Withdensitymeasurement,theradiationdierencewithdiering
density is very low. Especially with small tube diameters, the change
is negligible.
Therefore it is important to shield from interfering X-ray radiation. To
protect the instrument against X-ray radiation, it can be be equipped
withanoptionalleadring.Alaterretrottingoftheleadringisnot
possible.
Massowrate
ThemassowratecanbedeterminedwiththeMINITRAC31in
conjunctionwithaowmeter.

Point level detection
Forleveldetection,thesensorisgenerallymountedhorizontallyatthe
height of the requested limit level. Make sure that there are no struts
or reinforcements at this position in the vessel.
Direct the exit beam of the source container exactly towards the
measuring range of MINITRAC 31.
