4.8 Installation examples for ULM-3D-1
Fig. 4.13, items A and B show examples of level transmitter installation in accor-
dance with the requirements of this manual. Fig. 4.13 option A shows the installa-
tion of level transmitter on the tank flange without a nozzle, option B shows instal-
lation with a nozzle. Options C-E show typical installation errors that should be
noted.
Option C – the edge of the roof under the nozzle protrudes into the nozzle, besides,
the opening in the roof is less than the minimum permissible one.
Option D – the lower edge of the nozzle is buried relative to the roof, so the nozzle
length is more than permissible one.
Option E – level transmitter is installed with a large offset relative to the vertical
nozzle axis. The device should be installed on the central nozzle axis.
