4.2.9 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 or in an immersion tube in the vessel. 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 received is proportional to the concentration of the radiating medium in the
conveyed material.
4.2.10 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.
