Warning & Status Messages
FLOW RATE ERRORS
No flow signal
Interpretation:
This message appears when the transducers cannot send or
receive signals to each other.
Response:
Firstly check that all cables are connected, transducers are on the pipe
correctly with sufficient couplant on the face.
This condition could also be due to a partially empty pipe, aerated liquid, particulate
content too high or when the condition of the pipe being measured is poor.
Flow signal is poor
Interpretation:
This warning appears when the signal is lower than 25%.
Response:
This could be due to an application problem, a poor quality pipe – see
also the conditions for No flow signal (above). Check for sufficient couplant.
