Technical Information
Source container FQG61,
FQG62
Radiometric level measurement
Technical Information and Operating Instructions
Source container with source insert for manual or pneumatic switch-ON/switch-
OFF
Application
The FQG61 and FQG62 source containers are designed to hold the radioactive source
during radiometric point level measurement, continuous level measurement and
density measurement. The radiation is emitted almost unattenuated in one direction
only, and is damped in all other directions. FQG61 and FQG62 differ from each other
in terms of size and screening effect.
Your benefits
• Lightweight device provides best possible screening thanks to almost spherical
design
• Safe and easy source replacement
• Highest safety classification for the source supplied (DIN 25426/ISO 2919, typical
classification C66646)
• Compact device that is easy to mount
• Various angles of emission for optimum adaptation to the application
• Manual or pneumatic switch-ON/switch-OFF
• Padlock, cylinder lock or locking bolt for fixing the switch position
• Switch state easily identified
• Fire-resistant version +821 °C (+1510 °F) / 30 minutes

    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.

  • Page 9: General Instructions On Radiation Protection

    Distance Screening Ensure the best possible screening between the radiation source and yourself and all other persons. Source containers (e.g. FQG60, FQG61/FQG62, FQG63, FQG66) and all high-density materials (lead, iron, concrete etc.) can be used for effective screening purposes. Time The time spent in the exposed area should be kept to a minimum.

  • Page 10: Supplementary Safety Instructions

    The limit values for the control zone are specified in the current Radiation Protection Ordinance applicable for your area. The Endress+Hauser sales organization will be pleased to provide further information on radiation protection and regulations in other countries.

  • Page 11: Function And System Design

    Function Function of the radiation source container In the FQG61/FQG62 source container, the radioactive source is surrounded by a steel casing filled with lead which screens off gamma radiation. The radiation can be emitted, almost unattenuated, in one direction only through a channel (focused narrow beam path). This radiation is used for radiometric measurement.

  • Page 36: Orientation For Density Measurement

    Source container FQG61, FQG62 ‣ Orientation for density The most constant conditions for density measurement in pipes are achieved if the unit is mounted on vertical pipelines and the feed direction is from bottom to top. If only horizontal measurement pipes are accessible, the path of the beam should also be arranged horizontally to reduce the influence of air bubbles and buildup.
