Gammapilot M. Observe the measuring range marks of the Gammapilot M.
• The source container and the Gammapilot M must be mounted as close to the vessel as pos-
sible. Any access to the beam must be blocked so that no persons or part of their body (hand,
arm, head) may come into the area of the beam.
• In order to enlarge the lifetime, the Gammapilot M should be protected against direct sun.
If necessary, a protective cover should be applied.
• The mounting device FHG60 (see BA00330F/00/EN, Chapter "Accessories") or an equivalent
mounting device should be used for fastening the Gammapilot M.

Configuration of the measuring system
The configuration of the source container and the Gammapilot M depends on the pipe diameter
(or the length of the irradiated measuring path respectively) and the measuring range. These
two parameters determine the measuring effect (relative change of the pulse rate). The measu-
ring effect increases with the length of the radiation path through the medium. Therefore, dia-
gonal irradiation or the use of a measurement section is necessary for small pipe diameters.
For the configuration of the measuring system please contact your Endress+Hauser sales orga-
nization or use the "Applicator" 4) configuration software..

NOTICE
General
‣To increase the accuracy for density measurements, the use of a collimator is recommended.
The collimator screens the detector against environmental radiation.
‣When planning, the total weight of the measuring system must be taken into consideration.
‣The Gammapilot M should be given additional support to secure it against falling or prevent
damage to the connecting cable.
‣A clamping device and a measurement section are available as accessories (see
BA00330F/00/EN, chapter "Accessories").
