. The FQG60 itself is installed externally and does not contact the process medium.
Industrial Process Measurement
The FQG60 is used as part of radiometric measurement systems across demanding process industries where reliable level or density information is required without introducing a conventional sensor into the process.
FAQ
What is the Endress+Hauser FQG60?
The FQG60 is a source container for radiometric measurement systems. It houses the radioactive source used for point level, continuous level or density measurement. It is not itself a level transmitter or density transmitter.
What radioactive source can be used with the FQG60?
Endress+Hauser specifies Cs-137 sources with activity up to 1.1 GBq (30 mCi) on the product page. The actual source and configuration depend on the complete radiometric measurement system and applicable regulatory requirements.
Can the FQG60 be used for density measurement?
Yes. The FQG60 is designed for radiometric density measurement as well as level measurement. Endress+Hauser also specifies an integrated mounting arrangement for density measurement on pipes.
Does the FQG60 contact the process medium?
No. The source container is installed externally and is classified by Endress+Hauser as non-contact with respect to the process. The radiometric measuring principle allows level or density measurement without placing the source container or detector directly into the process medium.
Is the FQG60 suitable for high-temperature or high-pressure processes?
The FQG60 product page lists no process temperature or process pressure limitation, because the source container is non-invasive and external to the process. The allowable conditions of the complete measurement installation still depend on the process vessel, mounting arrangement and selected radiometric system components.
How is the source position controlled?
The FQG60 uses a manual switch-on/switch-off mechanism. The switching position can be fixed mechanically, and the switch-on status is designed to be readily identifiable. Operation of radioactive-source equipment must follow the applicable safety procedures and regulations.
Can the FQG60 be used with different radiation directions?
Yes. Endress+Hauser specifies the possibility of different radiation emission angles so that the source container can be adapted to the measurement arrangement.
