When customers encounter “signal problems”, they usually want to restore normal operation quickly. Providing self-operable troubleshooting steps can reduce the pressure on Support. The steps are as follows:
- First, check the probe installation and coupling:
- Confirm whether the probe is closely attached to the pipeline and whether the screws are tightened.
- Remove the probe, check for oil stains or rust on the contact surface between the pipeline outer wall and the probe. After cleaning, reapply the special coupling agent (with a thickness of approximately 1-2mm, evenly covering the bottom surface of the probe).
- Then, check the installation location:
- If installed near elbows or valves, try moving the probe upstream or downstream to ensure that the straight pipe section upstream is ≥ 10 times the pipe diameter and that downstream is ≥ 5 times the pipe diameter. Avoid areas with pipeline welds or severe scaling.
- Finally, check the parameters and medium:
- Enter the host menu and verify whether parameters such as “pipeline inner diameter, wall thickness, and material” are consistent with the actual conditions (e.g., incorrectly entering DN100 as DN80 will cause abnormal signal recognition).
- Confirm whether there is actually fluid flowing in the measured pipeline (e.g., whether the valve is closed) and whether the medium temperature is within the applicable range of the flow meter (e.g., a low-temperature probe is required for temperatures < -20℃).
