2 Basic safety instructions
2.1 Requirements for the personnel
The personnel for installation, commissioning, diagnostics and maintenance must fulfill
the following requirements:
‣Trained, qualified specialists must have a relevant qualification for this specific function
and task.
‣Are authorized by the plant owner/operator.
‣Are familiar with federal/national regulations.
‣Before starting work, read and understand the instructions in the manual and
supplementary documentation as well as the certificates (depending on the
application).
‣Follow instructions and comply with basic conditions.
The operating personnel must fulfill the following requirements:
‣Are instructed and authorized according to the requirements of the task by the facility's
owner-operator.
‣Follow the instructions in this manual.
2.2 Designated use
The Gammapilot M is a compact transmitter for non-contact level, point level, density and
concentration measurement. The measuring range of a single Gammapilot M is up to 2 m
(6.6 ft). Large measuring ranges of any size can be implemented, however, by cascading

4.2.2 Installation conditions for level measurement
Conditions
• For level measurements the Gammapilot M is mounted vertically; if possible the detector
head should point downwards
• The angle of emission of the source container must be exactly aligned to the measuring
range of the Gammapilot M. Observe the measuring range marks of the Gammapilot M.
• If several Gammapilot M devices are connected in cascade mode, there should not be any
gap between the individual measuring ranges.
• The source container and the Gammapilot M 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.

4.2.3 Installation conditions for point level detection
Conditions
• For point level detection, the Gammapilot M is generally mounted horizontally at the
height of the desired level limit.
• The angle of emission of the source container must be exactly aligned to the measuring
range of the Gammapilot M. Observe the measuring range marks of the Gammapilot M.
• The source container and the Gammapilot M 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 M should be protected against direct sunlight in order to increase its
service life. Use a protective cover if necessary.
• The mounting device FHG60 or an equivalent mounting device should be used to secure
the Gammapilot M →  86

4.2.4 Installation conditions for density and concentration
measurements
Density and concentration measurement
Conditions
• If possible, density and concentration should be measured on vertical pipes with forward
flow from bottom to top.
• If only horizontal pipes are accessible, the path of the beam should also be arranged
horizontally to minimize the influence of air bubbles and deposits.
• The Endress+Hauser clamping device FHG61 or an equivalent clamping device should be
used to fasten the radiation source container and the Gammapilot M to the measuring
tube. →  88
The clamping device itself must be installed in such a way as to withstand the weight of
the source container and the Gammapilot M under all anticipated operating conditions.
→  17
• The sample point may not be further than 20 m (66 ft) from the measuring point.
• The distance of the density measurement to pipe bends is ≥3 x pipe diameter, and ≥10 x
pipe diameter in the case of pumps.
Measuring system arrangement
The arrangement of the source container and the Gammapilot M depends on the pipe
diameter (or the length of the irradiated measuring path) and the density measuring
range. These two parameters determine the measuring effect (relative change in the pulse
rate). The measuring effect increases with the length of the radiation path through the
medium. Therefore, it is advisable to use diagonal irradiation or a measurement section for
small pipe diameters.
To select the measuring system arrangement please contact your Endress+Hauser sales
organization or use the Applicator™ 1)
1) configuration software. The Applicator™ is available from your Endress+Hauser sales organization.

• To increase the accuracy of 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
to prevent damage to the connecting cable.
• A clamping device (FHG61) and a measurement section (FHG62) are available as

Interface measurement
The measuring principle is based on the fact that the radioactive isotope (emitter) emits
radiation which is attenuated when it penetrates a material and the medium to be
measured. In radiometric interface measurement, the source is inserted into a closed
immersion pipe via a rope extension, thus preventing any contact between the source and
the medium.
Depending on the measuring range and the application, one or several detectors are
mounted on the outside of the vessel. The average density of the medium between the
radiation source and the detector is calculated from the radiation received. A direct
correlation to the interface can then be derived from this density value.

CP01205F/00/EN
Density profile measurement (DPS)
To obtain detailed information on the distribution of layers of different densities in a
vessel, a density profile is measured using a multi-detector solution. Several compact
transmitters are installed next to one another on the outside of the vessel wall for this
purpose. The measuring range is divided into zones and each compact transmitter
measures the density value in its respective zone. A density profile is derived from these
values.
This results in a high-resolution measurement of the distribution of medium layers (e.g. in
separators)
