Mass Flow Orientation
For continuous mass flow determination, you must mount the source holder
above a conveyor belt or a discharge screw conveyor. Make certain the radiation is
directed exactly towards the detector mounted on the opposite side.
Mount the source holder SHLD 2 on the measuring frame (optional). There are
large spacings and gaps between the measuring frame and conveyor belt.
If there are gaps or empty spaces around the installation, provide protective
fences or grids to keep hands away from the dangerous area. You must mark
such areas accordingly.
The arrangement of the source holders depends on the width and the loading
height of the conveyor belt. In the case of wide conveyor belts, using two sources
holders is advantageous.
Make sure that the total width of the conveyor belt as well as the complete loading
height are in the detection range of the measuring system.

Make sure when planning the measuring system that the sensor electronics are
easily accessible. Mount the sensor in such a way that the sensor housing is on
the same side as the catwalk. Mount the source holder with symmetrical radiation
orientation (60°) so that the manual switchover mechanism is also accessible from
the catwalk side
