Rosemount Tank Radar AB REX 用户手册

When constructing new tanks, an 8" still pipe or larger is recom-
mended. This is especially relevant in tanks with sticky, viscous
products. Before manufacturing a new still pipe, we recommend
that you contact the Project Department at Saab Tank Control for
advice. See also drawing with recommendations for still pipe
dimensions, see list of drawings in chapter 13.

For highest performance, the total area of the slots or holes in the
still pipe must not exceed the values shown in table 10.2 below.
The area in the table is the total area of the holes over the entire
length of the pipe, regardless of its length. In some cases it is pos-
sible to allow a larger area of the holes in the still pipe, than the
area stated in table 10.2. When the limits are exceeded, please
contact Saab Tank Control for advice.

See installation drawing for requirements on the service space. It is
necessary to have this free space when installing the gauge, when
doing service on it and when hand dipping or taking samples. The
height of the free space requirement depends on which Transition
Cone that is used. The larger Transition Cones require higher free
space.
