on page 7

.

2 . Grind the surface of the pipe where the AS 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 2

the weld-o-let manually . With a wrench, tighten the body of the fitting another 1-1/4 turns, taking care not to tighten the

compression nut .

prevent them from leaking during startup . Install the two forged crosses to the valves .

8 . Insert the AS Ellipse through the compression fitting . Carefully push the sensor by hand further into the pipe until it

reaches the opposite wall .

10 . To prevent leakage, manually tighten the compression nut, the use a wrench to tighten it another 1-1/4 turns .
11 . Connect the 1/2" tubing to the connections on the forged cross components . Connect these lines to a three-valve

manifold transmitter .

12 . Verify that the instrument valves are FULLY CLOSED . Remove the 1/2" plugs from the top and side ports of the two forged

cross tees .

13 . Slowly pour water into the top ports of each forged cross tee until the system is full . Water will flow out of the side ports of

both crosses .

14 . Reinstall the 1/2" plugs into the top and side ports . Ensure that they are secure . Then fully open the two gate valves .
15 . Allow condensation levels to stabilize for 30 minutes before taking instrument reading .
