INSTALLATION INSTRUCTIONS, SINGLE SUPPORT
1 . Choose the proper location to install the AR Ellipse using AGA/ASME standards (or equivalent) . See "Preso Ellipse Location
Instructions" on page 7 .
2 . Grind the surface of the pipe where the AR Ellipse is to be inserted to provide a clean area for welding .
3 . Weld the supplied thread-o-let to the pipe using standard codes for your application (1/16" weld gap recommended) . Take
care to protect the threads during the welding process .
4 . Drill a hole through the pipe wall according to Table 2 .

5 . Deburr the hole just drilled, especially on the inside of the pipe .
6 . Assemble the supplied compression fitting as diagrammed in
Figure 5 . Thread the assembled compression fitting into the
thread-o-let manually . With a wrench, tighten the body of the fitting a further 1-1/4 turns taking care not to tighten the
compression nut .
7 . Install the instrument valves (optional) at the AR Ellipse head connections . Ensure that the valves are FULLY CLOSED to
prevent them from leaking during startup .
8 . Insert the AR Ellipse through the compression fitting . Carefully push the sensor by hand further into the pipe until it
reaches the opposite wall .
9 . While holding the AR Ellipse in its fully inserted position, align the arrow located on the sensor head with the direction of
flow . See Figure 6 .
