Unable to generate valid velocity
Error
data set.
3: Velocity Filter Error An error occurred while setting the
filter clock.
5: Velocity Gain Error Unable to set gain after maximum
attempts.
6: Level too Low error The absolute level is too low to
attempt velocity measurement.
7: Timeout/Quality

Error
meet measurement quality
requirements.
C-4
Table C-1 Definitions of 360 Error Codes
Meaning
An error occurred during an ultra-
sonic reading. This includes com-
munication errors with the
ultrasonic sensor or the level is
below the "minimum level for
velocity" threshold.
The DSP detected a noise level in
the doppler signal that is higher
than the calibrated noise thresh-
old.
An error occurred while focusing
the laser.
An error occurred during commu-
nication with the DSP.
Communication failed between
flowmeter and sensor. This could
be due to the sensor being dis-
connected, losing power, etc.

Possible Solutions
Ensure the blanking distance is correct. Refer to Sec-
tion 3.2 Measurement Setup.
Ensure the placement of the sensor is accurate. Refer
to Section 2.5.3 Sensor Positioning and Require-
ments.
Verify there is no foam, steam, or extreme turbulence.
Contact factory.
Contact factory.
Contact factory.
Ensure the sensor is connected to the flowmeter.
Ensure the input voltage is 9V (minimum).
Verify the battery is connected or charged.
Possible Solutions
Contact factory.
Ensure there are uniform flow conditions at sensor
location.
Ensure there is no debris on the sensor.
Place sensor in flow with at least 1" deep.
Set storage of velocity to be secondary based on
depth of 1".
Contact factory.
