Leveling the ultrasonic depth sensor
If necessary, adjust the level in the following way:

Remove the ultrasonic depth sensor from the mount.
 Loosen the ring slightly to allow the plate to move on the
ring.
 Tap the sensor mount to the right or left with a rubber
mallet until it is level.
Warning:
Tapping the sensor mount with the sensor
attached could damage the sensor. Always remove the
sensor before tapping the mount with a mallet.
 Reattach the sensor to the mount, and recheck the level.

against the pipe wall.
