5. Troubleshooting
Determine Fault:
Please confirm there are no issues with First check Items above before continuing.
Symptom: No/Low Signal Quality
Verify the meter is installed correctly and that the application has been configured correctly by
using the tables below. Ensure the pipe is full and there is no air present in the pipe. Ensure there
is no paint or corrosion on the pipe where the transducers are mounted. Check that the
transducers are clamped securely to the pipe surface.
Symptom: No Flow Reading When Flow is Present
Verify the signal quality is above 85. If it is not, check that the pipe is full and there is no air
present in the pipe. Verify the meter is installed correctly and that the application has been
configured correctly by using the tables below.
Symptom: Erratic Output
Verify the signal quality is a consistent number above 85. Ensure that the pipe is full and there is
no air present in the pipe.
Symptom: Flow Reading When No Flow is Present
A meter zero needs to be performed. In Engineer Menu 1 (password 208.), press down until you
reach Zero Cutoff. Select Yes when pipe is full and has no flow.
Symptom: No RTD Temperature Reading
Ensure the RTDs are properly wired.
Error Codes and Possible Solutions:
Codes Meaning Causes Solutions
*R System Normal * System normal
*E Signal Not Detected * Signal not detected
* Spacing is incorrect between the
transducers or not enough
coupling compound was applied
to the face of the transducers
* Transducers installed improperly
* Scale is too thick
* New pipe liner * Attach transducer to the pipe
and tighten it securely. Apply
plenty of coupling compound onto
transducer and pipe wall.
* Remove any rust, scale, or
loose paint from the pipe surface.
Clean it with a file.
* Check the initial parameter
settings
* Remove the scale or change the
scaled pipe section.
* Wait until liner is solidified and
saturated.
*D Adjusting Gain * Adjusting gain for normal
measurement
