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.

• When planning, the total weight of the measuring system must be taken into
consideration.
• The Gammapilot FMG50 can be given additional support (retaining bracket) to secure
it against falling or to prevent damage to the connecting cable.
• A clamping device is available as an accessory
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
