Installation
3.2.2.3 Install the sensor on the frame
The sensor fits in the frame in only one direction and locks in position when the bail on
the sensor is turned (
Figure 10
). The sensor can be removed from the frame and installed
without entering the manhole when the optional retrieval pole is used (see
Accessories
on page 37
).
Procedure
1.
Make sure that the cable is tightly connected to the sensor.
2.
Turn the bail to retract the locking bars on the sensor.
3.
Position the sensor on the frame. The cable should point toward the center of
the manhole.
4.
Turn the bail to lock the sensor on the frame (
Figure 10
).
3.2.2.4 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 blocked by the wall or pipe (
Figure 11
).
Procedure
1.
Make an estimate of where a line that extends from the top of the radar lens
perpendicular to where the lens will point (
Figure 11
).
2.
Loosen the clamp on the wall mount bracket and position the frame so that the radar
beam will point below the crown of the pipe by at least 1 inch (
Figure 11
). 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 blocked by the wall or pipe. If the beam is blocked, move the frame further away
from the wall using the 12-inch spacer or lower the frame.
