§6.3 Other Problems and Solutions
Q: Why does the instrument display 0.0000 flow rate while the liquid in the pipe is actually flowing? The
signal strength, R, is in good range and the signal quality, Q, is a satisfactory value.
A: The problem is likely to be caused by an incorrect zero calibration. The user may have conducted the
zero point set up while the flow was not at a complete standstill. To solve this problem, press keys C1 and
follow the directions given.
Q: Why is the displayed flow rate much lower or much higher than the actual flow rate in the pipe despite
being under normal working conditions?
A: There are three possible explanations for this error:
1) The entered offset value may be incorrect. Enter “0” offset in window S44. Please see Section
§4.11 for more information on changing the scale factor.
2) Incorrect transducer installation. Re-install the transducers carefully.
3) The zero calibration was set wrong. Press keys C1 and redo the zero calibration setup. The flow
inside the pipe needs to be at a standstill. This menu can be accessed as follows: CAL

Q: Why is there no signal even when the installation requirements are met, pipe is new, and pipe material
is in good quality?
A: Check the following:

Is the installation method suitable for the pipe size?

Are the entered installation parameters correct?

Are the wirings correct?

Is there adequate couplant? Are the transducers in good contact with pipe?

Is the pipe full?

Is the distance between the transducers true to the value shown in window S43? Accessed as

set-up process, which was accessed on Step 5 under the Quick Start menu window (S1, Step 5).

Are the transducers facing the right direction?
Q: If the pipe in use features a heavily scaled inside, and/or poor or no signal detected, is it possible to
conduct a measurement? Are there options for conducting a measurement on an old pipe?
