Problem
Inaccurate The pipe or channel where the sensor
measurements is installed is small or too narrow. The
ultrasonic signal bounces off the sides
of the pipe or channel.
The sensor is in direct sunlight.
The temperature of the sensor
environment has changed quickly.
The sensor is too far away from the
surface of the measurement target.
Measurement Foam, oil, debris and surface
failure turbulence are affecting the send and
receive signal.

Solution
Install the sensor in a larger diameter pipe or
move the sensor nearer to the water surface.
Keep the downlooking sensor a minimum of
13.34 cm (5.25 in.) from the water surface. Keep
the in-pipe sensor a minimum of 0 cm (0 in.) from
the water surface.
As an alternative, increase the minimum distance
value to a location below the false target that is
affecting measurements.
Do not let the sun shine directly on the sensor.
Make a sun-shield if an alternative location is not
available. Contact technical support for ideas for
the specific environment.
Let the sensor stabilize after large changes in the
temperature of the environment.
Install the sensor near the surface of the
measurement target.
Clean the sensor. Refer to
on page 15.
