The detector should be mounted in a horizontal pipeline at the top or side. This will
prevent that the measurement is influenced by any deposits on the ground of the
pipeline.
4.5 Measurement on a Conveyor Belt
Normally, the required saturation thickness cannot be reached on a conveyor belt, so the
measured result will be influenced by changes of the bulk weight and/or changes of the
material layer thickness.
However, if it is ensured that
• variations of the bulk weight in the material cannot occur (uniform grain size)
• the height of the material layer is kept constant by leveling device.
a measurement can also be carried out on a conveyor belt. However, the measurement
error is larger than with measurements in a bunker.
