The electrodes in the Rosemount 8705 sensor are properly orientated when the two
measurement electrodes are in the 3 and 9 o’clock positions, as shown on the right of
Figure 4.
The electrodes in the Rosemount 8711 are properly orientated when the top of the sensor is
either vertical or horizontal, as shown in Figure 5. Avoid any mounting orientation that
positions the top of the sensor at 45° from the vertical or horizontal position.

NSTALLATION
Flanged Sensors
Gaskets
The sensor requires a gasket at each of its connections to adjacent devices or piping. The gasket
material selected must be compatible with the process fluid and operating conditions. Metallic or
spiral-wound gaskets can damage the liner. Gaskets are required on each side of a
grounding ring. All other applications (including sensors with lining protectors or a grounding
electrode) require only one gasket on each end connection.
Flange Bolts
NOTE
Do not bolt one side at a time. Tighten each side simultaneously. Example:
1. Snug left
2. Snug right
3. Tighten left
4. Tighten right
Do not snug and tighten the upstream side and then snug and tighten the downstream side.
Failure to alternate between the upstream and downstream flanges when tightening bolts
may result in liner damage.
