INSTALLATION INSTRUCTIONS, SINGLE SUPPORT
1. Choose the proper location to install the ASF Ellipse using AGA/ASME standards (or equivalent). See "Location Instructions"
on page 7.
2. Grind the surface of the pipe where the ASF Ellipse is to be inserted to provide a clean area for welding.
3. Drill a hole through the pipe wall according to Table 2.
Model / Sensor Weld Connector Drill Bit
ASF (7/8") 1" 1-1/8"
ASF1 (1-1/4") 1-1/4" 1-3/8"
ASF2 (2-1/4") 3" 2-3/4"
Table 2: Single support drill bit size
4. Deburr the hole just drilled, especially on the inside of the pipe.
5. Weld the mating ange assembly to the pipe. Align the holes. Allow 1/16" weld gap between the mounting ange and
the pipe.
6. Install the gasket and place the ASF Ellipse sensor into the pipe.
7. While holding the ASF Ellipse in its fully inserted position, align the arrow on the sensor head with the direction of ow.
See Figure 4.

8. Tighten all of the bolts on the ange and assemble all the parts that make the instrument head.
9. Connect the 1/2" tubing to the connections on the forged cross components. Connect these lines to a three-valve
manifold transmitter.
10. 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.
11. Slowly pour water into the top ports of each forged cross tee until the system is full. Water will ow out of the side ports of
both crosses.
12. Reinstall the 1/2" plugs into the top and side ports. Ensure that they are secure. Fully open the two gate valves.
13. Allow condensation levels to stabilize for 30 minutes before taking an instrument reading.
