Figure 12 Horizontal alignment
1 Bubble level 2 Bail
5.1.2.4 Align the sensor vertically – Flo-Dar without SVS
The sensor must be aligned vertically to make sure that the sensor is above the flow and that the
radar beam will not be stopped by the wall or pipe. Refer to Figure 13.
1. Make an estimate of where a line that extends from the top of the radar lens perpendicular to
where the lens will point. Refer to Figure 13.
2. Loosen the clamp on the wall mount bracket and put the frame so that the radar beam will point
below the crown of the pipe by at least 25.4 mm (1 in.). Refer to Figure 13. It may be necessary
to install the 12-inch spacer to extend the frame farther from the wall.
3. Tighten the clamp and measure the frame position. Make sure that the radar beam is not stopped
by the wall or pipe. If the beam is stopped, move the frame further away from the wall with the 12-
inch spacer or lower the frame.
