FMM50 Installation Steps and Precautions
Installation Steps
- Confirm that the pipeline is filled with liquid and the flow direction is consistent with the sensor arrow.
- Ensure the length of upstream and downstream straight pipe sections: upstream ≥5D, downstream ≥3D (D is the pipe diameter).
- Align the sensor flange with the pipeline flange, tighten the bolts evenly, and avoid lining deformation.
- Connect the converter cable, and note that the shielded wire should be grounded at one end.
- After power-on, perform parameter settings and zero calibration according to the manual.
Precautions
- Avoid installation near strong electromagnetic interference sources.
- Ensure there is no negative pressure in the pipeline to prevent lining detachment.
- For media prone to deposition, it is recommended to clean the electrodes regularly.
FMM50 Common Issues and Maintenance
- No flow signal: Check the power supply, cable connections, and medium conductivity.
- Fluctuating measurement values: Confirm good grounding and eliminate bubble interference.
- Zero drift: Re-execute zero calibration and ensure the pipe is full and static.
Regular maintenance can extend the service life of the FMM50. It is recommended to check the electrode and lining status every six months.
