2.3 Installation, commissioning and operation
The Gammapilot FMG50 is designed to meet state-of-the-art safety requirements and
complies with applicable standards and EU regulations. However, if it is used improperly or for
applications for which it is not intended, application-related hazards may arise, e.g. product
overflow due to incorrect installation or configuration. Installation, electrical connection,
commissioning, operation and maintenance of the measuring system must therefore be
carried out exclusively by trained specialists authorized to perform such work by the system
operator. Technical personnel must have read and understood these Operating Instructions

3.2.5 Installation conditions for density measurement
Conditions
• If possible, density 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 or an equivalent clamping device should be used to
fasten the source container and the Gammapilot FMG50 to the measuring pipe.
The clamping device itself must be installed in such a way as to withstand the weight of the
source container and the Gammapilot FMG50 under all anticipated operating conditions.
• 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 FMG50 depends on the pipe
diameter (or the radiated length) and the density measuring range. These two parameters
determine the measuring effect (relative change in the pulse rate). The longer the radiated
length, the greater the measuring effect. 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.

• When the Gammapilot FMG50 is installed upside-down, it can be given additional
support (retaining bracket) to prevent damage to the connecting cable or to the unit if
it falls.
3.2.6 Installation conditions for interface measurement
Conditions
For interface measurement, the Gammapilot FMG50 is typically mounted horizontally at the
upper or lower limit of the interface range. When introducing a radiation source into an
immersion tube, it is important to ensure that the measuring range is already filled with
medium in order to keep the radiation in the vicinity of the source as low as possible. When a
radiation source is used in an immersion tube, the radiation can only be aligned with the
measuring range of the Gammapilot FMG50 using a collimator on the immersion tube.
Description
The measuring principle is based on the fact that the radiation source emits radiation which is
attenuated when it penetrates a material and the medium to be measured. In radiometric
interface measurement, the radiation source is often introduced into a closed, double-wall
immersion tube via a cable extension. This excludes the possibility of contact between the
radiation 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 position
of the interface can then be derived from this density value.

CP01205F/00/EN
3.2.7 Installation conditions for density profile measurement (DPS)
Conditions
For density profile measurement, Gammapilot FMG50 devices are installed horizontally at
defined distances, depending on the size of the measuring range. In the case of density profile
measurement, the radiation source is normally inserted in an immersion tube, preferably one
that is double-walled, and introduced into the vessel. When introducing a radiation source
into an immersion tube, it is important to ensure that the measuring range is already filled
with medium in order to keep the radiation in the vicinity of the source as low as possible.
Description
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 FMG50 devices 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)
For more information, see:
CP01205F/00/EN
3.2.8 Installation conditions for concentration measurement
Conditions
• If possible, the 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 or an equivalent clamping device should be used to
fasten the source container and the Gammapilot FMG50 to the measuring pipe.
The clamping device itself must be installed in such a way as to withstand the weight of the
source container and the Gammapilot FMG50 under all anticipated operating conditions.
• When the Gammapilot FMG50 is installed upside-down, it can be given additional support
(retaining bracket) to prevent damage to the connecting cable or to the unit if it falls.
• 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.

The arrangement of the source container and the Gammapilot FMG50 depends on the pipe
diameter (or the radiated length) and the density measuring range. These two parameters

3.2.9 Installation conditions for concentration measurement with radiating media
Measurement of the concentration of radiating media in vessels
The concentration of radiating media in vessels can be determined by taking a measurement
at the vessel wall. The intensity of the radiation received is proportional to the concentration
of the radiating medium in the vessel. It is important to note that the medium in the vessel
also absorbs its own radiation. The detected radiation will not increase further with larger
diameters and the signal is saturated. This saturation length depends on the half-value layer
of the material.
The level in the vessel must be constant in the vicinity of the detector to ensure the
measurement is correct.
Measurement of the mass flow of radiating media
In the case of belt scales and pipes, the concentration of the radiating medium can be
measured in the sample. Here, the device is mounted above or below the conveyor belt so that
it is parallel to the belt direction, or is mounted on the pipe. The intensity of the radiation

Gammapilot M FMG50 Mounting
Endress+Hauser 19
received is proportional to the concentration of the radiating medium in the conveyed
material.
3.2.10 Installation conditions for flow measurement
Measurement of mass flow (liquids)
The density signal determined by the Gammapilot FMG50 is transmitted to the Promag 55S.
The Promag 55S measures the volume flow; the Promag can determine a mass flow in
connection with the calculated density value.

Bulk solids applications on conveyor belts and conveyor screws.
The source container is positioned above the conveyor belt and the Gammapilot FMG50 below
the conveyor belt. The radiation is attenuated by the medium on the conveyor belt. The
intensity of the radiation received is proportional to the density of the medium. The mass flow
is calculated from the belt speed and the radiation intensity.
