IV. INSTALLATION INSTRUCTIONS - SINGLE SUPPORT
1. Choose the proper location to install the PFA Ellipse using AGA/ASME standards (or
equivalent). Refer to the Location Instructions on
Page 8
.
2. Grind the surface of the pipe where the PFA Ellipse is to be inserted to provide a clean area for
welding.
3. Weld the supplied weld-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 1 .
5. Deburr the hole just drilled, especially on the inside of the pipe.

6. Install the supplied compression fitting by threading it into the weld-o-let manually. Then with
a wrench, tighten the fitting a further 1¼ turns taking care not to tighten the compression nut.
7. Install the instrument valves at the PFA Ellipse head connections. Ensure that the valves are
FULLY CLOSED to prevent them from leaking during start-up.
8. Insert the PFA Ellipse through the compression fitting See
Figure 3
. Carefully push the sensor
by hand further into the pipe until it reaches the opposite wall.
9. While holding the PFA Ellipse in its fully inserted position, align the arrow located on the sensor
head with the direction of flow. See Figure 4 .
10. Thoroughly tighten the compression nut in order to prevent leakage. After tightening the
compression nut manually, turn it further 1¼ turns with a wrench.
