FlowLine EchoBeam LR80 Series Manual page 29

Install the Transmitter
SIDE WALL
The minimum distance (independent of beam angle) that
the transmitter can be mounted next to the straight side
wall of the tank is 7.9" (200mm) for the LR80, LR81 and
LR83 series and 19.7" (500mm) for the LR85 series as
measured from the transmitter centerline to the side wall.
If you are not able to install the sensor more than 7.9"
(200mm) / 19.7" (500mm) away from the side wall, or if
there is material build up on the side wall (within the
beam angle), perform a False Echo Curve during initial
configuration.
DOME TOP TANKS
In metal tanks, avoid mounting the sensor in the center of a dome top tank. The center of such a tank will
multiply the echoes, making sensor operation difficult.
Note: EchoBeam can be mounted in the center of a non-metallic tank.
Correct Mounting
Sensor mounted off center in a dome top tank.
Incorrect Mounting
Do not mount sensor in the center of a domed top
tank that results in multiple echoes.
