You can mount the FIBERTRAC 31 with the housing head upward or

downward. When the housing head is mounted downward, the hous-

ing itself is more easily accessible.

Fasten the sensor in such a way that it cannot fall out of the holder. If

necessary, provide the sensor with a support from below.

Direct the exit angle of the source container to the FIBERTRAC 31.
