2.2.4 Installation conditions for density and concentration measurement
Conditions
• If possible, density and concentration should be measured at vertical pipes with a feed direc-
tion from bottom to top.
• If only horizontal pipes are accessible, the path of the ray should also be arranged horizontally
to reduce the influence of air bubbles and sediments..
• The Endress+Hauser clamping device (see BA00236F/00/EN, Chapter "Accessories") or an
equivalent clamping device should be used for fastening the radiation source container and
the Gammapilot M to the measuring tube. The clamping device itself must be installed in a
way such that it can withstand the weight of the source container2) and the Gammapilot M 3)
under all operating conditions.
• The sample point may not be further than 20 m from the measuring point.
• The distance of the density measurement to
– pipe bends is ≥ 3x 3 x pipe diameter
– pumps≥10x pipe diameter
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 measuring
effect increases with the length of the radiation path through the medium. Therefore, diagonal
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..

Before wiring, connect the potential matching
line to the external ground terminal of the trans-
mitter. If a water cooling jacket is present, it must
be separately connected to the potential matching
line.
"Caution!
In Ex applications, the instrument must only be
grounded on the sensor side.
Further safety instructions are given in the separate
documentation for applications in explosion
hazardous areas.
!Note!
For optimum electromagnetic compatibility the
potential matching line should be as short as
possible and at least 2,5 mm2in cross-section.
