Emerson Rosemount 5900S Series, Reference Manual, Page: 46 / 298

Extension pipe for minimum distance
The Rosemount 5900S Radar Level Gauge should be placed such that there is a minimum
gap of 1200 mm (47 in.) between the flange and the maximum product level (see
Still-
pipe and Verification Pin ). If necessary, an extension pipe can be used to raise the level
gauge. This will allow measurements closer to the top of the tank than would otherwise be
possible, as illustrated in
Figure 3-16 .
