Badger Meter AS - Steam (2 to 72")" - Manual (Page 5)

INSTALLATION INSTRUCTIONS, SINGLE SUPPORT
1 . Choose the proper location to install the AS Ellipse using AGA/ASME standards (or equivalent) . See "Location Instructions"
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 .
5 . Deburr the hole just drilled, especially on the inside of the pipe .

6 . Assemble the supplied compression fitting as diagrammed in Figure 3 . Thread the assembled compression fitting into
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 .
7 . Install the instrument valves (optional) at the AS Ellipse head connections . Make sure the valves are FULLY CLOSED to
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 .
9 . While holding the AS Ellipse in its fully inserted position, align the arrow on the sensor head with the direction of flow . See
Figure 4 .

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 .
