(2) Pipe Orientation
The detector may be installed in horizontal, vertical or sloping pipe runs as shown in
Figure 4.5. However, except for horizontal installation, fluid should flow from lower to
upper directions. If no air bubble, vertical down flow application are acceptable under
pressured piping conditions. See Figure 4.5.
The electrodes should be positioned horizontally relative to the ground surface in any piping
installation. See Figure 4.6.
