Installation conditions for
point level detection
Endress+Hauser

Installation conditions

• The angle of emission of the source container must be exactly aligned to the measuring range of
the Gammapilot FMG50. Observe the measuring range marks of the device.
• The source container and the Gammapilot FMG50 should be mounted as close to the vessel as
possible. Any access to the beam must be blocked to ensure that it is not possible to reach into this
area.
• The Gammapilot FMG50 should be protected against direct sunlight or process heat in order to
increase its service life.
• Feature 620, option PA: "Weather protection cover 316L"
• Feature 620, option PV: "Heat shield 1200-3000 mm, PVT"
• Feature 620, option PW: "Heat shield NaI, 200-800 mm, PVT"
• Terminals can optionally be ordered with the device
• The mounting device must be installed in such a way as to withstand the weight of the
Gammapilot FMG50 under all anticipated operating conditions (e.g. vibrations).
More information with regard to the safety-related use of the Gammapilot FMG50 can be
found in the Functional Safety Manual.
Conditions
• The Gammapilot FMG50 is mounted vertically for level measurements.
• To facilitate installation and commissioning, the Gammapilot FMG50 can be configured and
ordered with an additional support (order feature 620, option Q4: "Retaining bracket").
