Safety instructions
Designated use
The FQG61 and FQG62 source containers described in this document contain the radioactive source,
which is used for radiometric measurement of level, interface and density. They screen the radiation
from the surrounding environment and allow it to be emitted almost unattenuated in the direction of
measurement only. In order to guarantee the screening effect and rule out damage to the radiation
source, it is essential to comply strictly with all the instructions provided in this Technical
Information document for mounting and operating the unit, as well as all legal regulations
surrounding radiation protection. Hauser does not accept any responsibility for damage
caused by incorrect use.
Basic instructions for use and
storage
• Observe the applicable regulations and national/international standards.
• Comply with radiation protection regulations when using, storing and working with the
radiometric measuring system.
• Heed warning signs and observe safety zones.
• Install and operate the device according to the instructions in this document and as specified by
the regulatory authority.
• Never operate or store the device outside the specified parameters.
• When operating and storing the device, protect it against extreme influences (i.e. chemical
products, weather, mechanical impacts, vibrations etc.).
• Always secure the OFF position of the source insert using the padlock
• Before switching on the radiation, make sure that no-one is in the radiation zone (or inside the
product vessel). The radiation may only be switched ON by properly instructed staff.
• Do not operate damaged or corroded devices. Notify the competent radiation safety officer as soon
as damage or corrosion occurs, and follow his/her instructions.
• Conduct the required leak testing procedure according to the applicable regulations and
instructions

WARNING
Vibrations and mechanical impacts
‣
If the device is exposed to strong vibrations or mechanical impacts, the safety pin can become
abraded. This may cause the source insert to fall out of the container.
‣
Therefore, the source holder must be checked at regular intervals to ensure that it is secure and
stable
L
CAUTION
Condition of the system
‣
If there are any doubts about the proper condition of the system, check the area around the
device for leakage radiation and notify the competent radiation safety officer.
Hazardous areas
General instructions
L
CAUTION
Suitability
‣
The suitability of the radiometric measurement method and of the device for applications in
hazardous areas must be checked by the plant operator according to the national rules and
regulations that apply.
The following must be observed:
• Avoid electrostatic charge at the device. Do not rub dry.
• The device must be integrated in the potential equalization system of the plant. In order to ensure
electrical contact between the radiation source container and the mounting support, the supplied
toothed lock washers must be used.→ 37
If an RFID tag is used, comply with the instructions in the
SD01502F/00 document, which is supplied separately
